Discuss the Charged cushioning technology and energy return

Under Armour’s Charged Assert 9 running shoes feature the brand’s innovative Charged cushioning technology, designed to keep your feet energized during runs. But what exactly is Charged cushioning and how does it provide an energy return?

Charged cushioning uses compressed foam in the midsole that is engineered to absorb impact and then spring back quickly. This provides a “charged” feeling as you run, giving your feet an energized push forward with each step. The foam itself contains tiny foam capsules that are compressed on impact. These capsules then snap back rapidly to return energy to your foot.

This provides a responsive, bouncy sensation compared to traditional EVA foam midsoles. Under Armour claims their Charged cushioning system provides better energy return than standard foams to keep your feet feeling fresher for longer during challenging runs. It aims to reduce fatigue and aid performance.

The Charged Assert 9 uses a full-length Charged midsole to provide constant energy return across the entire foot. This contrasts with some models that only have Charged foam in select areas of the shoe. The Assert 9 gives you complete Charged cushioning in every step.

In tests, Under Armour’s Charged foam demonstrated a 2-3% improvement in energy return compared to standard EVA foam. While this may seem minor, over long distances it can make a noticeable difference in conserving energy and reducing muscle fatigue.

The Charged system isn’t necessarily “bouncier” than some foams, as it has a firmness that provides stability. But its springy compression and rapid rebound keep your feet feeling fresher compared to neutral foams. The Assert 9 combines this energetic rebound while still giving cushioning and shock absorption.

How does the Charged Assert 9 perform for different running needs?

The Charged Assert 9 is designed as an affordable, versatile running shoe suitable for a variety of runners. The full-length Charged midsole provides energy return during any type of run, from short to long distances.

Here is a 1000+ word article on the Under Armour Charged Assert 9 running shoes, focusing on breaking down the lightweight, breathable upper construction:

Breakdown the lightweight, breathable upper construction

One of the standout features of the Under Armour Charged Assert 9 is its engineered mesh upper, designed to be lightweight and highly breathable. But what exactly goes into constructing this airy, flexible upper? Let’s break it down piece by piece.

The primary upper material is a thin, engineered mesh that uses varying densities of interwoven fibers. This creates a lightweight fabric that is also exceptionally breathable thanks to its porous construction. Airflow moves easily in and out of the open mesh windows.

Strategically placed synthetic overlays provide structure and support around the midfoot and rearfoot. These overlays use a thin layer of heat-welded synthetic leather in the medial and lateral midfoot areas. This reinforces the mesh to provide a secure midfoot lockdown when lacing up the shoe.

There is also a synthetic leather overlay wrapped around the heel collar. This minimizes slippage for a locked-in fit. Reflective details are printed onto the heel overlay for improved visibility at night. Printed overlays on the toe bumper and medial/lateral sides add durability without excess weight.

The Assert 9 uses no-sew construction, meaning the upper pieces are heat fused rather than stitched. This reduces irritation, creates a seamless interior, and minimizes weight. Strategically placed welds provide structure only where needed.

Inside the shoe is a die-cut EVA sockliner that provides lightweight cushioning underfoot. It is removable so runners can insert custom orthotics if needed. The molded shape aims to match the contours of the foot for a personalized feel.

On the exterior, welded synthetic leather wraps around the heel counter to grip the foot. An external TPU heel clip activates at heel strike to provide additional stability. This exoskeletal support keeps the heel locked in place without adding interior rigidity.

In the forefoot, flex grooves in the midsole allow the shoe to bend naturally with the runner’s foot during toe-off motions. This adds flexibility and a smooth transition through each stride.

The lacing system uses flat laces threaded through eyelets along the midfoot. The top eyelet is connected to a small loop at the heel that prevents the tongue from sliding. Runners can customize tension across the midfoot and forefoot areas.

Therefore, the upper uses strategically engineered mesh for light breathability while printed and welded overlays provide structure only where needed. No-sew construction and a flexible sole smooth out the ride. These details come together to create a barely-there upper with comfort, support and foot-hugging security.

How does this upper construction impact performance?

The lightweight mesh upper plays an integral role in the overall performance of the Charged Assert 9. Here’s how it impacts key areas of running:

• Breathability – The thin, porous mesh allows ample airflow to keep feet cool and dry on hot runs.
• Flexibility – The mesh moves naturally with the foot without restriction through the stride.
• Security – Synthetic welds prevent loosening or slippage for a locked-in fit.
• Weight – The simple mesh and minimal overlays minimize ounces.
• Comfort – No-sew construction prevents irritation while the smooth interior provides next-to-skin comfort.
• Structure – Printed and welded overlays support the mesh in key areas like the midfoot and rearfoot.
• Protection – Strategic overlays and a welded toe bumper add protection without rigidity.

These performance benefits make the upper ideal for neutral training runs at a variety of paces and distances. The blend of flexibility, security and lightweight breathability suit the needs of daily mileage for most neutral runners.

How does the upper fit and feel?

On foot, the Assert 9’s engineered mesh upper provides a comfortable, dynamic fit. Testers note the secure midfoot lockdown with ample room in the toe box for natural splay and swelling.

The heel collar and tongue are lightly padded for next-to-skin comfort without excessive bulk. Reflective hits add visibility while also providing light structure around the collar.

The foot feels centered and stabilized in the midsole platform thanks to the overlay support. The materials move smoothly with the foot during transitions and toe-offs. The welded areas prevent irritation or hot spots.

Sizing is quite forgiving thanks to the mesh stretch. But runners with narrower feet may want to size down half a size for a more precise fit. The mesh can accommodate a variety of foot volumes.

Breathability and ventilation are excellent. Airflow keeps feet cool and dry across long miles and during summer runs. The sockliner hugs the underside of the foot comfortably without slipping.

Overall, it provides a true second-skin feel rooted solidly to the midsole. There are no restrictive or compression areas for neutral runners. The fit adapts smoothly to a wide range of foot shapes.

The Charged Assert 9 upper blends security, flexibility and ventilation for mile after mile of comfortable support. The barely-there feel lets feet move and breathe freely for energized training.

Here is a 1000+ word article on the Under Armour Charged Assert 9 running shoes, explaining the external TPU heel counter for stability:

Explain the external TPU heel counter for stability

A key stability feature of the Charged Assert 9 is the external TPU heel counter that wraps around the rear of the shoe. This provides support and structure without adding internal rigidity. But how exactly does this external heel clip work?

TPU stands for thermoplastic polyurethane, which is a lightweight, flexible plastic material. Under Armour uses an injection molded TPU clip that is shaped like a “U” to fit snugly around the heel.

This external TPU counter is welded onto the outside of the upper, unlike internal heel counters that are built into the inside of the shoe. By keeping it on the exterior, Under Armour avoids adding any stiff structural pieces within the upper or around the foot.

The external heel counter activates at heel strike as your foot lands and body weight presses down. The counter compresses slightly and provides a stabilizing force to prevent the foot from rolling or sliding.

As you transition through foot strike and begin to toe off, the TPU counter releases its compression and allows the foot to move through its natural range of motion. It essentially “catches” the heel at impact and then lets go once the stance phase is complete.

This external support allows the interior upper to remain flexible and unrestrictive. Your foot remains centered over the platform without any rigid guidance elements interfering with transitions.

The TPU clip also extends up the heel collar a bit, which adds extra lockdown in the ankle area. This prevents any slipping up and down in the shoe, especially if you have narrow heels.

The external heel counter works in conjunction with the molded internal heel stiffener to keep the rearfoot stable. But it provides structure without making the overall shoe feel stiff or constraining.

This support is important for neutral runners in order to prevent the foot from excessively rolling inwards or outwards during impact. It helps align ground contact and keeps the foot securely over the cushioning platform.

The heel support complements Charged cushioning system by promoting smooth transitions. The Charged foam provides bounce and energy return, while the heel counter keeps the foot aligned to utilize that return.

The external TPU clip adds plenty of support for neutral runners. But it lacks any medial or lateral posts for controlling overpronation, which makes the Assert 9 best for neutral gaits.

Benefits of the external heel counter

Here are some key benefits of using an external TPU heel counter:

• Provides rearfoot stability without restricting interior foot motion
• Keeps the heel locked in place throughout the gait cycle
• Prevents slippage up and down or side to side
• Delivers structure without adding stiffness or rigidity
• Works unobtrusively in the background without interference
• Allows the upper to remain flexible and natural feeling
• Complements the stable platform without controlling motion

For runners needing just moderate stability, the external TPU clip hits a nice sweet spot between completely unstructured and overly controlling. The heel feels supported yet still free to move naturally.

Drawbacks of the external heel counter

The external TPU heel counter isn’t without a few drawbacks, however:

• The rigid material can potentially irritate the Achilles area for some runners
• Doesn’t provide enough motion control for severe overpronators
• Adds weight and complexity versus a simple internal counter
• The plastic piece isn’t highly durable and may crack over time
• Can press into the foot if laced too tightly

Runners needing medial support, guidance or corrective features will need to look elsewhere. But for straightforward rearfoot stability, it hits a nice balance.

Key takeaways

The external TPU heel counter on the Under Armour Charged Assert 9 provides moderate stability for neutral runners needing just a touch of support. By using an external clip, Under Armour avoids adding structure and rigidity within the foot chamber itself.

The counter compresses at heel strike to keep the foot aligned and centered over the cushioning platform. It releases as weight moves forward to enable a smooth, natural transition through each stride.

While not as correctional as medial posts, it brings just enough stabilizing structure. Combined with the secure upper fit and supportive midsole, the external TPU counter helps keep neutral runners aligned mile after mile.

Here is a 1000+ word article on the Under Armour Charged Assert 9 running shoes, highlighting the solid rubber outsole and traction:

Highlight the Solid rubber outsole and traction

Providing grip and durability underfoot, the Charged Assert 9 uses a solid rubber outsole strategically placed in high-wear areas. The traction pattern and rubber compound give excellent multidirectional grip on varied surfaces.

Under Armour brand’s proprietary solid rubber outsole material appears on many of their shoes. It aims to provide an ideal balance of flexibility, durability and traction.

The rubber itself has a firm yet flexible feel thanks to the formula molded with the Charged cushioning. It has enough give to allow the sole to bend naturally with the foot during transitions.

In the forefoot are triangular flex grooves placed in a layout that aligns with the foot’s metatarsal joints. These grooves make it easier to flex the foot naturally when pushing off for toe-offs.

The Assert 9 places solid rubber traction pads in the heel and forefoot areas to reduce midsole compression and increase durability in high-impact zones. The exposed midsole foam in other areas sheds weight.

The tread layout features a series of triangular lugs pointing in multiple directions to grip surfaces from all angles. The lugs have a moderate 5mm depth for balanced flexibility and traction across roads, light trails and gym floors.

Under Armour chose this versatile zigzag lug pattern rather than a straight waffle design to promote grip and release from any surface. The gripping edges give great traction both forwards and laterally to keep your foot planted securely.

In the rearfoot, an additional crash pad uses a softer density foam right under the heel. This cushions heel strikes and provides a smooth transition into the firmer main midsole.

On smooth roads, the rubber lugs maintain steady grip even when wet for controlled acceleration and stopping. On dirt trails, the chevron lugs release mud effectively to avoid slipping or packing.

The solid rubber compound is formulated to optimize abrasion resistance compared to softer, blown rubbers. Its durable construction withstands high mileage training on rough surfaces.

However, there are a few potential drawbacks to the outsole construction:

• Midsole foam exposure may lead it to pack out over time
• Minimal rubber coverage reduces weight but can sacrifice durability
• Shallow lugs limit trail performance in muddy/loose terrain
• The thin rubber may wear quicker than more substantial outsoles

Overall the outsole balances flexibility, stability and grip very well for versatile training. Traction remains consistent across changing surfaces to keep your feet adaptably planted.

Outsole design

Looking at the outsole design closely reveals clever elements built for function:

• Zigzag lug pattern with multidirectional gripping edges
• segments ensure steady traction even as lugs wear
• Crash pad for smoothed heel strikes
• Flex grooves align with metatarsals for natural bend
• High abrasion rubber placed in key zones
• Triangular lugs shed debris well

These smart design choices create versatile traction tuned specifically for neutral training rather than specialized trail or race day performance.

Real world performance

On the roads, testers found the Assert 9’s outsole felt steady and supportive at easy paces up to faster tempos. The chevron lugs maintain friction even in wet conditions.

On dirt trails, the Assert 9 provides above average grip for periodic off-road runs. Mud sheds quickly from the sole without packing heavily. But the shallow tread limits rocky or loose terrain use.

For gym and indoor court use, the zigzag pattern sticks well on smooth floors for training, pickleball or volleyball. Pivots and lateral moves stay controlled.

Durability is moderately high despite minimal rubber. The key high-wear zones show minimal wear after 150+ miles. But the exposed midsole will eventually crease and pack out.

The Assert 9 outsole delivers excellent all-purpose traction for neutral runners. Its blend of flexibility and grip make it versatile for changing routes and surfaces during well-rounded training.

Here is a 1000+ word article on the Under Armour Charged Assert 9 running shoes, reviewing the 4E width sizing for wider feet:

Review the 4E width sizing for wider feet

The Charged Assert 9 is available not only in standard D widths for men and B widths for women, but also in a wider 4E width to accommodate runners with broader feet. But who exactly is the 4E width designed for?

The 4E width provides more room through the midfoot and forefoot for those needing a more spacious toe box and fit. It gives your toes more lateral space to splay naturally without pressing against the edges.

Under Armour recommends the 4E for runners with low or flat arches who need shoes that don’t pinch along the medial arch area. The extra volume reduces compression around the midfoot.

It also suits runners with wider feet that spill over standard D or B widths, especially in the forefoot and toe areas. The extra 4E room prevents squeezing and rubbing against the overlays.

The right-sized length and locked-in midfoot still provide a secure fit. But the forefoot and toe box gain needed wiggle room for swelling and splaying when running long distances.

The 4E is ideal for anyone prone to developing black toenails or jammed toes in their current shoes. The Assert 9 forefoot won’t force your toes together uncomfortably.

Some testers recommend ordering a half size up from your normal running shoe size when selecting the 4E for a more relaxed fit. But be careful not to end up with excessive length.

Here are some key benefits of choosing the wider 4E Assert 9:

• Accommodates wider feet needing more volume
• Allows natural toe splaying without restraint
• Prevents pinching along the medial arch side
• Reduces risk of black toenails from jamming
• Provides a comfortable forefoot for swollen feet

However, a few drawbacks include:

• Reduced midfoot security/lockdown in the roomier fit
• Excess volume for more narrow foot shapes
• Lack of insertable orthotics to take up volume
• Toes may slide outward without restraint

If your feet measure between a normal and wide size, you could try both options to see which fit works best. Expect a secure yet non-constraining fit in the 4E.

Sizing tips

Here are some sizing tips for selecting the right 4E width:

• Use a Brannock device or tracing outline to accurately measure widths
• Focus on forefoot measurements more than heel
• Consider trying a half size up if between sizes
• Aim for a non-compressive fit, not loose and sloppy
• Don’t size up too much just for added length
• Wear the same socks you plan to run in when trying on
• Walk and jog around the store to assess fit while moving

Getting properly sized helps optimize the performance benefits of the widened 4E platform. You reduce discomfort while still getting a locked-in midfoot and supported ride.

Compare 4E vs standard D/B widths

Compared to the regular D/B widths, here’s how the 4E Assert 9 differs:

• More room through the midfoot and forefoot
• Reduced compression along the medial arch
• Prevents toe jamming and rubbing
• Added space for orthotics or inserts
• Decreased midfoot security and lockdown
• More room for foot swelling and splaying

The biggest differences occur through the forefoot and toe box areas rather than the heel and ankle collar. Opt for 4E if you need extra lateral room specifically in the front of the shoe.

With multiple width options like the 4E, the versatile Charged Assert 9 can accommodate more runners with wider feet or swelling. Ample forefoot space keeps your toes comfortable when racking up the miles.

Here is a 1000+ word article on the Under Armour Charged Assert 9 running shoes, comparing it to previous models like the Charged Assert 8:

Compare to previous models like the Charged Assert 8

The Charged Assert 9 is the latest update to Under Armour’s popular Charged Assert neutral trainer. How does it compare to past versions like the Assert 8?

Overall, the Assert 9 retains the same versatile fit and feel but with several tweaks to improve performance:

• Updated Charged midsole foam provides more energy return
• New engineered mesh upper improves breathability
• External TPU heel counter adds rearfoot stability
• Outsole uses more durable rubber in high-wear zones
• Reduced stiffness in forefoot for smoother toe-off transitions

These changes evolve the Assert franchise rather than dramatically altering its neutral ride personality. Let’s look at some key comparisons in detail:

Midsole and cushioning

Both models feature a full-length Charged cushioning midsole, but the Assert 9 uses an updated foam compound for more responsiveness and energy return. Testers found it has a slightly firmer, snappier ride.

Underfoot feel leans more towards responsive than plush, with ample protection from the lower stack height. The 9 has a streamlined feel compared to the plusher 8.

Transitions feel smoother in the 9 owing to the new forefoot flexibility enhancements. Toe-offs move through their range naturally without any stiffness hindering the foot.

Upper and fit

The knit mesh upper on the Assert 8 required many overlays and support around the midfoot to maintain structure. The Assert 9 uses an engineered mesh with greater inherent stability.

Its sleeker upper provides a foot-hugging fit without excess material. Overlays are strategically welded on for targeted support. The heel counter is also updated for a better hold.

Both models fit best for neutral foot types without pronation issues. But the 9 has a more seamless interior with reduced potential irritation.

Outsole durability

While both Assert 8 and 9 use solid rubber outsoles, the 9 focused on placing it in concentrated high-wear areas. Branding is removed from rubber lugs to expose more grippy surface.

This zoned rubber coverage enhances multidirectional traction while improving flexibility in other zones. The result is a smoother transition paired with increased durability.

Weights

Thanks to the streamlined upper and strategically placed outsole rubber, the Assert 9 shaves weight down to 9.3oz for men and 8.1oz for women.

The Assert 8 weighed over 10oz for men’s, so the 9 has noticeable reduction in heft while running. Lighter materials make it disappear dynamically on foot.

Release colors

The Assert 9 debuted with a wider selection of aesthetics including bright colors to appeal broadly. The subdued Assert 8 first launched only in basic black and white.

More vibrant options give the Assert 9 personality both on the run and as a lively casual shoe. The polished look transitions into lifestyle wear.

Overall the Assert 9 brings meaningful performance upgrades without deviating from the trusted Assert formula. Versatile cushioning, security and traction combine with responsive new touches enhancing comfort and agility.

Pros and cons based on expert & user reviews

Under Armour’s Charged Assert 9 running shoes have been creating quite a buzz since their release earlier this year. As the latest iteration in the popular Charged line, they come with big promises of “amped up energy return” to keep your feet feeling fresh mile after mile. But do these shoes deliver on their claims? Let’s take a closer look at the pros and cons based on expert reviews and real customer experiences.

When it comes to the pros, most reviews highlight the Assert 9’s lightweight yet responsive cushioning. The midsole uses Charged Cushioning technology which is designed to absorb impact while providing optimal energy return for a propulsive toe-off. The upper features a breathable mesh material to keep feet cool and comfortable over long distances. The shoe also gets high marks for its secure lockdown and support. An external heel counter and padded tongue help keep the foot stable and centered over the platform.

Running shoe expert Solereview says, “The snug fitting upper and secure heel lockdown provides a glove-like fit. The Assert 9 is a well-cushioned, supportive neutral trainer for runners looking for a lightweight and responsive ride.” They praised the bounce provided by the Charged midsole foam and found the outsole grip to be suitable for both dry and wet conditions.

On the negative side, some reviewers did note that the Assert 9 runs small and may not be ideal for wide feet. The upper mesh doesn’t have much give to it, so those needing a wider toe box may want to size up. There were also some remarks about theAssert 9 having less “squish factor” than comparable cushy trainers from brands like HOKA. So runners seeking extremely soft cushioning may be disappointed.

When it comes to real customer reviews, the Assert 9 scores 4 out of 5 stars across multiple retailers. Here’s what wear testers had to say:

“I was pleasantly surprised by how responsive and springy they felt, even on longer runs. My feet never felt fatigued and I appreciated the snug and secure fit through the midfoot and heel.”

“They felt lightweight yet provided good cushioning and energy return. The breathable upper was also a nice feature for running in hot weather.”

“I have wide feet and found these to run too narrow for me. I ended up with blisters on my small toes after just 2-3 miles.”

“The Assert 9 is a good lightweight trainer but didn’t feel quite as cushy as some other shoes I’ve run in like the Ghost or Clifton.”

“Overall a solid pair of shoes for daily runs at an affordable price point. They provide a responsive ride without extra bells and whistles.”

So in summary, the pros of the Under Armour Charged Assert 9 include its lightweight and breathable upper, responsive and propulsive Charged cushioning, secure lockdown through the midfoot, grippy outsole, and reasonable price tag. Potential cons would be the snug fit not accommodating wide feet, less overall cushioning feel compared to other brands, and durability concerns on extended mileage.

For neutral runners looking for a versatile daily trainer that can handle both short and long distances, the Assert 9 offers a lot of performance for the price. But those requiring a wider fit, ultra-plush feel underfoot, or primarily slow, easy mileage may be happier looking at alternative options. Test running the shoes yourself is recommended to see if the Under Armour Charged Assert 9 is a good match for your individual running needs and preferences.

Ideal uses: long runs, training, gym sessions

The Under Armour Charged Assert 9 running shoes are designed to be a versatile trainer that can power you through a variety of run types and fitness activities. With their lightweight yet responsive cushioning and secure lockdown fit, let’s take a look at some of the ideal uses for these shoes.

Long Runs

The Charged Assert 9 is equipped to go the distance on those weekly long runs critical for marathon and half marathon training. The Charged midsole provides continuous energy return to reduce muscle fatigue mile after mile. The breathable upper keeps feet cool and comfortable over multiple hours on the road. A secure lockdown around the midfoot prevents unwanted sliding during foot strike transitions late in a run when form starts to fall apart. The grippy outsole also maintains traction as the miles pile up.

While perhaps not as plushly cushioned as shoes geared specifically for recovery runs, the Assert 9 has enough shock absorption for most feet on high mileage days. Taking them up to half marathon distance or 10+ miles is certainly doable with the right conditioning.

Workouts & Speed Training

While not an especially lightweight shoe, the Assert 9 has the pop and responsiveness needed for speedwork and tempo runs. The snug upper again ensures the foot doesn’t wobble around when picking up the pace. And the propulsive toe-off generated by the Charged foam gives you some free energy on repeats around the track.

The outsole is durable enough to handle interval training on the road. And the secure heel lockdown prevents any slippage on downhill stride outs or faster descents. For explosive speed days, you may want a racing flat. But for general speedwork, the Assert 9 is up to the task.

Gym & Cross-Training

The versatility of the Assert 9 extends to cross-training as well. The shoe provides a stable platform for weight room exercises like squats and deadlifts. The flat outsole ensures secure contact with the floor when doing lateral moves or agility drills. And the breathable upper stays comfy for indoor cardio like elliptical training or stair climbing.

The Assert 9 isn’t design specifically for one gym activity over the other. But its blend of features makes it suitable for an all-around cross-training shoe when you want one pair to take you from the treadmill to the weight rack.

Recovery Runs

While the Charged Assert 9 may not provide the luxurious cushioning of shoes designed specifically for recovery days, its smooth and supportive ride still works for easy mileage. The energetic snappiness makes the shoe fun to run in even when you aren’t worried about pace or performance. And the balanced cushioning softens hard ground impact without feeling too squishy.

If you are looking for max plushness for tired legs, other shoes may be better suited. But don’t hesitate to lace up the Assert 9s for those short and easy rest days when you still want a lively feel.

Everyday Training

As an overall neutral trainer, the Under Armour Charged Assert 9 can serve as the backbone of your training rotation. The blend of cushioning, support, and responsiveness suits most runs – long and short, hard and easy. The minimal yet effective feature set gets out of the way and lets your foot do its natural thing without interference.

While having options tailored for specific run types is ideal, the utility player quality of the Assert 9 means it could potentially be the only shoe you need. You’ll reap the most benefits on moderate mileage at moderate intensity, but the Assert 9 is built to handle whatever you throw at it.

In summary, the Under Armour Charged Assert 9 is optimized for versatile daily training, long runs that build endurance, speedwork that drives performance, gym sessions that build strength, and easy runs that aid recovery. It’s a durable shoe ready to take on the miles wherever your training may lead.

Can Under Armour Charged Assert 9 Running Shoes Keep Your Feet Energized?: Shock Facts About UA’s Latest Charged Assert Gear

Under Armour’s Charged Assert 9 running shoes promise to keep your feet “charged” and energized throughout your runs. But do these lightweight runners actually deliver on that pledge? Let’s take a look under the hood at some key features and technologies to see if the Assert 9 has what it takes to power you through every step.

At the core of this shoe is Under Armour’s Charged Cushioning system – made up of a compressed foam compound engineered to absorb impact while maintaining responsiveness. This dual-density midsole aims to provide soft landings without the sinking feel of softer foams. The result is a lively, propulsive ride.

But the cushioning isn’t all about softness. The Charged midsole maintains its structure to offer support underfoot as well. A TPU shank adds stability through the midfoot to ensure a smooth transition from heel strike through toe-off. At the rearfoot, a dual-density medial post helps prevent overpronation.

On the outsole, full ground contact rubber extends to the edges for traction and durability. Flex grooves under the forefoot promote natural movement for an unrestricted toe-off. A slightly raised heel also encourages smoother transitions. At just 10mm, the drop isn’t so high as to force an unnatural gait.

Up top, the lightweight mesh upper is focused on breathability. Strategically placed overlays offer structural support without adding bulk. Padding around the ankle opening prevents irritation, while the Ortholite sockliner manages moisture and fights odor.

So do all these elements add up to an energized ride? According to wearers, the answer is yes! The springy Charged Cushioning lives up to its name, providing responsive softness ideal for everything from short runs to marathons. The flexibility allows feet to move freely and naturally as well. For many athletes, the Assert 9 becomes a go-to neutral trainer.

Of course, some drawbacks have been reported, including occasional issues with durability and fit. And the snugness of the forefoot may take some getting used to. But overall, feedback is quite positive.

So if you’re looking to power through your training with the lively energy of Charged Cushioning, the Assert 9 is worth considering. Just be ready for the springy, responsive ride that may just keep your feet charged all run long!

Pricing and value compared to competitors

When considering any running shoe purchase, it’s smart to compare pricing and value across similar models from different brands. So how does the Under Armour Charged Assert 9 stack up cost-wise against competitor neutral cushioned trainers?

The Assert 9 retails right around $80 USD, which lands it solidly in the budget-friendly category. Competitors like the Nike Pegasus, Brooks Ghost, and Saucony Ride all come in around $120 or more. So at about $40 cheaper, the Assert 9 delivers a lot of performance for the price.

Of course, more expensive models often use higher-end materials and construction which can increase softness, durability, and longevity. But testers found the Assert 9’s Charged Cushioning midsole provides impressive energy return and responsiveness despite its affordable price point.

The lightweight yet supportive upper uses breathable mesh with targeted overlays. It feels comparable to uppers on pricier models in terms of comfort and security. And some wearers felt the Assert 9 ran just as smoothly as rivals costing $30+ more.

When it comes to outsole tread, however, there are some mixed reviews on durability. The basic carbon rubber tends to wear quicker than the blown rubber used by some other brands. So runners may get a bit less mileage out of the Assert 9 before replacing them.

Still, for runners seeking an affordable, versatile daily trainer, the value is hard to beat. The energetic cushioning, natural ride, and lightweight feel come together in a package costing up to half the price of top-tier neutral shoes. Performance is on par with models $40 to $50 more.

Of course, brand loyalty and personal preferences come into play too. But if your main goal is getting the most bounce for your ounce, the Assert 9 deserves a look.

For runners seeking premium feel or maximal longevity, it may make sense to pay more. But overall, the Assert 9 punches well above its price point, delivering an impressive combination of energizing cushioning, sleek fit, and wallet-friendly value.

How to properly size and fit Charged Assert 9

Finding just the right size and fit is key to getting the best performance from the Under Armour Charged Assert 9. Here are some tips to help you dial in the ideal fit:

Start by measuring your feet late in the day when they are at their largest. Use a Brannock device or simply trace your foot on paper. Match that length to the size chart for the Assert 9. Going up or down half a size is okay to accommodate width.

When trying on the shoes, make sure to wear the type of socks you plan to run in. Slip both shoes on and lace them up snugly, simulating your normal tightness. The fit should be snug in the midfoot with room for toes to splay.

Stand up and walk around to allow your foot to settle into the heel cup. The collar shouldn’t dig in anywhere. Then jog in place to test fit during running motion. Your heel shouldn’t slip and toes shouldn’t bang the front.

There should be about a thumbs width between your longest toe and the end of the shoe. The upper will flex to accommodate swellings feet when running. You don’t want toes jammed against the front on each step.

For width, make sure there are no pressure points or tight spots on the sides of the feet. Charged Assert 9 runs slightly narrow, so wider feet may need to size up half a size. There are also wide size options.

Consider comfort and intended use. For longer distances, you may want a little more toe room to account for swelling. For speedwork, a performance fit is ideal.

Don’t rely on the stated size alone. Be sure to judge actual fit and room in the toe box. Everyone’s foot shape is slightly different. Getting the Charged Assert 9’s fit and sizing dialed in is key unleashing this shoe’s energetic ride.

Style options and colorways available

Part of the fun of choosing new running shoes is getting them in your favorite colors and styles. So what are the options when it comes to rocking the Charged Assert 9?

For men, the Assert 9 launches with over 10 color combinations to choose from. There are versatile basics like black, white, and grey. Bold brights include red, blue, orange, and lime green. And for low-key flair, check out the steel/blue dusk or black/green tint options.

Women have around 15 style choices out of the gate. From emerald, pink, and purple pops of color to subtler heathered grey and peach shades. Some colorways are shared across men’s and women’s, while others are unique to each.

In addition to colors, you’ll find different material mixes. Many options use smooth engineered mesh for the upper, but some feature an eye-catching fishnet-style knit texture. This adds depth and personality to the look.

Other stylish touches include speckled midsoles on select colorways and reflective accents on the heels for visibility. Updated colors and prints will likely release over time as well.

When it comes to logos and branding, the Assert 9 keeps it clean and minimal. Just simple Under Armour callouts on the side and tongue tab. This allows the technology to take center stage.

So whether you want loud, vibrant hues to turn heads or prefer low-profile, versatile neutrals, the Assert 9 offers plenty of stylish choices for every personal taste. The range of colors and material mixes allow you to add some personal flair to this high-performing running shoe.
