Whether you’re a seasoned athlete or an aspiring sprinter, the SD100 spikes offer a compelling package that deserves a closer look.
Featherlight Design: Redefining Speed on the Track
One of the most striking aspects of the New Balance SD100 is its incredibly lightweight construction. Weighing in at a mere 3.5 oz for men’s size 9 and 3.2 oz for women’s size 7, these spikes are among the lightest on the market. This featherlight design is achieved through a carefully engineered single-layer mesh upper that minimizes weight without compromising on structure or support.
How does the lightweight design benefit runners? The reduced weight allows for quicker leg turnover, enabling athletes to maintain their pace for longer periods without succumbing to fatigue. This can be particularly advantageous in middle-distance events where maintaining speed throughout the race is crucial.
REVlite Foam: Responsive Cushioning for Optimal Performance
At the heart of the SD100’s midsole lies New Balance’s proprietary REVlite foam. This innovative cushioning material strikes an ideal balance between responsiveness and weight reduction. REVlite compresses upon impact, providing a comfortable landing, and quickly rebounds to propel the runner forward with each stride.
Is REVlite suitable for all runners? While the cushioning offers excellent responsiveness, it’s important to note that the SD100 is best suited for neutral runners. The low-profile design prioritizes speed over stability, making it less ideal for those requiring additional support.
Pebax Spike Plate: Unleashing Unparalleled Traction
The foundation of any great track spike lies in its ability to provide superior traction, and the SD100 excels in this department with its Pebax spike plate. This high-performance material offers an optimal blend of firmness and flexibility, allowing for natural toe flexion during push-off while maintaining excellent grip on the track surface.
The SD100 features a 6-pin spike configuration arranged in an aggressive triangle pattern. This design enables runners to dig into the track effectively, providing explosive acceleration out of the starting blocks and maintaining grip throughout the race. The removable spikes also allow for easy replacement when they begin to wear down, ensuring consistent performance over time.
Flex Grooves: Enhancing Smooth Transitions
Complementing the Pebax spike plate are strategically placed flex grooves. These grooves work in harmony with the plate to facilitate smooth transitions from heel strike to toe-off. The result is a more natural and efficient running motion, allowing athletes to maintain their speed with less effort.
SD Lockdown Lacing: Securing Your Feet for Peak Performance
One common issue faced by track athletes is foot slippage within the shoe, particularly when navigating tight curves at high speeds. New Balance addresses this concern with their innovative SD Lockdown Lacing system in the SD100.
How does the SD Lockdown Lacing system work? This unique lacing configuration is designed to cradle the forefoot and midfoot securely. By moving the lacing eyestays inward, the laces are brought closer together across the tongue, creating a snug fit around the instep. This prevents unwanted movement inside the shoe without restricting the natural flexion of the foot.
The beauty of this system lies in its ability to provide a locked-down feel in the front of the foot while maintaining full mobility in the heel and ankle areas. This balance between security and freedom of movement is crucial for athletes looking to maximize their performance on the track.
Breathable Upper: Keeping Cool Under Pressure
When it comes to intense track events, overheating can be a significant concern. The SD100 tackles this issue head-on with its highly breathable mesh upper. The single-layer construction allows for maximum airflow across the entire foot, helping to regulate temperature and prevent excessive sweating.
What are the benefits of the breathable upper? Runners can expect their feet to stay cooler and drier throughout their races or training sessions. This enhanced ventilation not only improves comfort but can also contribute to better overall performance by reducing the risk of blisters and other heat-related foot issues.
Additionally, the mesh upper is treated with an antimicrobial finish, which helps to resist odor buildup after intense workouts. This feature is particularly valuable for athletes who frequently engage in high-intensity training sessions or compete in multiple events.
Quick-Drying Properties
The lightweight mesh used in the SD100’s upper not only enhances breathability but also boasts quick-drying properties. This can be especially beneficial for runners competing in wet conditions or those who tend to have sweaty feet. The ability to dry quickly helps maintain the shoe’s lightweight feel and prevents the accumulation of moisture that could lead to discomfort or reduced performance.
TPU Guidance Line: Enhancing Stability and Efficiency
Track events often require sudden changes in speed and direction, placing significant demands on a runner’s footwear. The SD100 incorporates a TPU Guidance Line to address these challenges and promote smooth, efficient movement throughout the gait cycle.
What is the TPU Guidance Line? This feature consists of a denser TPU material that extends from the heel through the arch and into the forefoot. Its primary function is to provide structure and guide the foot through each phase of the running motion, from initial contact to toe-off.
By incorporating this guidance system, New Balance has created a spike that offers enhanced stability without adding unnecessary weight. The result is a more controlled and efficient running experience, allowing athletes to maintain their form and speed even during the most demanding parts of a race.
Improved Energy Transfer
The TPU Guidance Line not only enhances stability but also contributes to improved energy transfer. By guiding the foot through a more efficient path, it helps to minimize energy loss during each stride. This can translate to better overall performance, particularly in longer events where maintaining efficiency is crucial.

An Introduction to the New Balance SD100 Spikes
As a runner, I’m always looking for ways to shave precious seconds off my times. Those fractional gains can be the difference between a podium finish and an ‘also ran’ result. That’s why I was immediately intrigued when New Balance released their SD100 track spikes earlier this year. With a lightweight build and performance-focused design, these shoes seem purpose-built for middle distance racers like myself.
In this article, I’ll provide an in-depth look at the New Balance SD100 spikes. From the lightweight Pebax plate to the breathable upper, I’ll cover all the key features and technologies. I’ll also compare them to similar track spikes from Nike and Adidas. Consider this your complete guide to the SD100 and whether they deserve a spot in your racing rotation!
Featherlight Construction for Faster Leg Turnover
The first thing you’ll notice when you pick up the SD100 is how incredibly light they are. The men’s size 9 weighs in at just 3.5 oz, while the women’s size 7 is an equally feathery 3.2 oz. By minimizing weight, New Balance helps you maintain quick leg turnover around the track without tiring as quickly.
This lightweight feel comes from the minimal, single-layer mesh upper. New Balance uses an open construction with very little overlay, keeping the shoes breathable and barely-there on your feet. The ultra-thin fabric also flexes with your foot’s natural movement.
In the midsole, you’ll find New Balance’s REVlite foam. It delivers responsive cushioning in a low-profile design. REVlite compresss on impact for comfort, yet springs back quickly to propel you forward. This lightweight cushioning doesn’t add stability, however – so the SD100 is best for neutral runners.
Aggressive Pebax Spike Plate for Gripping the Track
The key to fast acceleration is traction, and that’s where the Pebax spike plate comes in. Pebax delivers an ideal balance of firmness and flexibility, so the toes can flex naturally as you push off. The forefoot spike pattern also provides plenty of grip on the track surface.
New Balance uses a 6-pin Pebax spike plate. The pins are arranged in an aggressive triangle shape for digging into the track. This gives you solid traction when sprinting out of the blocks or driving hard to the finish line. The spikes are removable, so you can replace them once they start feeling dull.
By combining the Pebax plate with REVlite cushioning, the SD100 delivers that snappy, responsive feel you want when racing. The spikes also transition smoothly due to the smart placement of flex grooves.
Strategic Lacing System Secures Your Forefoot
One pet peeve I have with many track spikes is when my feet slide around, especially during a hard curve on the track. Thankfully, New Balance added their innovative SD Lockdown Lacing to the SD100.
It’s designed to cradle your forefoot and midfoot securely, keeping your feet stable when changing direction at high speeds. The lacing eyestays are moved inward, bringing the laces closer together across the tongue. This snug fit around the instep prevents sliding inside the shoe.
By locking down only the front of the foot, the heel and ankle retain full mobility. The SD Lockdown Lacing hits the sweet spot between security and freedom of movement.
Breathable Upper Keeps Your Feet Cool
During an intense race, your feet can overheat in poorly ventilated shoes. The SD100 has an airy mesh upper to prevent this problem. The single layer construction enhances breathability across the entire foot.
I’ve found my feet stay much cooler in these shoes compared to other track spikes. The lightweight mesh dries quickly if you race in wet conditions. It’s also treated with an antimicrobial finish to resist odor after sweaty workouts.
Inside the shoes, you’ll find a smooth fabric lining rather than a separate sockliner. This helps reduce moisture build-up inside the shoes.
REVlite Cushioning for a Responsive Ride
The SD100 features New Balance’s REVlite midsole, providing low-profile, responsive cushioning. REVlite delivers a firm, snappy feel perfect for fast training and racing on the track.
Don’t expect soft, pillowy cushioning here. Instead, REVlite compresses easily to smooth the landing, then springs back quickly as you transition to toe-off. The result is a fast, efficient ride.
Weighing 30% less than standard EVA foam, REVlite midsoles provide impact protection without the added weight. The reduced weight also contributes to the light, barely-there feel of the SD100.
TPU Guidance Line Enables Smooth Transitions
Track races demand sudden changes in speed and direction. The SD100’s TPU Guidance Line facilitates smooth transitions throughout your gait cycle.
This denser TPU material extends from the heel through the arch to the forefoot. It provides structure to guide your foot through the transition from initial contact to toe-off. The Guidance Line encourages a more natural foot strike.
By stabilizing your foot over the platform, it also reduces torque that can strain your feet and ankles. This helps prevent injury when training and racing in spikes.
Ideal Spikes for Middle Distance Runners
With their lightweight build and snug fit, the SD100 performs best for middle distance track events in my experience. I’d recommend them for races between 800m and 3,000m.
The low 3.5 oz weight suits the faster paces of 800m to 1500m races, where quick foot turnover is essential. The REVlite cushioning provides enough protection for longer 1600m to 3,000m events too.
The SD Lockdown Lacing excels when speeding around the curves in an 800m or 1600m race. It prevents your feet from sliding around inside the shoe.
For sprinting, I’d want the higher stiffness of a dedicated sprint spike. And for 5,000m+ races, I’d opt for slightly more cushioning comfort.
Technical Specs of the New Balance SD100 Spikes
Here are some key technical specs for the New Balance SD100 track spikes:
- Pebax spike plate with 6 removable pins
- Forefoot height of 9.5mm and heel height of 7mm
- Single layer, open mesh upper for breathability
- REVlite midsole provides lightweight cushioning
- SD Lockdown Lacing cradles the midfoot
- Men’s version weighs 3.5 oz and women’s weighs 3.2 oz
How the SD100 Compares to Track Spikes from Nike and Adidas
The SD100 competes directly with Nike’s Zoom 400 and Adidas’ Adizero Prime SP track spikes. Here’s how they compare:
The Zoom 400 has a slightly stiffer Pebax plate and a more rigid midfoot shank for sprinting power. The SD100 and Adizero are more flexible for mid-distance versatility.
Both the SD100 and Adizero use lightweight mesh uppers with minimal overlays, while the Zoom 400 has more structured synthetics. Overall, New Balance’s upper breathes the best.
Underfoot, the Zoom 400 and Adizero offer full-length EVA foam. The SD100 positions firmer REVlite foam only in the forefoot where needed. This optimizes lightweight cushioning.
At 3.5 oz, the SD100 weigh slightly less than the Zoom 400 and Adizero Prime SP. This lightness suits middle distance races better in my opinion.
How to Get the Perfect Fit with the SD100 Spikes
The SD100 runs true to size according to most runners. However, I recommend sizing up by 0.5 if you have wider feet. The Pebax plate doesn’t have much give, so go up half a size for a little extra room through the midfoot.
I also suggest wearing the included New Balance socks or similarly thin racing socks. Thick, cushioned socks can make the shoes feel too snug.
Finally, be sure to lace up the shoes properly by utilizing the SD Lockdown Lacing. Only loosening the first few lower eyelets really locks down your midfoot securely. This prevents sliding that can lead to blisters.
Expert Testers Validate the SD100’s Race-Ready Performance
When reviewing the SD100, wear testers and experts consistently praised their lightweight build and locked-in fit for racing:
“The SD100 spikes felt like an extension of my foot when sprinting and pounding the curves.” – Amanda F., 400m runner
“These are the lightest spikes I’ve ever worn. I can really feel the quick acceleration when driving out of the blocks.” – Ryan J., sprinter
“The grip is excellent even on the dusty track surface. I didn’t slip at all when running hard or leaning into turns.” – Sophie K., 800m runner
Clearly the SD100 deliver on their promise of performance-focused, race-ready speed. The spike plate provides excellent traction and the locked-down fit keeps feet secure when changing speed and direction.

Here are my top tips for optimizing your performance in the New Balance SD100 spikes:
- Use them for practice to break them in properly before racing
- Experiment with sprinter drills to experience the fast toe-off speed
- Wear them for speedwork sessions to adapt to the low-profile cushioning
- Practice leaning into curves to utilize the grippy spike plate
- Swap factory spikes for longer or shorter pins if needed
- Loosen laces across the toes for sprints, tighten for distance
Taking the time to properly break-in the SD100 and tailor them to your foot can maximize the performance benefits.
Caring for Your SD100 Spikes
Here are some tips for extending the life of your New Balance SD100 track spikes:
- Use them only for races and speedwork to limit wear
- Rinse dirt off the spike plate and let air dry after workouts
- Tighten any loose spikes to prevent damage
- Replace dull spikes for optimal traction

Lightweight Construction for Faster Times
When you’re running all-out around the track, every ounce matters. Additional weight on your feet can slow you down in the literal sense. It also increases fatigue so your legs feel heavier late in a race. That’s why the featherlight SD100 construction is so crucial.
At just 3.5 oz for a men’s size 9, these spikes are about an ounce lighter than your typical training shoe. For sprinters and mid-distance runners, less weight translates directly into faster leg turnover and quicker times.
I first noticed the ultra-light feel right out of the box. It’s like holding a performance racing flat, except even lighter. Slipping them on, it’s almost like wearing socks with spikes attached!
On the track, the weight reduction is immediately noticeable. My first session in the SD100 was a set of 200m intervals. Accelerating out of the curve, my feet felt so light and fast. Each stride took less effort than in heavier spikes I’ve worn in the past.
By the later intervals, when fatigue normally sets in, my turnover remained quick and my legs still fresh. The lack of weight kept my feet moving smoothly even as my energy stores depleted. I ultimately ran my last rep a full second faster – proof of the SD100’s speed advantage.
Minimal Upper Design Shaves Off Grams
So how does New Balance achieve such a featherweight build? It starts with the minimalist mesh upper. This single layerconstruction uses an extremely open mesh pattern. The large holes enhance breathability but also reduce weight.
There is no internal bootie or even a full sockliner. A simple smooth fabric lines the interior to cut even more grams. The laces are also lightweight and contain minimal hardware.
By paring the upper down to the essentials, every component contributes to the barely-there feel. Even small details like opting for stitched overlays rather than glued-on synthetics reduces weight ounce by ounce.
REVlite Foam Cuts Heft from the Midsole
The midsole is the other key area where New Balance dropped weight on the SD100 model. Instead of a full-length EVA foam midsole, engineers positioned the lightweight REVlite foam only in the forefoot.
RESP-EVA is a patented foam compound that’s 30% lighter than standard performance foams. So REVlite packs responsive cushioning into just a few ounces underfoot.
The foam doesn’t extend all the way back in the SD100, eliminating any unnecessary heft in the heel and midfoot. This zone-padding approach positions cushioning precisely where needed during your gait cycle.
Spike Plate and Hardware Are Minimized Too
New Balance really sweated the small stuff to optimize the SD100’s weight. Take the removable spike pins for example. They use a streamlined threaded design that’s more skeletonized than old-school cross-country spikes.
The Pebax plate itself has perforations along the edges to carve away superfluous material. The SD Lockdown Lacing relies more on the strategic eyelet placement than thick strapping or overlays.
No detail went overlooked. The result is a spike that strips away every possible gram without sacrificing performance and durability.
Weight Makes a Measurable Difference in My Performance
I’m now a full convert to the performance benefits of lighter spike weight after logging miles in the SD100 model. My time dropped noticeably across distances from 200m repeats up to 1200m time trials.
The faster turnover helps most out of the blocks and around curves. But even on the straightaways, the reduced fatigue helps me hold form and maintain speed right to the line.
My feet and legs simply don’t tire as quickly despite equal effort and intensity. The energy goes directly into driving me down the track rather than lugging extra shoe weight.
While I love the comfort of training shoes for easy miles, nothing can replicate the race-day advantage of an ultralight shoe like the New Balance SD100.
Key Takeaway: Less Weight Equals Faster Times
The bottom line is that lightweight construction makes a measurable performance difference on race day. Even small weight reductions add up to big time drops over repeat laps around the track.
Of course, durability and traction matter too. But all else being equal, I’m now committed to seeking out the lightest spikes possible for competition. The SD100 has me sold on the speed benefits of barely-there footwear!
Aggressive Pebax Spike Plate for Superior Traction
Generating explosive power is crucial in sprints and mid-distance track events. But all that force goes to waste if your shoes can’t grip the surface. That potent combination of propulsion and traction is exactly what the SD100’s spike plate delivers.
New Balance equipped the SD100 with a Pebax plate in the forefoot. Pebax provides an ideal balance of stiffness for force generation and flexibility for smooth transitions. The aggressive spike configuration bites into the track for grip.
After logging some fast interval sessions in the SD100, I’m thoroughly impressed by how this plate performs. My feet feel glued to the track on sharp curves and drive phases. The result is better times from start to finish.
Pebax Plate Offers Stiffness Where Needed
Let’s dig into the details on this proprietary Pebax spike plate. Pebax is a highly-engineered material that New Balance utilizes in many top-tier models. It maintains rigidity for power transfer while allowing a small amount of give for natural foot flexion.
In the SD100 plate, the Pebax is stiffest right under the toes for sprinting power. This rigidity ensures all your leg drive transfers into the track, rather than flexing in the plate. The snappy toe-off really maximizes speed with each stride.
Under the midfoot, flex grooves in the Pebax allow for some flexion as you roll through footstrike. A small degree of midfoot bending helps smooth out transitions for a fluid heel-to-toe gait.
Strategic Spike Design Grips During Acceleration
The next key element is the spike configuration itself. The SD100 uses 6 pins arranged in an aggressive triangle pattern under the forefoot. This layout really digs into the track surface under the ball of your foot.
Having multiple spikes under the metatarsals is crucial for traction during acceleration. All the force is directed foreword as you drive off the starting block and up to top speed.
The Pebax plate also extends forward to position two spikes at the tip of the shoe. This further enhances grip as you push energetically through toe-off.
Testing the SD100’s Cornering and Acceleration Grip
To really test the spike plate’s traction, I performed starts, hill accelerations, and paced intervals focusing on the curve portions.
Accelerating full out from the blocks, my feet felt locked into the track surface. There was no slipping whatsoever despite all my weight and power channeled forward.
Repeating standing hill starts, I again felt only positive traction propelling me up the slope. The Tebax plate provided a rigid platform for force transfer without flex or slip.
Hitting the curves in my interval session, the grip gave me the confidence to lean hard into the turns. The SD100 seemed to hold even more firmly the more force I applied into the track.
Superb Traction Translates to Faster Race Times
By providing such tenacious grip in key phases of footstrike, the SD100 really deliver on race day performance.
I can accelerate harder out of the blocks knowing my feet won’t slip. I can drive harder coming off the curve into the straightaway. And I can change pace entering a kick with total confidence.
The Pebax plate and tuned spike configuration take advantage of the laws of physics. Applying more force vertical into the track actually increases traction horizontally. The SD100 has the chassis to take advantage of that force vectoring.
If you want to convert power into faster race times, the SD100 with its tuned Pebax plate has the traction solution dialed.
Key Takeaway: Grip Equals Speed in Racing Spikes
This experienced really crystallized for me the importance of spike plate traction. Generating power is only half the battle – you need shoes that can effectively transfer force into the track.
New Balance nailed it with the SD100 model. The Pebax material provides the right balance of snappy propulsion and midfoot flexibility. And the aggressive spike placement grips the surface right where needed in key stages of footstrike.
So don’t neglect the spike plate when choosing your next racing spikes! Traction will let you cash in your hard training and power into track PRs on race day.
Strategic Forefoot Lacing for Secure Fit
A locked-in fit is crucial when racing in spikes. Your feet can’t be sliding around inside the shoe when running all-out on the track. That’s why New Balance engineered the innovative SD Lockdown Lacing for the SD100.
This strategic lacing system cradles your forefoot and midfoot snugly. The updated eye-stay placement draws the laces together, acting like a seatbelt across your instep. The result is a fit that secures your foot over the plate without restricting ankle mobility.
After lacing into the SD100 for some threshold repeats, I’m sold on this clever lacing design. My feet felt comfortably supported without any hot spots or pressure points.
Instep Lacing Prevents Sliding Inside the Shoe
The core goal of the SD Lockdown Lacing is preventing in-shoe sliding and slippage. This is accomplished by moving the upper eye-stays inward and angling them toward the tongue.
This draws the laces closer together across the center of the shoe. As you tighten the laces, it tensions the band diagonally over your instep. This snug fit around the midfoot securely locks your foot in place.
You really feel the system engage when entering curves on the track. Centripetal forces want to slide your foot forward, but the lacing keeps you locked above the plate. It was a revelation coming around the first bend at speed!
Free Ankle Articulation for Natural Running Mechanics
Locking down the midfoot doesn’t mean the SD100 restrict mobility, however. The lacing is specifically configured to only secure the instep region.
There are no restrictive overlays across the heel counter or collar lining. The eye stays end mid-foot, so only the first few lower holes pull tight.
My ankles felt totally free and unimpeded at all phases of my gait cycle. On the track, I could swing through my natural running form without constraint from the shoes.
Precise, Uniform Lacing Pressure Across the Instep
Another key benefit of the SD Lockdown system is distributing pressure evenly across the top of your foot. Traditional lacing often cinches too tightly over the joints of your metatarsals.
The SD100’s wide lacing band feels more like a seamless strap distributing forces across your whole instep. There are no pinch points or localized pressure.
Thanks to the angled eye stays guiding the laces inward, tension is directed medially to keep your foot properly aligned above the plate.
A Truly Locked-In Fit Improves Confidence and Safety
After experiencing the SD Lockdown Lacing first-hand, I’ll have a hard time going back to ordinary lacing. The security and confidence it inspires at racing speeds is a real benefit.
I don’t have to consciously think about foot control coming around the bend. I can just focus forward and trust my foot is locked in.
The snug midfoot fit also discourages your toes from jamming into the front of the spikes during fast turnover. This extra toe room is safer over 10000m races.
New Balance’s designers deserve serious credit here. Their novel lacing approach completely eliminates foot slippage while allowing full ankle mobility.
Key Takeaway: Clever Lacing Can Enhance Performance
This experience has changed my thinking about the role of lacing in spikes. It’s not merely about tightening the upper, but strategically locking the foot in place.
Kudos to New Balance for completely rethinking eye-stay placement and lacing vectors. Their solution shows real innovation compared to traditional lacing approaches.
So don’t neglect the lacing design when selecting your next track spikes. The SD Lockdown Lacing provides a real competitive edge by securing your foot over the plate.
Breathable Mesh Upper Keeps Feet Cool
When racing all-out on the track, your feet build up heat quickly. Overheating can ruin your performance as discomfort sets in. That’s why the SD100 upper focuses on keeping your feet cool and dry.
New Balance constructed the upper from a single layer of lightweight mesh. The open holes enhance airflow across your whole foot for ventilation. Despite the thin material, it still provides a secure foothold.
After wearing the SD100 for speedwork on a hot day, I was impressed by how cool and dry my feet stayed. The airy mesh really works to reduce in-shoe temperatures.
Open Mesh Design Maximizes Ventilation
The SD100 skips internal booties and extensive overlays to maximize breathability. The single-layer mesh upper features large, visible openings for airflow.
Air channels through the perforations and directly contacts your foot. This open window design provides constant ventilation from all sides.
Despite the large holes, New Balance still reinforced it in high-stress areas. Fused thermoplastic bits provide structure around the eyestays for security.
Moisture Wicks Quickly from the Foot Chamber
In addition to enabling airflow, the open mesh also effectively wicks moisture from inside the shoes. The thin synthetic fibers don’t absorb and hold sweat like leather or suede.
As my feet perspired during an intense track session, I could feel the sweat evaporating through the mesh. The lining remained dry against my socks.
The quick-drying upper also excels in wet conditions. Driving rain during a rainy tempo run beaded right off the SD100 mesh.
Anti-Microbial Treatment Reduces Odor Buildup
To combat bacteria and foot odor, New Balance treated the mesh upper with an anti-microbial finish. This helps inhibit the growth of odor-causing microbes inside the shoes.
Despite sweating heavily in the SD100 during humid summer runs, I noticed very minimal retained odor or stink. The shoes aired out quickly after use.
The antimicrobial treatment really maintains the freshness despite heat, moisture, and bacteria. My socks don’t take on that stale post-run smell either.
Well-Ventilated Shoes Help Maintain Peak Performance
Racing with hot, uncomfortable feet can ruin your performance and mindset. Just a few degrees of overheating are the difference between a PR and a disappointment.
That’s why cooling features like the SD100’s open mesh upper are so important. Reducing in-shoe temperatures directly correlates to better times on race day.
The SD100 delivers on breathability and moisture management. My feet stayed dry lap after lap during an interval session in muggy conditions.
Don’t resign yourself to swampy shoes and blistery feet. Seek out well-ventilated models like the New Balance SD100 for cooler, drier running.
Key Takeaway: Breathability Matters for Peak Performance
This experience drove home how crucial upper ventilation is for race-day performance. Even minor heat stress can ruin a PR attempt.
New Balance nailed it by pairing an open mesh build with anti-microbial treatments. My feet stayed cool and comfortable despite sweaty summer running.
As temperatures rise, prioritize breathable shoes to avoid stifling your performance. Well-ventilated models like the SD100 ensure you race your best!
REVlite Midsole for Responsive Cushioning
The midsole is a key factor influencing the ride of any running shoe. For the SD100, New Balance chose its REVlite foam to deliver low-profile, responsive cushioning.
REVlite foam provides a firm, snappy feel perfect for fast foot turnover on the track. The proprietary material compresses easily yet rebounds quickly to propel you forward.
After racing 800s in the SD100, I really appreciated the smooth, efficient ride of the REVlite midsole. My feet felt protected yet fast underfoot.
Low-Profile Design Minimizes Heel-Toe Offset
The SD100 features a low-to-the-ground midsole profile, as you’d expect for a racing spike. At the heel, the height is only 7 mm, while the forefoot height is 9.5 mm.
This creates a snug foot-to-ground feel while still providing important impact protection. The low drop between the heel and toe also encourages a natural running gait.
Due to the minimal midsole and lack of insole, my feet rested very close to the Pebax plate. This really maximized road feel feedback for rhythm and pacing.
REVlite foam Compresses and Rebounds Quickly
New Balance formulated REVlite to offer responsive cushioning in a lightweight package. At just 30% the weight of standard performance foams, it packs springy resilience into just a few millimeters.
I noticed the quick compression and rebound during mile repeats on the track. The REVlite foam softened footstrike impacts before springing back for smooth transitions.
This responsive snap underfoot really propelled me along. The firm yet lively feel promoted fast turnover through the gait cycle.
Forefoot-Focused Design Puts Cushioning Where Needed
Since the SD100 is made for speed, New Balance positioned the REVlite foam only in the forefoot. This zone-padding places cushioning and energy return precisely where needed.
The distributed decoupling also helps smooth the toe-off phase of each stride. My feet rolled forward naturally without any harsh slapping.
Trimming the midsole in the heel and midfoot also reduced weight. The SD100 provide protection just where needed while optimizing lightweight performance.
The Takeaway: Light, Lively Foam Enhances Speed
This experience showed me the performance benefits of a well-tuned midsole like the SD100’s REVlite foam.
Its firm yet responsive cushioning delivered a smooth, efficient ride lap after lap. My feet felt protected yet fast thanks to the lively foam.
Seeking out shoes with compressive yet snappy midsoles is key for fast turnover on race day. Models like the SD100 really maximize speed thanks to the dialed foam.
Stable TPU Guidance Line for Smoother Transitions
As a mid-distance runner, I’m constantly shifting speeds – accelerating, decelerating, changing direction. The SD100’s TPU Guidance Line helps me transition smoothly throughout my gait cycle.
This denser TPU material runs down the midline of the outsole, from heel to toe. It gently guides my foot through each step for a more natural footstrike and push-off.
After a track session in the SD100 focused on strides, I appreciated how seamlessly the shoes moved underfoot. The Guidance Line really enhanced the connection between my foot and the spike plate.
Guidance Line Extends Under Arch for Medial Support
The key benefit of the Guidance Line is providing arch support right where needed. The TPU strip runs along the inner midline of the shoes under the arches.
This raised ridge offers a landing platform for my arch to roll over during footstrike. My feet maintained structural alignment lap after lap.
The arch support also discouraged overpronation, keeping my feet straight as I accelerated out of curves. This medial support really enhanced stability.
Heel to Toe Design Enhances Transitions
I also appreciated how the Guidance Line extended forward right through toe-off. This continuity smoothed every phase of my gait.
Landing on the strip at initial contact helped guide my foot rear to forefoot. The extended TPU promoted an aligned rollover through push-off.
Compared to spikes lacking this guidance element, my transitions between steps felt much more connected. The shoes really moved naturally with my biomechanics.
Reduces Torque and Strain on Feet and Ankles
The TPU Guidance Line also has a protective benefit. By stabilizing my foot throughout each stride, it reduces torque through my ankles and arches.
I noticed less strain and twisting compared to other rigid racing spikes I’ve worn in the past. The smoother heel to toe motion results in less fatigue.
This advantage really became clear on longer interval sessions. Maintaining form is easier over more miles thanks to the Guidance Line’s stabilizing structure.
Key Takeaway: Guidance Enhances Natural Running Mechanics
The SD100’s Guidance Line delivered noticeable performance benefits during my testing. My feet moved seamlessly through each stride thanks to the arch and transition support.
Seeking out spikes and shoes with guidance elements is great for smoother runs and injury prevention. The alignment and transition enhancement promotes healthier biomechanics.
Kudos to New Balance for building seamless heel to toe guidance into the SD100 plate. This thoughtful design detail makes a real difference over long workouts.
Ideal for Middle Distance Races and Sprints
With their lightweight build and snug fit, the SD100 spikes perform best for middle distance track events in my experience. I’d recommend them for races between 200m and 1500m.
The featherlight 3.5 oz weight makes the SD100 a great option for sprints from 200m to 400m, where quick turnover is essential. The overall flex of the Pebax plate also suits starting power.
Moving up in distance, the SD100 is equally adept at 800m to 1500m races. The REVlite cushioning provides enough protection for repeats at faster paces up to a mile.
The SD Lockdown Lacing also excels when speeding through the curves in an 800m or 1600m race. It prevents your feet from sliding around on bend entries and exits.
Slightly More Flexible than Pure Sprint Spikes
For pure sprinting, I’d want the greater stiffness and spike pressure of a dedicated sprint spike. Models with carbon fiber plates and/or midfoot shanks better maximize block starts.
The SD100 has some flex through the forefoot that sprinters may find slightly lacking. But for 400m and occasional sprinting, the Pebax plate has sufficient pop.
More Cushioning Comfort Than 5k/10k Racers
At the other end of mid-distances, I’d opt for slightly more cushioning comfort for 5k and 10k races. The SD100 lacks a full-length midsole or removable insole to soften footstrikes.
Minimalist shoes can work for longer distances, but most runners will want a touch more underfoot comforting on 5k/10k race days.
Ideal Weight for Repeated Accelerations
Where the SD100 really shines for me is 800m to 1500m events, where frequent speed changes are essential. The 3.5 oz weight makes them perfect for the repeated accelerations of a 1500m race.
I can count on the quick turnover speed for closing kicks. But the REVlite cushioning also protects my feet grinding through the lactate burn later in the race.
Key Takeaway: Know Your Needs at Different Race Distances
This experience shows the importance of matching your spikes to race distances and priorities. Pure sprinters need maximum stiffness, while longer racers often want more cushioning.
For mid-distance events, the SD100 offer the ideal blend of flexibility, lightness, grip, and foot retention. Their versatile design suits everything from a quick 800m up to a mile.
Think carefully about your needs at specific distances as you choose your next pair of track spikes.

How the SD100 Compares to Other Track Spikes
The SD100 competes directly with track spikes from other top athletic brands like Nike and Adidas. Here’s how the New Balance model stacks up:
Versus Nike Zoom 400
The Zoom 400 has a slightly stiffer Pebax plate and rigid midfoot shank for pure sprinting power. The SD100 is more flexible through the forefoot for middle distance versatility.
Both use Pebax spike plates, but the Zoom 400’s 8-pin configuration focuses traction at the big toe for driving power. The SD100’s triangular pattern grips throughout the forefoot.
The Zoom 400’s upper uses more structured synthetics, while the SD100 has an open, breathable mesh construction. This maximizes ventilation for distance comfort.
Versus Adidas Adizero Prime SP
Adidas incorporates Lightstrike foam in the Adizero Prime SP rather than just in the forefoot like the SD100’s REVlite. This adds underfoot comfort across longer distances.
Both models provide a single layer mesh upper for breathability. However, the SD100 also adds Anti-Microbial treatment for odor resistance as feet heat and sweat.
While the Adizero opts for a traditional lacing system, the SD100’s innovative SD Lockdown Lacing better secures the midfoot for stability in corners.
Key Advantages of the New Balance SD100
Compared to these two models, the SD100 spikes have several key advantages:
- Lighter weight than the Zoom 400 or Adizero Prime SP

Sizing Information for the Perfect Fit
Finding your ideal size is key to getting the best performance from the SD100 spikes. Here are my tips for dialing in the fit:
Go Up Half a Size if You Have Wide Feet
The Pebax plate doesn’t have much give, so I’d recommend sizing up half a size if you have wider feet. The extra room through the midfoot prevents the sides from bulging over the spike plate.
Wear Thin, Low-Profile Socks
The SD100 fit best with lightweight, racing-specific socks. The included New Balance socks work well. Thick, cushy socks take up too much volume inside the shoes.
Make Use of the Complete Lacing System
Fully utilize the SD Lockdown Lacing system by loosening only the first few lower eyelets. Cinch the midfoot evenly by tightening the laces further up the shoe to really lock your foot in place.
Consider Your Foot Volume at Speed
Remember that your feet swell slightly when running fast. So consider sizing up if you are between sizes to leave a little extra room for expansion at race paces.
Try Both Width Options to Get Proper Fit
The SD100 come in D standard width for men and B standard width for women. But New Balance also offers 2E wide for men and D wide for women to accommodate broader feet.
Shop with an Expert at a Specialty Running Store
Visiting a specialty running store ensures you find the right size with input from experts. Many also have treadmills so you can test fit at running speeds.
With athletes relying on such a precise fit for the SD100 to perform, getting the sizing right is crucial.
