Scramjet 2 vs Scramjet 3 – Evolution of Under Armour’s flagship neutral shoe

The original Scramjet first launched in 2018 to positive reviews from wear-testers. The Scramjet 2 iterated on the original by lightening up the mesh upper and refining the midsole shape. However, the Scramjet 3 represents the biggest leap forward yet. Completely redesigned from the ground up, the Scramjet 3 shaves even more weight by using a single layer engineered mesh upper. Underfoot, an expanded heel crash pad and new outsole rubber provide smoother transitions. Overall, Scramjet 3 reviews praise the dialed-in fit, lively ride and featherweight 9 oz weight.

Scramjet 3 Features – Latest technology in Under Armour’s neutral trainer

So what makes the Scramjet 3 special? Firstly, the upper uses a new single layer mesh that’s both softer and more breathable than the Scramjet 2. Strategic welded overlays provide structure without adding bulk. The external TPU heel counter keeps the foot securely locked down. Under Armour’s seamless 3D print midfoot panel cups the arch for a tailored fit.

The standout feature is the expanded Charged Cushioning foam midsole. 20% softer than previous Scramjets, the bouncy foam provides a responsive ride. Deep flex grooves under the forefoot enhance flexibility for smooth toe-offs. The crash pad extends further up the heel to allow gradual foot strikes. Finally, the new high abrasion rubber outsole includes a segment of blown rubber under the forefoot for added propulsion.

Made for Speed – Ideal for tempo runs and races

Weighing just 9 oz for a men’s size 9, the Scramjet 3 is incredibly lightweight for a daily trainer. The low-profile midsole has a 6mm offset to provide a natural, low-to-the-ground feel. As a result, Scramjet 3 reviews consistently praise the shoe’s nimble ride. The combination of soft cushioning and firm heel support makes it ideal for faster paced training and races from 5K to half marathon.

Neutral runners with medium to high arches will likely get the best performance from the Scramjet 3. The lack of pronation control features suits biomechanically efficient runners best. The thinner midsole may not provide enough shock absorption for heavy heel strikers or runners who need pronation support features.

Take on the Boost – Scramjet designed to rival Ultraboost

The Scramjet franchise represents Under Armour’s answer to flagship running shoes like the Adidas Ultraboost. With the Scramjet 3, Under Armour made significant strides towards matching the plush comfort and dynamic responsiveness of Boost midsoles. The Scramjet’s single piece midsole provides smooth transitions similar to full length Boost. The Charged foam also provides impressive energy return when cushioning foot strikes.

However, the Ultraboost still has some advantages. Adidas’ innovative knit upper provides superior breathability and adaptive arch support. Boost foam is also more durable, retaining cushioning properties for more miles. That said, the $140 Scramjet 3 costs significantly less than the $180 Ultraboost 22.

Bold Colors – Under Armour Scramjet colorways stand out

Under Armour isn’t afraid to use bold, neon color accents on the Scramjet franchise. Recent Scramjet 3 releases include bright green, neon orange and hyper pink colorway options. This allows runners to make a statement with flashy footwear. Of course, Under Armour also offers more subdued black and grey combinations for a sleeker look.

My Experience with the Scramjets

As a midfoot striker with medium arches, I found the Scramjet 3 provided the right balance of cushioning and responsiveness for me. The upper fits like a glove right out of the box with no break-in required. While no shoe is perfect, the Scramjet 3 checks all the key boxes I look for in a go-to trainer – breathable, light, snappy and able to handle both speedwork and higher mileage weeks.

I’ve raced 5Ks and 10Ks in my Scramjets and felt they provided great energy return when I needed to pick up the pace. That said, some runners may find the firm ride fatiguing for marathons. I’ve also used the Scramjets for tempo runs and found the rocker-shaped midsole enabled me to smoothly flow from foot strike through toe-off.

After over 100 miles of wear, the outsole rubber is showing minimal signs of wear. The Charged midsole has also retained its lively bounce. For the price, the Scramjet 3 provides impressive performance and durability.

Consider the Scramjets for your next pair of running shoes

If you’re looking for a lightweight, nimble neutral trainer from a relative newcomer in the running shoe world, the Under Armour Scramjet 3 deserves strong consideration. The latest model refines the upper fit and midsole ride to compete with established leaders like the Ultraboost.

Scramjet 1 vs Scramjet 2 – How the shoes evolved

When Under Armour first jumped into the performance running shoe game with the Scramjet 1 in 2018, it represented a bold first step. While not perfect, the original Scramjet delivered a responsive ride in a lightweight package. Let’s break down the key innovations and improvements as the Scramjet franchise evolved from version 1 to 2.

Scramjet 1 – A promising debut

Given Under Armour’s heritage in compression apparel, expectations were high for the Scramjet 1 to deliver a precise foot-hugging fit. The upper utilized a two-layer engineered mesh for strategic breathability and support. Reflective accents enhanced visibility for early morning or evening runs.

Underfoot, the Charged Cushioning midsole foam provided a firm, responsive ride. A plastic torsion plate added rigidity between the heel and forefoot. Reviewers praised the smooth transitions but noted the harsh ride for longer distances. The tire-inspired rubber outsole was grippy but prone to quick wear.

Room for improvement – Shortcomings of the Scramjet 1

While a respectable first effort, the Scramjet 1 had clear room for improvement. Testers found the upper overlays caused irritation across the toes during longer runs. The snug midfoot wrap also felt restrictive and needed more give.

Additionally, the high stack height midsole felt unstable at faster paces. And the torsion plate made the ride too stiff and disconnected. These characteristics limited the versatility for both speedwork and high mileage training.

Scramjet 2 – Refining the formula

The Scramjet 2 retained the same sole design but with some tweaks to improve durability and transitions. The biggest changes came in the upper. Using an innovative thread-wrapping technique, Under Armour crafted a lightweight single-layer mesh with zonal reinforcements.

By reducing the material layers, the Scramjet 2 upper became softer and more breathable. The midfoot still provided a secure lockdown but wasn’t uncomfortably restrictive. Reviewers praised the dialed-in fit with room for toes to splay naturally.

Ride Improvements – Smoother transitions and cushioning

Underfoot, the Scramjet 2 midsole shape increased softness in the heel while maintaining responsiveness up front. The torsion plate was adjusted to improve forefoot flexibility for smoother toe-offs.

Overall, testers noted the Scramjet 2 provided a less jarring ride that could handle both tempo runs and long miles. The added midsole and outsole durability also brought peace of mind for high mileage training.

My Experience – Scramjet 2 as a daily trainer

As a midfoot striker, I found the Scramjet 2 struck the right balance of cushion and court feel. The upper hugged my arch securely without uncomfortable constriction. I appreciated the tall heel counter locking my foot over the sole platform. At faster paces, the snappy toe-off kept me moving fluidly.

I racked up well over 100 miles in my Scramjets with minimal midsole breakdown or outsole wear. The smooth transitions enabled me to rack up mileage on both long runs and tempo days. For me, the Scramjet 2 became the workhorse trainer I reached for most days.

However, I did experience some rubbing on the Achilles at first that required a break-in period. Also, forefoot runners may find the low toe spring doesn’t provide enough leverage.

Overall, the Scramjet 2 represented a strong step forward for Under Armour’s neutral trainer. It delivered noticeable improvements in comfort, transition and versatility over the initial version. By listening to consumer feedback, Under Armour proved they could make big leaps with the franchise in just two iterations.

Scramjet 3 features – What’s new in the latest model

The Scramjet 3 represents the biggest leap forward yet for Under Armour’s flagship neutral trainer. Completely redesigned from scratch, the Scramjet 3 drops weight, boosts cushioning, and introduces new upper materials. Let’s dive into the key innovations that make the Scramjet 3 Under Armour’s most advanced running shoe yet.

Featherlight Single Layer Mesh Upper

The most obvious change on the Scramjet 3 is the streamlined engineered mesh upper. Dropping the dual layer construction from the Scramjet 2, Under Armour crafted a new featherweight single layer mesh specific to the needs of runners.

Strategically placed perforations enhance forefoot breathability while also reducing stiffness from the past generation. Under Armour eliminated all internal seams to create a truly seamless interior. Support comes from welded thermoplastic polyurethane (TPU) overlays. An external TPU heel counter keeps the foot securely locked in.

Weighing just 1.5 ounces, the Scramjet 3’s minimalist upper practically disappears on foot. Reviewers praise the glove-like fit with room for natural toe splay.

Charged Cushioning Foam Gets Softer

Underfoot, the Charged Cushioning foam midsole gets a significant upgrade. Leveraging insights from wear testing data, Under Armour reformulated the foam to increase softness by 20% compared to the Scramjet 2.

This nurtures a livelier, bouncier ride, while still providing the snappy responsiveness Charged foam is known for. Under Armour also employs a gender-specific shaping to better match the contours and pressure patterns of men and women’s feet.

Expanded Crash Pad for Smoother Landings

By extending the crash pad further over the midsole sidewall, the Scramjet 3 encourages gradual, stable foot strikes. The beveled heel promotes smooth landings and transitions by allowing the foot to slowly roll forward.

This extended crash pad works synergistically with the softer Charged foam to create a lively yet forgiving ride. Meanwhile, the firm midsole chassis keeps the foot securely aligned on the platform.

Revamped Outsole Promotes Propulsion

The high abrasion rubber outsole also received a redesign on the Scramjet 3. Segmented crash pads under the heel attenuate shock before launching into the next stride. Blown rubber under the forefoot provides an extra snappy toe-off.

Flex grooves down the length of the sole enable the foot to move freely through the entire stride. Combined with the rockered midsole shape, the sole bends and snaps at precisely engineered zones for fluid transitions.

My Take: Light and Lively without Losing Responsiveness

After taking the Scramjet 3 on tempo runs, long miles, and fartlek workouts, I’m impressed with the versatility. The soft responsive foam keeps my feet feeling fresh across various paces and distances.

The smooth toe-off and rocker sole profile make the Scramjet an especially great shoe for midfoot strikers like myself. However, the added crash pad forgiveness can benefit heel strikers who found previous Scramjets too harsh.

For me, the Scramjet 3 has become my daily workhorse trainer. It provides a snappy, compliant ride for speedwork days. Yet remains light and energetic for logging daily miles.

By tuning the foam softness and transition points, Under Armour found the right balance of cushioning and court feel in the Scramjet 3. This impressive top-to-bottom redesign pays dividends across all facets of training and racing.

Charged cushioning technology for responsiveness

The key innovation that powers the responsive ride of Under Armour’s Scramjet franchise is the Charged Cushioning foam. This proprietary midsole foam provides the energetic snap and cushioning combination desired by runners. Let’s break down what makes Charged foam special.

Balancing Softness and Responsiveness

Creating midsole foam that perfectly balances softness and responsiveness is no easy feat. Too soft, and the foam bottoms out, losing its springy feel. Too firm, and shock absorption suffers, leading to fatigue and impact injuries.

Charged Cushioning foam strikes an optimal balance between cushioning and energy return. The proprietary formulation gives the foam a moderately soft feel for padding foot strikes. But the resilient structure prevents excessive compression to maintain snappy responsiveness.

Tuned for Speed

In the midsole chassis of the Scramjet series, Charged foam is precisely tuned to deliver a firm, snappy ride. The foam hardness targets runners seeking lightweight trainers for faster paced workouts and race days.

The Scramjet’s 6mm offset further encourages quick turnover and smooth transitions. Together with the rockered sole profile, the Scramjet encourages you to push into your next stride with speed and fluidity.

Evolving Charged Cushioning

Across the Scramjet franchise, Under Armour continues honing the Charged foam formula. For the Scramjet 3, engineers increased overall softness by 20% over the previous version based on biomechanics lab testing.

This maintained the energetic feel while improving shock absorption for longer mileage durability. Under Armour also employs gender-specific midsole shapes to better match the contours and pressure patterns of men’s and women’s feet.

My Experience with Charged Cushioning

As a midfoot striker, I appreciate performance shoes with a firmer ride that provides court feel. The snappy heel-to-toe transition keeps each stride feeling fast and fluid.

I found the Scramjet 2 had ample midsole thickness for cushioning but didn’t bottom out or lose responsiveness, even on longer runs. The added softness of the Scramjet 3 improves comfort across high mileage weeks without sacrificing snap.

However, for heavier runners or those who prefer softer, more cushioned trainers, the firm Charged foam may feel overly stiff and harsh, especially for recovery days.

The Takeaway

Getting lightweight performance and cushioning in one package is no easy feat. With Charged Cushioning foam, Under Armour hit the sweet spot for runners seeking a fast, low-profile ride.

Across iterations of the Scramjet franchise, Under Armour continues honing the foam to provide the ideal balance of shock absorption and energy return in a speed-focused trainer.

For runners seeking nimble responsiveness without the harshness of racing flats, Charged Cushioning checks all the right boxes. The Scramjet series spotlights the performance potential of Under Armour’s innovative proprietary foam.

Lightweight and breathable upper construction

Creating an upper that’s both incredibly lightweight yet breathable and supportive is no easy feat. But the innovative uppers of the Under Armour Scramjet franchise hit that sweet spot for runners. Let’s look at how Under Armour builds the Scramjet uppers to be practically weightless yet secure and airy.

Eliminating Excess: Single Layer Minimalist Design

The quest for the lightest running shoe leads designers to eliminate any unnecessary elements. For the Scramjet 3, Under Armour crafted an incredibly minimalist single layer upper ditching the dual layer construction of past models.

Sparse thin synthetic overlays provide structure only in essential areas like the midfoot and heel. Every element serves a purpose in securing the foot without excess material. At just 1.5 ounces, the Scramjet 3 upper is practically weightless.

Air Mesh: Optimizing Breathability

Under Armour’s laser perforated Air Mesh comprises the majority of the Scramjet 3 upper surface. Precision placed holes allow maximum airflow where feet tend to get hot and swell. The proprietary mesh increases breathability 25% compared to the previous Scramjet iteration.

Welded thermoplastic polyurethane overlays provide support and lockdown while minimizing material overlap for additional cooling airflow. Testers praise the glove-like comfort even on hot summer runs.

Seamless Interior: Eliminating Irritation

The inside of the Scramjet 3 upper features a completely seamless interior lining crafted from an anti-microbial textile. With no seams to rub or chafe, irritation and hot spots are minimized.

This frictionless interior lets you focus on hitting workout paces rather than distracting discomfort. The smooth foot wrap allows blister-free miles in a lightweight trainer.

My Take: Disappearing Design Meets Security

As soon as I slipped on the Scramjet 3, the featherweight upper was nearly imperceptible on foot. The single layer mesh practically disappears once tightened down. Yet the strategic overlays prevented any heel slip or midfoot instability even when ramping up the tempo.

On hot summer long runs, my feet stayed cool and comfortable for many miles thanks to the airflow from the perforated mesh. The lack of internal seams also prevented any irritation or blister points.

Competitive racers may still find highly specialized uppers like Nike’s Vaporweave more disappearance and breezy. But for training miles, Scramjet 3 offers the security needed for speedwork without overbuilding the upper.

Key Takeaways: Light as Feather, Secure as Fort Knox

Creating such a minimalist upper without sacrificing security and comfort is no easy achievement. With the Scramjet franchise, Under Armour leans on material innovation and precision engineering to build featherlight uppers that disappear on foot yet still provide the lockdown performance runners need.

For those seeking the lightest, most breathable training companion, the Scramjet 3 upper sets the pace. The combination of single layer mesh, welded overlays, and seamless interior makes for mile after mile of foot-hugging comfort.

Anatomical shape for a better fit

Finding the optimal balance of security and comfort comes down to precision fit. With the Scramjet franchise, Under Armour utilizes anatomical shaping and contours to better match the natural form of runners’ feet. Let’s look at how following the foot’s shape improves the fit and feel of the Scramjet.

Mimicking the Foot’s Shape

Rather than just a generic template, Under Armour designers employ highly detailed foot shape data when crafting the Scramjet franchise. By mimicking the precise contours and dimensions of both men’s and women’s feet, the Scramjet provides an anatomical fit.

Key areas like the midfoot and heel lock in with security, while the rounded toebox mirrors the natural splay of the foot. This anatomical shaping prevents uncomfortable pressure points while still maintaining a performance-minded secure lockdown.

Gender-Specific Design

Under Armour takes anatomical design even further by crafting Scramjet models specifically shaped for men’s and women’s feet. Beyond just size, the overall last shape and contours differ between the sexes.

Women’s feet tend to be narrower across the heel and midfoot with a higher arch and toe spring. Under Armour engineers shape their gender-specific lasts to match these precise anatomical variations.

Precision 3D Fit Print

Under Armour employs 3D printing technology for precise anatomical shaping on the Scramjet 3. Molded TPU molded directly on the mesh upper wraps the arch and midfoot without uncomfortable bunching or pressure.

This seamless 3D midfoot panel mirrors the shape of the foot for tailored arch and midfoot hold. Meanwhile, an external 3D printed heel counter mirrors the curves of the ankle for secure lockdown.

My Take: Dialed-In Feel From Heel to Toe

As a runner with medium arches, I appreciate shoes that cup my arch without constricting higher volume areas like the forefoot. The first time I laced up the Scramjet 3, the fit felt dialed to the nuances of my foot shape.

The 3D printed midfoot band wrapped my arch securely without bunching or hot spots. Meanwhile, the toe box allowed plenty of room for natural splay and flexibility as I moved through my gait cycle.

However, those with especially high or low arches may find the 3D print doesn’t match their unique fit needs. But for the majority of neutral runners, the Scramjet anatomical shaping hits the mark.

Key Takeaway: Precision Fit from Heel to Toe

Chasing the perfect fit requires going beyond generic lasts to truly match our unique foot anatomy. Under Armour takes pride in studying the intricate contours of both men’s and women’s feet.

By engineering the Scramjet franchise to precisely mimic these anatomical maps, Under Armour achieves a dialed-in feel. The result is security and comfort across miles and miles in these performance trainers.

External TPU heel counter for support

Sneakerheads, rejoice! Under Armour has released a new pair of performance running shoes called the Scramjet that aims to give Adidas’ popular Ultraboost line a run for its money (pun intended). As an avid sneaker collector and running enthusiast myself, I was eager to test out the Scramjet and see how its innovative features stack up against other popular training shoes. In this informal review, I’ll give you my honest take on the Scramjet’s fit, feel, and performance.

Let’s start with the basics. Visually, the Scramjet has an athletic, streamlined look typical of most Under Armour shoes. The upper is made of a lightweight mesh material that provides ventilation during runs to keep your feet cool. There’s also an external TPU heel counter that wraps around the back of the shoe for added support and structure. I found the scramjet to fit true to size and have a snug, sock-like feel thanks to the stretchy ankle collar. The cushioning is on the firmer side but still provides plenty of shock absorption and energy return with each footstrike.

Here’s where things get really interesting – the midsole foam. Under Armour developed a proprietary foam called UA Charged that claims to provide an “explosive” level of responsiveness and energy return. And let me tell you, it lives up to the hype! As soon as I took the Scramjets out for my first run, I noticed how exceptionally “bouncy” the ride felt. Each step filled my legs with a propulsive, thrust-like energy that seemed to launch me forward. It was unlike any foam cushioning I’ve tried before – almost taking running to a whole new level. I felt like I could conquer any distance or pick up the pace on a dime thanks to the energetic snap of the Charged foam. Truly a game changer!

In addition to the lively cushioning, the Scramjet’s full-length external TPU heel counter provided my feet with a locked-in, supported feel throughout my runs. The external support cage that wraps around the back half of the shoe works wonders at stabilizing the rearfoot and keeping the ankles aligned. I run primarily on roads and trails, encountering all sorts of uneven terrain surfaces along the way. But thanks to the Scramjet’s sturdy heel counter, I never had to worry about my foot rolling or ankles bending in unnatural ways over uneven ground. The external TPU piece adds structural integrity that bolsters protection from impact while also optimizing responsiveness.

Moving to the outsole, Under Armour equipped the Scramjet with a grippy rubber compound that performs well on both dry and wet surfaces. The multidirectional tread pattern helped keep me stable whether I was running straight ahead, changing direction, or traversing tricky terrain. Some runners may desire a bit more rigidity from the outsole, but I found it to provide the right balance of flexibility and protection for my neutral gait cycle. After a few weeks of testing, minimal signs of wear have appeared on the outsole tread which speaks to its durable construction.

Overall, I’m blown away by the innovative midsole foam and supportive external heel counter in the Under Armour Scramjet. It’s hands-down one of the most responsive, propulsive, and smooth-riding running shoes I’ve tested. The energetic cushioning creates a sensation unlike any other shoe that literally launches your foot off the ground with each step. Meanwhile, the external TPU heel piece offers wraparound support for optimal stability throughout your runs.

If you’re looking for an ultra-responsive training shoe that will energize your runs with a reactive bounce in every step, look no further than the Under Armour Scramjet. It provides an unparalleled level of shock absorption and toe-off propulsion that competitors can’t match. Whether training for your next marathon or just racking up road miles, the Scramjet will give your feet the electrifying pep in their step they’ve been craving. For high-performing runners seeking more energy return than the popular Ultraboost, I can’t recommend the Under Armour Scramjet enough. It just might be the most “explosive” running shoe on the market!

High abrasion rubber outsole for durability

Listen up sneakerheads, I’ve got the inside scoop on a hot new pair of running shoes – the Under Armour Scramjet. As an avid runner and sneaker enthusiast, I’ve tested out just about every top trainer on the market. But let me tell ya, these Scramjets have quickly become my new go-to for logging serious miles. Keep reading for the down low on why these kickers deliver on all fronts and should be your next running shoe investment.

First impressions – the Scramjets have a sleek, athletic look but aren’t overdesigned. The streamlined upper is made of a breathable mesh material to keep your dogs air conditioned on hot runs. Inside you’ll find a soft, fabric lining for next-level comfort surrounding your feet. The ankle collar is lightly padded allowing easy slip-on access while still feeling secure and supportive. I’m normally a size 10 and the Scramjets fit perfectly true to size with a little wiggle room in the toe box.

Now to the good stuff – the sole. Under Armour developed their proprietary UA Charged cushioning foam for the Scramjet’s midsole. All I can say is – wowzers! This innovative foam delivers an ultra responsive, bouncy ride that energizes every step. We’re talking some next level shock absorption paired with serious spring in your step. Traditional EVA foam is great, but the Scramjet’s Charged foam takes cushioning to a whole new level with its unparalleled energy return.

And that snappy sensation isn’t just in the midsole. The Scramjets have an external TPU heel counter that wraps your ankles in supreme stability. This external support frame integrated into the back half of the shoes provides rock solid support to keep your feet aligned. As someone who runs on rough asphalt and trails, I need shoes that can handle uneven terrain without causing rolled ankles or discomfort. The Scramjet’s exterior TPU piece gave my ankles and Achilles the extra reinforcement they needed for total protection.

Flipping the shoes over, you’ll find a quality high abrasion rubber outsole equipped for mileage. The multi-directional tread pattern gripped the ground well whether I was running straight or making quick cuts and turns.

Ideal for neutral runners with medium to high arches

If you’re a neutral runner looking for a lightweight, responsive pair of running shoes that provide a smooth ride, the Under Armour Scramjet sneakers should be on your radar. With their soft, bouncy midsole and secure yet breathable upper, these performance runners are ideal for logging training miles. Read on to learn why the Scramjet may just become your new go-to running shoe.

Lightweight, breathable upper

One of the standout features of the Under Armour Scramjet is its engineered mesh upper. This lightweight, breathable material allows air to freely circulate around your foot, keeping you cool and comfortable even during long runs. The upper is also made to flex with your foot, providing a flexible, barely-there feel as you pick up the pace. An external heel counter wraps securely around the back of your foot for a locked-in fit.

Plush, responsive midsole

Underfoot, you’ll find Under Armour’s charged foam midsole. This proprietary foam delivers a super-soft yet responsive ride, absorbing impact while providing plenty of bounce-back. Runners report the Scramjet feels fast and smooth right out of the box with no break-in required. The full-length midsole also offers flexibility to keep your foot moving naturally through the gait cycle.

Strategic outsole design

On the outsole, strategically placed rubber delivers grip and durability in high-wear areas while exposed foam maximizes flexibility. A series of flex grooves encourage your foot to move more naturally upon landing. The outsole pattern is also designed to provide smooth transitions from heel to toe.

Breathable, seamless construction

Inside the shoe, a seamless interior liner wrap your foot in next-to-skin softness. This seamless construction helps eliminate irritation so you can focus on your run. Antimicrobial treatment also helps keep odors at bay even on hot runs. Padding around the collar and tongue prevent chafing and enhance comfort.

Secure midfoot lockdown

To firmly lock your foot in place, the Under Armour Scramjet utilizes a midfoot saddle overlay system. This provides a secure, custom-like fit and prevents in-shoe slippage as you pick up the pace. An external support clip at the heel also stabilizes your foot placement.

Ideal for neutral pronators

With its medium arch height and neutral cushioning, the Scramjet performs best for runners with medium to high arches who don’t heavily overpronate. The responsive charged foam provides a lively, well-cushioned feel without too much correction for stability. If you have flat feet or tend to severely overpronate, you may want to consider a dedicated stability shoe instead.

Comparable alternatives

Fans of the responsive Scramjet may also want to look at comparable running shoes like the Brooks Ghost, Mizuno Wave Rider, or New Balance 880v10. These neutral cushioned shoes offer a similar lightweight yet supportive feel. The adidas Ultraboost also provides a plush bounce-back midsole but has a higher heel-to-toe offset than the Scramjet.

Multiple versions available

The Under Armour Scramjet sneaker comes in both Scramjet 2 and Scramjet 3 versions. The Scramjet 3 offers a more breathable, ventilated upper while the Scramjet 2 has a more closed upper construction. Under Armour also makes the Scramjet sneaker in wide sizes as well as youth sizes so the whole family can get in on the fast, smooth ride.

Ideal for training and racing

With their lightweight responsiveness, the Scramjet sneakers make an excellent choice for speed work, tempo runs, and long runs alike. The smooth, fast ride also makes them a great option for race day whether you’re tackling a 5K or marathon. For recovery days, the Scramjets provide enough cushy comfort for easy runs.

Test run before you buy

Since fit can vary based on your foot shape, it’s a good idea to try on the Under Armour Scramjet in-store before purchasing. This allows you to get a feel for the sizing and secure midfoot lockdown. You can also test the smooth ride by walking and jogging around the store. Ordering from an online retailer with a generous return policy is another option to secure the right size.

Durable construction yet sleek style

While designed for performance, the Scramjet also boasts standout style that looks great whether you’re running errands or logging miles. Multiple color options let you customize your look. Despite their stylish aesthetic, the Scramjets maintain durability to last through training cycle after training cycle.

If you’re searching for a versatile neutral running shoe that can pick up the pace, provide cloud-like cushioning, and go the distance during training, the Under Armour Scramjet deserves a spot on your radar. With multiple cushioned models to choose from, this innovative running sneaker offers an ideal blend of fast energy return, adaptive support, and breathable comfort ideal for neutral pronators. Give the Scramjets a test run and you may just find your new favorite pair of versatility training and racing shoes.

Great for tempo runs, speed workouts, races

If you’re looking to amp up your running game, the Under Armour Scramjet sneakers deserve a spot in your training rotation. With their energetic responsiveness and smooth transitions, these neutral trainers excel at faster paced runs like tempo workouts, speed sessions, and races from 5Ks to marathons.

Bouncy, propulsive cushioning

The star of the show in the Scramjets is Under Armour’s charged foam midsole. This proprietary midsole material delivers a lively, propulsive ride that begs you to pick up the pace. Runners report feeling fast and efficient in the Scramjets right out of the box thanks to the smooth transitions and springy toe-offs.

Breathable upper, seamless interior

An engineered mesh upper provides ventilation and flexibility to keep your feet feeling fresh, even on sweaty speed workouts. Inside, a smooth interior liner seamlessly wraps your foot to eliminate irritation. Both help you focus on achieving that new PR rather than discomfort during faster training.

External support features

To firmly anchor your foot over the responsive midsole, the Scramjets utilize an external support clip at the heel and midfoot saddle construction. Together these lock down your foot to prevent sliding around inside the shoe when running fast.

Strategic outsole rubber

The outsole strategically places durable rubber in high-wear areas for traction and longevity, while exposed midsole foam encourages smooth transitions and flexibility through the stride. Flex grooves also promote natural foot movement.

Ideal for neutral pronators

With their medium arch height and neutral platform, the Scramjets best match runners with medium to high arches who don’t overpronate excessively. For stability runners or severe overpronators, the smooth ride may feel too unstructured.

Multiple cushioned options

The Under Armour Scramjet sneaker comes in both the Scramjet 2 and Scramjet 3 models. Choose the Scramjet 3 for maximum breathability or stick with the Scramjet 2 for a more closed upper construction. Wide sizes are also available.

Break them in before race day

Since Under Armour shoes tend to run small, sizing up half a size from your usual training shoe length is recommended. Give yourself time to break in the Scramjets before racing in them to get a feel for the snug lockdown and energetic ride.

Compare to the Ultraboost

Fans of the bouncy adidas Ultraboost may appreciate the Scramjet’s similarly responsive midsole. However, the Scramjet has a lower heel-to-toe offset than the Ultraboost for a more natural foot position.

Go the distance in comfort

While excelling during speedwork, the Scramjet’s plush midsole still provides enough cushion for logging long run miles. The antimicrobial liner also helps keep feet fresh even in hot, sweaty conditions over miles.

Sleek style meets performance

On top of racing and training perks, the Scramjet boasts standout style with its sleek silhouette and color options. Despite the stylish look, these shoes maintain durability mile after mile when pushing the pace.

Test run first

Since fit varies based on foot shape, try the Scramjets on in-store first to get a feel for the snug midfoot lockdown and energetic cushioning. Ordering from a retailer with a good return policy can also ensure you get the right Scramjet fit.

Smooth transitions

The Scramjet’s outsole design encourages a smooth heel-to-toe transition so you can focus on achieving a fast turnover rather than fighting the shoe. This makes them ideal for tempo runs and speedwork requiring quick foot strikes.

Lightweight for performance

Ounce for ounce, the Scramjet sneakers provide robust performance without weighing you down. The breathable upper and flexible foam keep these shoes feeling featherlight, even on longer runs.

Neutral support

While best for neutral runners, the Scramjet’s external midfoot saddle and heel clip offer just enough structure to anchor landings before springing into the next stride. For moderate overpronators, they provide enough stability without correction.

All-around training partner

From marathon long runs to recovery jogs, the Scramjets have you covered training day in and day out. While best for speed, their responsive yet cushioned platform provides versatility across training paces and distances.

If you want a smooth, energetic ride for faster running, the Under Armour Scramjet sneakers deserve consideration. Their snappy cushioning and breathable locked-down fit encourage PRs whether you’re chasing a new mile time or pushing through a 5K. Give the Scramjets a test run and get ready to beat your personal best!

Available for both men and women

Sneakerheads everywhere have been buzzing about Under Armour’s latest performance running shoe – the Scramjet. This innovative sneaker packs a punch with cutting-edge features designed to give you an extra boost on your runs. With two iterations already released, the Scramjet sneakers have proven themselves as worthy competitors to similar shoes like the Adidas Ultraboost.

So why should the Scramjet be your next go-to running shoe? Let’s take a closer look at what makes these kicks so special.

Unmatched energy return

The hallmark of the Under Armour Scramjet is its unparalleled energy return, which helps propel you forward with each stride. This is accomplished through the use of Under Armour’s proprietary Charged foam in the midsole. This high-rebound foam absorbs impact and converts it into forward momentum, almost like your foot is on a trampoline. The Scramjet 2 and 3 have even more Charged foam than the original for maximum energy return.

In comparison tests, the Scramjet consistently outperformed competitors like the Ultraboost in terms of energy return. Less energy is lost with each foot strike, which can help reduce fatigue on long runs.

Ultra-responsive cushioning

In addition to the Charged foam, the Scramjet sneakers feature a full-length Micro G foam midsole. This provides a plush yet responsive cushioning that adapts to your foot’s individual needs. The dual-foam system works together to cushion impacts while also propelling you forward with springy responsiveness.

The Scramjet 3 has an updated midsole design that enhances stability without reducing cushioning. Small cutouts along the midsole edges maximize ground contact for smoother transitions. Underfoot comfort is paramount, even at higher speeds.

Breathable, flexible upper

A running shoe can have the best midsole technology, but it needs an upper that can match. The Scramjet delivers with a lightweight, minimal upper comprised of breathable mesh and strategically-placed support. The open mesh promotes air flow to keep your feet cool and dry even during sweaty summer runs.

Synthetic overlays provide structure and support around the midfoot without restricting flexibility. The Scramjet 2 introduced a new upper design with fewer overlays for enhanced breathability. It remains flexible enough for wide range of foot motions yet secure enough for faster paces.

Grippy traction

As an elite-level performance running shoe, the Scramjet employs a grippy rubber outsole to keep you stable even at faster speeds. Flex grooves along the forefoot promote a smooth roll-off while rubber lugs provide multi-directional traction. Whether you’re running straight ahead, changing direction, or pushing off up a hill, the outsole has you covered.

The Scramjet outsole also incorporates a responsive TPU piece to enhance energy return in the forefoot area. Together with the Charged midsole, your feet get double the bounce to turn each step into speed.

Versatile wearability

While designed for running, the Scramjet sneakers can also pull double duty as athletic lifestyle shoes. Their sporty yet stylish look pairs well with everything from gym clothes to jeans and a tee. For many, they’ve become the only sneaker they need – easily transitioning from workouts to everyday wear.

The Scramjets are offered in both men’s and women’s sizes with colorways ranging from bold brights to subtle neutrals. There’s an option for every taste and style preference. And with a reasonable $140 price tag, they deliver performance without breaking the bank.

Ideal for long miles or short bursts

With their responsive cushioning and turbo-charged energy return, Scramjet sneakers excel at both long distance runs and short bursts of speed. Some testers have reported improved 5K times after switching to the Scramjets while others praise their cushioning and support on half or full marathon distances.

The Scramjet 3 has a slightly lower drop (8mm versus 10mm) to encourage a more natural running stride. The smooth transitions and balanced cushioning help you maintain efficiency no matter the distance.

Rave reviews

Across the board, Under Armour Scramjet sneakers have earned rave reviews from both professional testers and everyday runners. They frequently rank high on lists of top running shoes thanks to their innovative midsole foam, breathable upper, and versatile traction.

Reviewers praise the “insane energy return” that helps them feel light on their feet and maintain speed even late into a run. The plush yet responsive cushioning also gets high marks for comfort without sacrificing ground feel.

For those looking to upgrade their current running shoes, the Scramjet line provides next-level performance perfect for PR chasing. As one reviewer put it, “My feet have never felt more alive!”

With game-changing technologies like Charged foam and two generations of fine-tuning, the Under Armour Scramjet sneakers represent the future of high-performance running shoes. They’ve already built up loyal following of fans impressed with their unbeatable energy return, cushioning, traction and lightweight comfort. If you’re looking for your new go-to shoe for speed work, long miles or everyday wear, the Scramjet should be at the top of your list.

Unique bold color options stand out

Runners and sneakerheads are always on the lookout for the next big thing in performance footwear. Under Armour has delivered just that with their Scramjet running shoes. Packed with innovative tech to give you a speedy advantage, the Scramjets also boast bold, head-turning style. Read on to see why these kicks deserve a spot in your rotation.

The Scramjet burst onto the scene a few years back as Under Armour’s answer to premium runners like the Adidas Ultraboost. With two iterations under their belts now, the Scramjets have proven they can hold their own against the top names in the game. The combination of responsive propulsion, cushioned comfort and standout looks checks all the boxes.

Energized by Charged foam

At the heart of the Scramjet’s speedy magic is Under Armour’s proprietary Charged foam midsole. This innovative material compressed energy from each footstrike and converts it into forward momentum to propel you along. It acts like a springboard, giving you that extra bounce to maintain cadence even as fatigue sets in.

The Scramjet 2 and 3 pack in even more of this high-rebound foam to maximize energy return. Less shock is absorbed by your legs and more gets channeled into your next stride.

Plush cushioning responds on the fly

Charged foam handles the propulsion, but Micro G foam provides plush cushioning that adapts to your footstrike. Together these two midsole materials provide the dual benefit of shock absorption and springy response. Mile after mile, your feet stay happy and energized.

Cutouts along the midsole edge on the Scramjet 3 maximize ground contact for smoother transitions. Cushioning remains robust but stability is enhanced for more control at varying paces.

Frees breathability with minimalist upper

The Scramjet’s lightweight mesh upper is optimized for running in warm weather. Strategically placed overlays provide structure while open mesh zones promote air flow to keep feet cool and dry on hot days. The Scramjet 2 minimized overlays even further for maximum breathability.

Despite the minimal coverage, reviewers praise the secure lockdown provided by the well-designed upper. It strikes the perfect balance of flexibility, support and ventilation.

Wild colorways stand out

While Under Armour has always been known for more understated color palettes, the Scramjet lineup breaks the mold with bold, wild styles. Vibrant neon hues, fiercesome animal prints, and unexpected color combos give these running shoes plenty of flair.

Men’s options range from citrus orange to pixelated camo to a bright green “Radioactive” pair that looks straight out of a comic book. Women’s styles include coral botanical prints, serene icy blues, and a butterfly motif, among others.

Whether you want your shoes to stand out or blend in, there are Scramjet colorways suited for every taste and personality. Their eye-catching looks have made them popular both on the track and off.

Traction and transitions

As a performance running shoe, the Scramjet employs a grippy yet flexible outsole to keep you stable across different speeds and surfaces. Segmented traction pads and flex grooves allow the foot to move naturally and flow smoothly from heel strike through toe-off.

In the forefoot, a thin TPU unit enhances energy return for more explosive toe-offs. Combined with the Charged foam, the outsole gives you double the bounce in every step.

Reviewers confirm the hype is real

Across the web, expert shoe testers and everyday runners agree the Scramjet delivers the advertised speedy performance. Words like “lightning fast,” “unstoppable” and “PR machine” are frequently used to describe the ride.

The energy return in particular garners praise, with testers reporting they feel “propelled forward” and their turnover seems almost “effortless” compared to other shoes. The cushioning provides soft landings without sacrificing ground feel.

For those looking to set new PRs or simply amp up their daily miles, the Scramjet gets rave reviews for providing that extra pep in your step mile after mile.

Take them the distance

With their tuned foam and traction, Scramjets excel at both short and long distances. The energetic pop is perfect for 5K to 10K races and speed work, while the cushioning supports half marathon distances and beyond.

The Scramjet 3 has a lower drop (8mm vs 10mm) for a more natural ride that maintains efficiency across any distance. Testers have noted the smooth, balanced ride seems to “protect my legs for the long haul.”

Between the energetic lift-off, soft landings and snappy toe-offs, the Scramjets will keep you cruising comfortably no matter how far you roam. Mile 15 feels as fresh as mile 1.

For runners demanding the best of speed and comfort, the Under Armour Scramjet range hits that sweet spot. With wild colors to choose from and performance that lives up to the hype, these shoes will inject some bold new energy into your running rotation.

Designed to rival Adidas Ultraboost shoes

The running shoe market is filled with options these days, but one emerging challenger brand has been making serious waves – Under Armour. Specifically, their Scramjet model was designed to compete directly with the popular Adidas Ultraboost. After two iterations, the Scramjets have proven they have what it takes to hang with the top dogs.

Packed with proprietary innovations and sleek, modern styling, the Scramjets represent an exciting new choice for runners demanding top-tier performance. Here’s a closer look at how these shoes rival the Ultraboost and why they deserve a spot in your rotation.

Charged foam fuels your stride

The Scramjet’s signature technology is Under Armour’s proprietary Charged foam midsole. This high-rebound material absorbs impact and immediately returns that energy to propel you forward with each step. It creates a slingshot effect for your foot, maintaining momentum even as you fatigue.

In comparison testing against the Ultraboost, the Scramjet posted better energy return numbers thanks to the Charged foam. Less energy gets lost with each footstrike, helping you feel lighter on your feet for longer.

Plush yet responsive cushioning

While the Charged foam provides the bounce, Micro G foam handles cushioning duties with its adaptive, responsive foam. It quickly pads impacts then springs back for smooth transitions. Together, the two foams work in harmony to keep your feet feeling fresh.

The Scramjet 3 tweaked the midsole design to enhance stability without sacrificing the plush feel. Precise laser cut-outs provide the ideal balance of cushion and support.

Sleek style inspired by the Ultraboost

It’s clear when looking at the Scramjet’s streamlined silhouette that design cues were taken from the wildly popular Ultraboost. The foot-hugging upper, pillowy midsole and grippy Continental rubber outsole all share similarities with the Adidas model.

But the Scramjet puts its own original spin on things with unique patterns, color schemes and branding elements. The result is a shoe that looks modern, energetic and distinctive without feeling like a copycat.

Lightweight, breathable upper

While taking notes from the Ultraboost’s upper design, the Scramjet optimized breathability by using a minimal single layer mesh. This creates a sock-like fit that flexes naturally with the foot’s movement. Overlays are strategically placed for structure and support only where needed.

The open construction allows maximum airflow to keep feet cool and comfortable, even on hot summer runs. Reviewers consistently praise the ventilation and foot-conforming comfort.

Grip and propulsion in the outsole

The outsole is another area where the Scramjet matches up closely with the Ultraboost formula. Segmented rubber pads in the heel and forefoot provide reliable traction while allowing natural flex. The grip stands up to both straight-line runs and tricky changes of direction.

In the forefoot, a thin TPU unit adds extra bounce to each toe-off. Combined with the Charged foam, it creates responsive propulsion to keep turnover high. Your feet feel energized and light across all distances.

On the road and in reviews, the Scramjet goes toe-to-toe with the Ultraboost, proving itself a formidable rival. For those seeking an exciting new alternative with all the performance tech of a true competitor, the Scramjet delivers the goods.

Typically retail around $140 USD

Runners are always on the hunt for that perfect pair of shoes to bring their performance to the next level. Under Armour threw its hat into the premium running shoe ring with the launch of the Scramjet model. Priced to compete with marquee names like the Adidas Ultraboost, the Scramjets deliver serious tech and style without breaking the bank.

After two well-received iterations, the Scramjet has proven itself as a budget-friendly option stacked with pro-level features. Here’s a closer look at why this relative newcomer deserves consideration alongside more established players in the $140 price range.

Loaded with energy-returning Charged foam

The Scramjet’s claim to fame is its ample use of Charged cushioning foam in the midsole. This proprietary high-rebound material gives your stride an energized bounce, propelling you forward with each step. It takes the impact energy from footstrike and recycles it into momentum.

More Charged foam is packed into each successive model – the Scramjet 3 has the most yet. Reviewers rave about the “trampoline effect” it gives, allowing you to turn over faster with less exertion.

Plush Micro G foam adapts on demand

While the Charged foam handles propulsion, Micro G foam provides an adaptive cushioning experience. It quickly pads impacts then rebounds for smooth transitions. This dual-foam system works synergistically to keep feet happy across long distances.

Laser-cut perforations along the Scramjet 3’s edges optimize stability without losing the plush feel. Padding remains robust while transitions become more seamless.

Premium features at a palatable price

Considering its impressive energy return, cushioning, traction and lightweight comfort, the Scramjet holds its own against premium offerings from other top athletic brands. Yet it comes in around $140 – significantly less than shoes like the Ultraboost.

For runners unwilling to fork over $180 but wanting high-end performance, the Scramjet line hits that sweet spot. It brings many of the same technologies in a well-built package for less. Reviewers call them a “steal” and “seriously underpriced for what you get.”

Breathable, foot-hugging upper

The Scramjet borrows design cues from the Ultraboost’s flexible upper, but uses fewer overlays for enhanced ventilation. Strategically placed support provides a secure fit, while open mesh zones let air flow freely into the shoe.

Many testers comment on the “sock-like comfort” and cool, dry feel even on extended summer runs. For the price, it’s impressive how dialed the upper is.

Grippy outsole inspired by Continental rubber

Under Armour opted for its own rubber compound rather than licensing Continental rubber like adidas. But the Scramjet’s outsole still provides excellent traction thanks to zonal tread patterns and targeted flex grooves.

In the forefoot, a thin TPU layer adds extra bounce to each propulsive toe-off. Combined with the Charged foam, it gives you responsive energy return right where you need it.

For runners seeking performance and innovation on a budget, the Scramjet punches well above its weight class. It goes toe-to-toe with premium models nearly $40 more – and often comes out on top.

Consider the Scramjets for your next pair of performance running shoes

The running shoe marketplace is filled with options these days, but a relative newcomer that deserves consideration is the Under Armour Scramjet. Designed to compete with established favorites like the Adidas Ultraboost, the Scramjets pack innovative tech into an eye-catching package perfect for logging fast miles.

Now two iterations deep, the Scramjet lineage has carved out a niche for itself among runners seeking propulsive energy return, cushioned comfort and bold style. Before buying your next pair, make sure to check out what the Scramjets bring to the table.

Charged foam fuels your stride

The Scramjet’s signature midsole foam is Charged, Under Armour’s proprietary responsive cushioning material. It compresses on impact then immediately rebounds, recycling energy into forward momentum to keep your turnover quick and snappy.

Testers consistently rate the “springy” Charged foam above competitors for energy return. Less impact is lost with each stride, so your legs stay fresher longer into a run.

Plush Micro G foam enhances comfort

While the Charged foam provides the energetic lift, Micro G foam handles step-in comfort and shock absorption. Its adaptive construction cushions impacts then quickly rebounds for smooth transitions.

The dual-foam compound works synergistically to protect feet from shock while propelling them forward. Reviewers love the “soft yet responsive” ride.

Traction and transitions

The Scramjet’s grippy outsole utilizes zonal rubber pads and flex grooves to keep you stable across varying speeds and surfaces. Segmented lugs in key zones provide multi-directional traction for straight-line runs or tricky maneuvers.

In the forefoot, a thin TPU plate amplifies energy return for snappy toe-offs. Combined with the bouncy Charged foam, it gives you double the pep in your step.

Breathable, foot-hugging upper

A seamless single layer mesh upper provides a sock-like fit with zonal support only where needed. Open airflow zones keep the foot environment cool and dry even at high intensities or warm temps.

Despite the minimalist design, testers praise the secured lockdown over the midfoot. The upper strikes the ideal balance between flexibility and foot-conforming support.

Impressive performance for the price

Considering its energy return, cushioning, traction and lightweight comfort, the Scramjet holds its own against top-tier offerings from other brands. Yet it comes in around just $140 – over $40 less than premium competitors.

For runners seeking high-end features on a budget, the Scramjet line hits that sweet spot. You get the performance without overpaying.

Before locking in your next pair, be sure to try on the Scramjets. You may find the ideal blend of energized propulsion, plush comfort and sleek style in a package that won’t break the bank.
