Extremely Lightweight Construction for Faster Times

Track spikes have come a long way since the early days of spiked shoes for running. Modern track spikes like the Nike Zoom Superfly Elite 2 utilize advanced materials and design techniques to create an extremely lightweight shoe that can help runners achieve their fastest times.

The key to the Superfly Elite 2’s lightweight design starts right at the sole. Nike constructed the sole from Pebax, an advanced polymer that provides stiffness and response while weighing a fraction of what a traditional plastic or carbon fiber plate would weigh. Pebax allows the Superfly Elite 2 to have a stiff sole for powerful toe-offs but still come in at just 3.5 ounces per shoe in a men’s size 9.

Nike also utilized a micro-thin upper made from an engineered mesh material on the Superfly Elite 2. This material stabilizes the foot over the sole while adding virtually no weight. Strategically placed thermoplastic polyurethane (TPU) filaments provide structure and durability with very little added weight. The result is an upper that feels like a second skin for a barely-there feel.

Additional weight savings come from the track spikes themselves. Nike utilized ultra-lightweight titanium for the forefoot spikes on the Superfly Elite 2. At just 0.06 ounces per spike, these titanium spikes shed precious grams without compromising grip and traction on the track. Nike also re-engineered the mounting process for the spikes to eliminate excess material, further reducing weight.

Weight savings also come from the lack of a midfoot shank. Many track spikes utilize carbon fiber shanks to provide stiffness in the midfoot area. The Pebax sole on the Superfly Elite 2 allows Nike to achieve ample stiffness without an additional shank, saving even more weight.

The Pebax plate also extends into the midfoot, providing a smooth transition from heel to toe. Small cutouts in the forefoot plate help improve flexibility for a natural foot movement through toe-off. Additionally, Nike incorporated a zoom air pod under the forefoot for responsiveness and energy return.

Additional details like an angled heel counter, ample perforations on the upper, and a lightly padded heel collar round out the lightweight design elements. The result is a track spike that tips the scales at just 3.5 ounces, shedding every possible ounce to help runners reach top speeds.

Snug Midfoot Wrap for Security

While removing weight was clearly a priority, Nike still incorporated design elements to make sure the Superfly Elite 2 secures the foot. This is particularly important in an extremely lightweight spike where stability could be compromised.

Strategically placed TPU filaments wrap the midfoot for a snug, supportive fit. These filaments integrate seamlessly into the upper material, providing structure and security with very little added weight or bulk.

Nike also extended the Pebax sole upward on the medial side. This creates a sort of midfoot “brace” that cradles the arch of the foot for a locked down feel. Runners report feeling very secure even during hard cornering and acceleration.

Additionally, the heel counter on the Superfly Elite 2 helps lock down the heel. The counter angles forward as it extends up the midfoot area. This shape cups the calcaneus (heel bone) and prevents any slipping or movement inside the shoe.

Finally, the lightly padded tongue and heel collar add comfort while helping secure the top of the foot. The result is a supremely locked down midfoot for confident cornering and hard acceleration out of the blocks.

Full-Length Carbon Fiber Plate Options

The Nike Zoom Superfly Elite 2 utilizes Pebax in the plate for an optimal balance of stiffness, toughness, and weight savings. However, some runners prefer the maximum stiffness that a full carbon fiber plate provides.

For those runners, Nike offers the Superfly Elite 2 with a full-length carbon fiber plate. This variant has the same ultra-light upper as the standard Pebax model but replaces the Pebax with a carbon fiber plate. The carbon fiber extends from heel to toe for uncompromising stiffness underfoot.

Stiffness ratings for the carbon plate Superfly Elite 2 exceed even the top-end Nike Dragonfly spike. For sprinters and short distance runners who want absolute stiffness for powerful toe-offs on the track, the carbon plated model delivers.

One downside to the carbon fiber plate is increased weight. The carbon version comes in around 0.6 ounces heavier per shoe versus the Pebax model. However, some runners are willing to take the weight penalty in exchange for the greater forefoot stiffness.

For most runners, the standard Pebax Superfly Elite 2 provides more than adequate stiffness at a very light weight. But for those wanting track spikes as stiff as possible, the carbon plate model gives another option.

A Competition Proven Model

In just its first year on the market, the Nike Zoom Superfly Elite 2 has already been worn by athletes competing at the highest levels of track and field. The 2021 Olympic Games showcased the Superfly Elite 2 on the feet of sprinters and hurdlers across the globe.

Not only elite professionals, but also high school, collegiate, and club level runners are reporting fast times and new PRs in the Superfly Elite 2. The combination of ultralight weight and a stiff, responsive plate is helping runners of all levels achieve their potential on the track.

A Versatile Track Spike

While designed primarily for the 100m to 400m sprints, the Nike Zoom Superfly Elite 2 has proven versatile enough for middle distance athletes as well. The zoom air pod provides responsive cushioning on impact, making the Superfly a capable spike for 800m races and even the mile.

The relatively stiff plate also provides the acceleration required in a middle distance race. While middle distance spikes often prioritize forefoot flexibility over stiffness, the Superfly Elite 2 strikes a good balance for 800m runners.

In the 100mh and 110mh hurdle events, the Superfly Elite 2’s stiff plate offers good push off as hurdlers drive out of the blocks and over the first few hurdles. The low 3.5 ounce weight also suits hurdlers who need a light, fast shoe out of the blocks and down the straightaway.

While designed as a sprint spike first and foremost, the Superfly Elite 2 has proven versatile enough for middle distance and hurdlers seeking a responsive, lightweight shoe.

The Nike Zoom Superfly Elite 2 utilizes intelligent design and advanced construction techniques to achieve an incredibly lightweight spike. The stiff Pebax plate, barely-there upper, and titanium spikes enable elite-level performance for sprinters without compromising stability. With competition records and medals already under its belt, the Superfly Elite 2 establishes itself as a top-tier track spike across events.
Here is a 1000+ word article on the Nike Superfly Elite 2 track spikes:

Highly Breathable Woven Upper for Maximum Comfort

Any great track spike needs to balance lightweight performance with comfort. Despite its barely-there 3.5 ounce weight, the Nike Zoom Superfly Elite 2 utilizes an engineered upper material that provides the comfort needed for intense training and all-out racing.

Nike constructed the Superfly Elite 2 upper from an exceptionally lightweight woven material. The tight weave offers strength and structure with very little material. It also makes the upper extremely breathable to keep feet cool and dry on hot track days.

Unlike traditional polyester uppers that can feel hot and restrictive, the woven upper of the Superfly Elite 2 feels smooth and airy against the foot. Even in sweltering conditions, feet stay ventilated for mile after mile on the track.

The micro-thin strands that make up the woven upper also conform to the exact shape of the foot for a custom, contoured fit. There are no seams, overlays, or internal booties getting in the way of the foot-to-spike connection.

Strategically bonded TPU filaments provide structure and support while allowing the upper to remain highly flexible and breathable. The filaments integrate directly into the woven material for seamless support right where the foot needs it.

In high stress areas like the midfoot and forefoot, the filaments lock the foot in place without restricting natural movement. Additional filaments wrap the arch and midfoot for a secure fit.

The upper extends all the way to the spike plate for a true one-piece construction. This “upper-as-outsole” design eliminates layers between the foot and track for uninhibited feel and connection. Extending the upper to the spikes also maximizes breathability across the bottom of the foot.

Targeted Padding Where You Need It

While the Superfly Elite 2 upper provides a barefoot-like feel, Nike incorporated selective padding in key areas. The ultra-thin tongue and heel collar use open cell foam to add comfort right where needed.

The open cell foam compresses easily for a plush step-in feel. However, it regains shape quickly to prevent squishing or instability. This strategic padding allows Nike to add comfort without compromising security.

The heel collar foam in particular wraps the Achilles and molds to the heel for a locked in feel. Excessive padding here might cause slippage, but the open cell foam provides just enough cushioning with no unwanted movement.

Reflective material on the top eye rows adds structure and visibility in low light conditions. Reflectivity here also reduces lace pressure on the top of the foot.

For runners who want a glove-like fit, the padding elements provide the perfect touch of cushioning and comfort over a race-ready spike platform.

Durable Protection in Key Areas

The woven upper of the Nike Superfly Elite 2 provides the ideal blend of breathability and foot-conforming comfort. However, the open weave also exposes the foot to potential wear and abrasion.

To combat this, Nike added durable skin overlays in the highest wear areas. The toe box, medial forefoot, and bottom of the spike plate get thin TPU skin overlays that protect the foot from damage.

These skins have a matte finish to integrate seamlessly with the upper material. Runners will not even notice they are there until inspecting the shoes up close. But the skins provide substantial abrasion resistance in the most vulnerable areas.

The spike cavities are also reinforced with a skin overlay. This protects the spikes from pulling through or damaging the upper material. A pull-through spike failure could end a runner’s race, so this overlay provides critical reinforcement.

While the upper is incredibly lightweight as a whole, these strategic skin overlays provide abrasion resistance right where needed. Runners get durable protection without compromising the airy feel and breathability of the woven upper.

A Personalized Fit

The Nike Superfly Elite 2 utilizes a traditional lacing closure system to secure the foot. While some track spikes are incorporating alternative closure systems like hydropull tabs, the Superfly Elite 2 sticks with a tried and true lacing setup.

Six oval shaped eye rows provide near endless lacing customization options. Runners can lace tight through the midfoot for maximum security, or loosen up for a more relaxed fit. The thin, rounded laces knot up easily and lay smoothly across the top of the foot.

A wide lacing window ensures easy access to the eye rows for quick and easy adjustment. The burrito tongue construction wraps the midfoot smoothly to prevent any pinching from the laces or upper seams.

While simple in design, the lacing system lets runners truly customize the upper fit. Combined with the woven upper material, runners get a personalized track spike that feels like an extension of the foot.

Through intelligent material selection and strategic padding placement, Nike created an incredibly lightweight yet comfortable track spike upper. The Superfly Elite 2 sets the standard for woven, breathable uppers that disappear on the foot over any race distance.

Aggressive Pebax Plate for Strong Propulsion

Generating explosive speed and power requires uncompromising stiffness underfoot. That is why Nike equipped the Superfly Elite 2 with an aggressive Pebax plate that remains rigid through toe-off to propel runners down the track.

The Pebax plate provides a precision balance of stiffness, snap, and vertical stiffness. Pebax allows Nike to tune the exact stiffness characteristics for elite sprinting performance.

In the forefoot, the plate maintains ample flexibility to allow natural foot movement. But when driving off the toes, the plate stiffens dramatically to create a rigid lever for propulsion. This delivers the plate stiffness aggressive sprinters need without compromising comfort.

The Pebax material also rebounds aggressively to return energy into the runner with each step. Unlike carbon fiber plates that deliver stiffness at the expense of snap, the Pebax plate provides an excellent combination of both.

Nike positions the plate directly under the ball of the foot, where stiffness matters most. This strategic placement and Pebax material selection unlocks stronger propulsion than a traditional spike plate.

The plate also extends into the midfoot to provide stiffness and stability during acceleration. A rigid platform here helps sprinters stay on their toes driving out of the blocks.

For all out sprinting, the Superfly Elite 2 plate delivers the right combination of flexibility where needed and game changing stiffness precisely where it matters most.

Zoom Air Unit for Responsiveness

In addition to the aggressive Pebax plate, Nike equipped the Superfly Elite 2 with a Zoom Air unit under the forefoot. This provides responsive cushioning to complement the plate.

Zoom Air units compress on footstrike to dampen impact forces. But the air bag springs back aggressively to return energy into the runner.

This delivers a propulsive sensation runners can feel under the ball of the foot. Together with the Pebax plate, the Zoom Air unit creates fast, responsive toe-offs.

The Zoom Air pod utilizes incredibly thin TPU encapsulating skins to minimize weight. Despite this light construction, the Air unit delivers ample impact protection and energy return.

Positioning the Air unit up front complements the stiffness focus of the plate. For middle distance racers, the forefoot Air unit also maintains comfort lap after lap.

This combination of aggressive propulsion from the plate and cushioned responsiveness from Zoom Air gives the Superfly Elite 2 its unique, fast ride.

Anatomically Contoured Shape

In addition to stiffness and snap, the Superfly Elite 2 plate provides an anatomically contoured shape. This natural shape mirrors the form of the foot for smooth, comfortable transitions.

In the midfoot area, the plate curves to match the medial arch. This supports the natural shape of the foot, reducing stress or strain on arches and joints.

The contoured shape also rolls smoothly from initial contact to toe-off. No flat or excessively stiff areas impede the foot’s natural motion.

In the forefoot, flex grooves align with the foot’s metatarsophalangeal joints. This allows natural articulation and flexion which stiff plates often restrict.

By shaping the plate to the foot, Nike eliminated uncomfortable pressure points and restriction. Runners experience a smooth, natural feel lap after lap.

For fast, fluid transitions, the contoured shape works synergistically with the tuned stiffness. Together, they deliver explosive acceleration and efficiency.

Waffle Spike Plate for Traction

Delivering strong propulsion requires maximizing traction and grip on the track surface. To achieve this, Nike equipped the Superfly Elite 2 with a waffle pattern spike plate.

The waffle design covers the entire forefoot with raised rubber for surface contact and traction. The waffle lugs are beveled to further increase ground penetration and grip.

This full ground contact design puts more rubber on the track for better traction than a traditional spike plate. The waffle patter multiplies surface friction for strong acceleration out of the blocks.

The waffle spikes are also staggered to provide traction in multiple directions. Whether sprinting straight ahead or cornering hard, the Superfly Elite 2 plate sticks to the track.

Spike pressure distributes broadly across the waffle plate, reducing risk of isolated pressure points. After long sprints or races, feet feel fresher compared to traditional spike plates.

Nike paired this durable rubber spike plate with aggressive titanium spikes up front. The resulting combination delivers maximum grip and propulsion for PR performances on the track.

Through an innovative Pebax plate design and integrated Zoom Air unit, the Superfly Elite 2 provides the propulsion and responsiveness elite sprinters demand. This technology allows the Superfly Elite 2 to push limits on the track.

Zoom Air Forefoot Cushioning for Impact Protection

While lightweight and stiffness are priorities in a track spike, sufficient cushioning still plays an important role. The forefoot of the Nike Superfly Elite 2 utilizes Zoom Air cushioning pods to provide responsive comfort over any race distance.

Zoom Air units compress on impact to protect the foot, then spring back forcefully. This delivers a sensation runners can feel as the Air pods return energy into their stride.

In the Superfly Elite 2, a Zoom Air unit sits under the ball of the foot for cushioning precisely where needed. On each footstrike, the Air compresses to soften impact forces before toe off.

This responsive cushioning maintains comfort during repetitive impacts lap after lap. Even in longer middle distance races, feet stay fresh thanks to Zoom Air responsiveness.

The Zoom Air pod utilizes a thin TPU encapsulating skin to contain the pressurized air. This ultra lightweight skin allows excellent compression and energy return from the Air unit. Despite its light construction, Zoom Air provides durable cushioning mile after mile.

During sprint acceleration, the Zoom Air pod also contributes to a propulsive sensation. As the Air springs back from compression, runners feel the return energy pushing them forward.

Zoom Air in the Superfly Elite 2 delivers cushioning where runners need it most, while remaining lightweight enough for the track.

Full-Length Carbon Fiber Plate

Some runners prioritize absolute plate stiffness over cushioning characteristics. For those runners, Nike offers a Superfly Elite 2 model with a full-length carbon fiber plate.

The carbon plate variant has the same upper and Zoom Air unit as the regular Superfly Elite 2. However, the Pebax plate gets replaced with rigid carbon fiber.

Extending from heel to toe, the carbon plate maximizes stiffness and rigidity. There is no Pebax curve under the midfoot, just pure stiffness across the entire spike.

For sprinters who care solely about forefoot stiffness for acceleration, the carbon plate delivers. Stiffness ratings for the carbon Superfly exceed even top-end spikes like the Nike Dragonfly.

The downside is increased weight. The carbon plate adds around 0.6 ounces per shoe versus the Pebax plate model. However, some sprinters gladly take the weight penalty in exchange for greater plate rigidity.

With ample forefoot cushioning from Zoom Air, the carbon plate Superfly Elite 2 caters to runners wanting absolute stiffness without compromising comfort.

Heel Design for Security and Transitions

In the heel area, the Superfly Elite 2 prioritizes security, control, and smooth transitions over cushioning. This aligns with the spike’s sprint-focused design philosophy.

The Pebax plate extends into the heel area before curving upward. This provides rigidity from footstrike through toe-off for confident control.

Under the very rear of the heel, Nike removed material from the Pebax plate to improve flexibility. The hollowed out section allows just enough compliance for a smooth initial footstrike before the plate stiffens.

An external heel counter also wraps the heel for security and control. This molded TPU piece cups the calcaneus (heel bone) to prevent unwanted movement inside the shoe.

Finally, the minimal heel padding focuses on comfort over cushioning. The collar lining provides a plush step-in feel without being overly soft or pillowy.

Together, these heel elements deliver control and stability while allowing just enough compliance for smooth transitions during high speed running.

For sprinters focused on acceleration and toe-off stiffness, the heel design strikes the right balance. Cushioning takes a back seat to security, traction, and propulsion in the Superfly heel.

Through Zoom Air units up front and a tuned heel design, the Superfly Elite 2 nail the cushioning formula for elite sprinting and short distance performance. The spike protects and comforts without compromising the track feel and stiffness sprinters need.

Carbon Fiber Plate for Rigid Support and Energy Return

For sprinters and short distance runners seeking absolute plate stiffness, Nike offers the Superfly Elite 2 with a full length carbon fiber plate. This maximizes rigidity and energy return for elite level performance.

The carbon fiber plate variant has the same ultra-light upper and Zoom Air cushioning as the regular Superfly Elite 2. However, the Pebax plate gets replaced with carbon fiber for greater stiffness.

The carbon plate runs the entire length of the spike for consistent rigidity from toe to heel. There is no flexibility under the midfoot like the Pebax plate. Just pure stiffness across the whole spike.

For sprinters who care solely about forefoot stiffness, the carbon plate delivers. Stiffness ratings exceed even top-end spikes like the Dragonfly and rival super-rigid sprint spikes.

This exceptional stiffness comes from the properties of carbon fiber itself. The carbon’s tightly woven fibers create a stiff, rigid material that flexes very little under load.

Carbon fiber also provides a strong energy return effect. As the plate compresses and rebounds with each stride, it returns energy back into the runner for added propulsion.

The downside to the carbon plate is increased weight. It adds around 0.6 ounces per shoe versus the Pebax model. However, some sprinters gladly take the weight penalty in exchange for greater plate rigidity.

Maximized Stiffness for Acceleration

The key benefit of the carbon plate is maximized stiffness and rigidity for sprinting acceleration and maintaining top speed.

Out of the blocks, sprinters can fully load the stiff carbon plate to propel themselves down the track. The rigid lever provides a strong foundation for applying maximum force into the track.

There is no midfoot give or flex like with the Pebax plate. Just pure stiffness for driving off the toes with each powerful stride.

The consistent stiffness also maintains efficiency at max velocity. Unlike spikes with flexibility up front, the carbon plate stays rigid to continue providing strong toe-offs late into the race.

For short distance sprinters going all out for performance, the carbon plate Superfly Elite 2 delivers the uncompromising rigidity needed to reach max speed.

Tuned Shape for Natural Running

While incredibly stiff, Nike still tuned the shape of the carbon plate for natural running mechanics. An uneven or overly rigid spike plate often leads to discomfort and foot fatigue.

Under the forefoot, Nike sculpted flex grooves aligned with the metatarsophalangeal joints. This allows the toes to move and flex naturally through toe-off.

In the midfoot, the plate mirrors the shape of the medial arch. While not flexing like the Pebax plate, it provides support under the arch to reduce strain.

The contoured shape under the heel is also important. It sits flush on the track then curves smoothly upward behind the foot. This tuning avoids having a flat carbon section striking the ground, which could be harsh.

Careful contouring and shaping ensures the plate remains rigid where needed, yet still allows a smooth heel to toe transition. The carbon Superfly Elite 2 retains a natural feel despite the added stiffness.

Proven Plate Technology

This is not Nike’s first track spike utilizing carbon fiber plate technology. Models like the Zoom Maxfly and Vaporfly featured rigid carbon plates years before the Superfly Elite 2.

However, recent advances in carbon fiber manufacturing allow Nike to maximize stiffness while minimizing weight. The Superfly Elite 2 carbon plate provides Formula 1 levels of rigidity at a sprinting spike weight.

Elite sprinters and runners have already recorded unbelievable performances in carbon plated Nike spikes. From world records on the track to marathon podiums, this technology proves performance.

For sprinters and short distance runners wanting the latest in plate innovation, the carbon fiber Superfly Elite 2 delivers. Nike paired revolutionary plate design with a featherlight upper for maximum acceleration.

The carbon fiber plate Superfly Elite 2 gives sprinters a purpose built tool for chasing speed and new PRs. This pinnacle of stiffness and energy return helps elite athletes reach their potential on race day.

Ultralight Foam Midsole for Soft Landings

The pursuit of faster times inevitably leads to lighter and lighter footwear. Yet a track spike still needs sufficient cushioning for comfort lap after lap. For the Superfly Elite 2, Nike developed an innovative ultralight foam midsole that softens impact while disappearing underfoot.

Traditional EVA foam midsoles provide cushioning, but add unwanted weight. So Nike formulated an entirely new responsive foam material exclusive to the Superfly Elite 2.

This Nike Foam midsole utilizes an expanded nucleated cell structure to deliver exceptional lightness. Tiny foam cells provide a “trampoline” effect for soft landings with less material.

In a men’s size 9 spike, the midsole weighs just 1.5 ounces yet delivers responsive cushioning on impact. Runners describe the feel as soft without any mushiness or instability.

The magic lies in the nucleated foam cells dissipating impact forces and releasing stored energy back into each stride. Despite its minimal weight, Nike Foam offers more than enough comfort for elite racing.

Strategic Foam Placement

Nike concentrated foam cushioning in the heel and midfoot areas that need impact protection most. The forefoot utilizes just enough foam to smooth the underfoot feel.

Heelstrikers benefit from the most foam placed for soft landings. As the heel contacts down, the foam compresses to cushion before stiffening up for a smooth transition.

In the midfoot, foam fills the cavity under the arch for a plush step-in feel. This midsole cushioning works together with the contoured plate for arch support.

Under the metatarsal heads (ball of foot), just enough foam covers the spike plate to prevent a harsh feel. The responsive foam dampens forefoot impacts despite its minimal thickness here.

Thin foam under the toe joints also allows natural flexion for smooth toe-offs. Targeted foam placement provides cushioning without impeding takeoffs.

Stable Platform Underfoot

In addition to impact cushioning, the Superfly Elite 2 midsole provides a stable platform underfoot for confident acceleration.

The smooth foam surface ensures the foot remains centered over the stiff plate. There are no harsh edges or uneven surfaces that can cause instability.

Heel to toe, the midsole fills space between the upper and plate for a consistent underfoot platform. Runners describe a balanced, connected feel critical for achieving top speeds.

Additionally, the midsole extends into the lateral heel and forefoot for structure and support. This cradle helps lock the foot in place over the plate.

Despite its soft feel and minimal weight, the Superfly Elite 2 midsole delivers stability and security on the track. It supports foot movements rather than destabilizing the natural gait cycle.

Nike Foam technology allowed designers to add cushioning and stability without compromising the spike’s elite-level lightweight performance. The midsole disappears underfoot but makes its presence felt through soft landings and smooth transitions.

Minimalist Flyknit Upper for Secure Lockdown

The upper of a track spike plays a critical role in stability and security at high speeds. For the Superfly Elite 2, Nike utilized an engineered Flyknit material to deliver a barely-there feel with total lockdown.

Flyknit uppers utilize a specialized knitting process to create a seamless, sock-like fit. The micro-engineered yarns wrap the foot in targeted support without overlays or stiff layers.

This Flyknit upper comes in at an incredibly light 1.5 ounces in a men’s size 9. It forms to the exact shape of the foot for a customized, second skin feel.

Despite its minimalist design, integrated Flywire cables and strategically bonded filaments provide lockdown where needed. The Superfly Elite 2 upper secures the foot without restrictive hot spots.

Special construction in the arch and midfoot integrate areas of denser knit tension. This dynamic Flyknit actively tightens around the midfoot when laces are cinched.

The result is an upper disappearing on the foot for unimpeded connection to the track. But it still provides the support and security necessary for all out sprinting.

Targeted Reinforcement

While incredibly minimalist overall, Nike strategically reinforced high-stress areas on the Superfly Elite 2 upper.

The toe box receives welded overlays for abrasion resistance and structure. This protects toes from damage during powerful push offs down the track.

In the midfoot, Nike incorporated a dense polymer frame wrapping from under the arch up the medial side. This cups the midfoot for stability while resisting stretch or deformation.

The eyestays and lace loops also utilize stiff composite materials to maintain the snug fit over many sprint sessions. Despite its stretch knit design, the upper does not lose structure or security over time.

Heel support comes from an internal heel counter moulded directly into the knit material. It provides heel lockdown with no added layers or bulk.

These reinforcement elements allow the Flyknit upper to remain breathable and flexible while still providing lockdown sprinters can trust.

Quick Lacing Adjustability

Despite its seamless design, the Superfly Elite 2 still utilizes a traditional lace up closure for adjustable support.

Six asymmetric lace loops thread thin, round laces from toe to ankle. This allows customizing tension across the top of the foot quickly and easily.

The burrito-style tongue construction wraps the midfoot smoothly when tightened down. Perforations right above the tongue keep the area ventilated.

For racers wanting to tweak midfoot or arch security, the lacing system provides easy on-the-fly adjustments. The simple design also eliminates bulky mechanical components or reduced adjustability of other closure systems.

Between the smooth, seamless Flyknit and simple lacing, the Superfly Elite 2 upper secures the foot without pressure points, layers, or excess components. Anatomic design allows the minimalist upper to deliver a perfect fit every time.

Through precision engineering and advanced knit technology, Nike created a track spike upper that disappears on the foot yet excels at keeping it locked in place. The Superfly Elite 2 sets the standard for supportive minimalism.

Aggressive Spikes for Superior Traction

Generating lightning fast acceleration and top speeds requires maximizing grip and traction on the track surface. To achieve this, Nike equipped the Superfly Elite 2 with 6 aggressive titanium spikes in the forefoot.

The lightweight titanium material allowed Nike to engineer an incredibly sharp and durable spike shape. The pyramid design penetrates the track for immediate grip on contact.

Spike pressure distributes across each pyramid tip to provide focused pressure without excessive track abrasion. The spikes remain legal for all track surfaces.

Nike strategically mapped the spikes under the ball of the foot for optimal acceleration traction. Additional spikes under the medial forefoot and big toe deliver grip for tight cornering.

With spike pressure focused right where runners apply propulsive force into the track, the Superfly Elite 2 bites down with authority to minimize slippage.

Heel and Midfoot Traction Pods

While the aggressive spikes dominate traction up front, Nike still equipped the rear and midfoot with grip elements.

The split heel utilizes durable carbon rubber for traction from that initial foot plant. Rubber lugs under the medial and lateral heel secure foot contact before transferring forces forward.

In the midfoot area, the Pebax plate extends outward and incorporates shallow lugs for grip. These work together with the heel traction pods for a controlled foot rollover.

Though the heel has sufficient traction already, Nike offers add-on heel spikes for additional grip. These screw into the pre-threaded heel holes and provide 6 more points of ground contact.

Between the responsive plate and targeted traction elements, the Superfly Elite 2 sticks during each footstrike for confident acceleration down the track.

Waffle Shape Multiplies Grip

The aggressive titanium spikes utilize a waffle shaped base that further enhances traction capabilities.

Rather than simply spike mounts, the waffle base features raised rubber surrounding each spike. This puts more rubber in contact with the track for maximum grip.

The waffle design also channels dirt and debris away from the spike cavity for unimpeded ground penetration lap after lap.

Despite the highly abrasive nature of track sprinting, the spike plate rubber shows minimal wear over time. The waffle shape distributes stresses more evenly across the outsole.

Spikes mounted directly in the Pebax plate deliver responsiveness while sitting in the durable waffle rubber base. Traction, grip, and propulsion come together in one integrated design.

For elite racers wanting every possible advantage out of the blocks, the Superfly Elite 2 delivers traction capabilities unmatched by rivals. The spike plate chews up the track for immediate grip and sustained traction at any speed.

With razor sharp spikes up front and durable rubber in back, Nike obsessively engineered the Superfly Elite 2 for superior footing on race day. Traction plays a pivotal role in unleashing a runner’s true potential.

Aerodynamic Shaping for Less Wind Resistance

At high sprinting speeds, wind resistance can significantly impede performance. To counteract this, Nike designed the Superfly Elite 2 spike with aerodynamic shaping to slip through the air with less drag.

In the forefoot, the low-profile design keeps the spike close to the track for a minimized frontal profile. The curves of the plate smoothly transition to the sleek upper to avoid abrupt edges catching air.

The heel is also clipped low and tapered. An external heel clip streamlines airflow off the heel compared to bulky internal counters.

In the midfoot, Nike bonded flat seams and minimized layering and overlays. This further reduces the side profile exposed to oncoming wind.

Venting in the upper also contributes by allowing air to pass through rather than causing drag. Strategic perforations keep just a single layer of material without compromising structure.

Even the spike plate prioritizes aerodynamics. The waffle shape brings rubber contact close to the track without increasing upward height. Titanium spikes also cut through air more smoothly than bulky alternatives.

Lightweight Construction

In addition to shaping, minimizing overall weight also reduces drag. The Superfly Elite 2’s mere 3.5 ounce weight (men’s size 9) cuts through air easier than heavier models.

Paring the spike down to only essential components allowed Nike to ditch bulky layers that impair aerodynamics. New manufacturing techniques also enabled lighter yet stronger materials.

The Pebax plate provides stiffness and snap at just a fraction of the weight of a plastic nylon plate. The micro-engineered upper also slashed weight without compromising security and structure.

Athletes feel less mass resisting forward momentum in the featherweight Superfly Elite 2. Less weight translates to quicker times on the track.

Wind Tunnel Testing

Nike utilized sophisticated wind tunnel testing during Superfly Elite 2 development to analyze aerodynamic drag

By visualizing air currents and measuring resistance values at race paces, designers refined the shape for maximal wind-cheating performance.

Subtle tweaks like flare at the heel edge, beveling at the toe, and recessed spikes delivered measurable drag reductions compared to earlier prototypes.

Extensive computational fluid dynamics simulation also virtually modeled airflow and drag. This allowed rapid design iteration without costly wind tunnel tests.

The final Superfly Elite 2 shape excels in both real world wind tunnel tests and virtual simulations. Data drove aerodynamic enhancements for PR performances.

Through precision engineering and extensive trial testing, Nike optimized the Superfly Elite 2 to neutralize the performance robbing effects of wind resistance. Streamlined shaping ekes out every possible advantage for today’s elite sprinters.

High Abrasion Rubber Outsole for Durability

The relentless forces and abrasive surfaces encountered during sprinting necessitate spike outsoles with exceptional durability. For the Superfly Elite 2, Nike utilized premium rubber compounds to withstand harsh track environments lap after lap.

The full ground contact waffle spikes feature high abrasion rubber for unbeatable traction and resilience. This rubber compound shows very little wear even when sprinting on rough track surfaces.

In the heel, the split pod construction maximizes rubber surface area for durability. Two separated nodes spread out forces and impacts for reduced wear and tear.

The Pebax plate itself resists abrasion and maintains stiffness long term. Nike also extended the plate through the midfoot for protection from kicking up debris.

Skin reinforcements in the toe box and other high wear zones provide defense against damage. Heat welding bonds the skins flush with the upper for smooth protection.

Reinforced Spike Cavities

The spike cavities themselves require special reinforcement to prevent ripping and blowout from repeated force transmission.

Nike molded the spike holes within TPU skins bonded to the upper material. This reinforcement ring around each cavity keeps the spikes securely anchored.

The waffle shaped base under each spike also protects the upper. It distributes pressures more evenly than a single point of contact, reducing risk of pull throughs.

Anatomical Toe Box for Natural Foot Splay

Generating powerful toe-off requires freedom for the foot to splay naturally at push off. To facilitate this, Nike sculpted the Superfly Elite 2 with an anatomical toe shape allowing unrestricted natural movement.

In sprint spikes, toes often feel restricted and bunched together, limiting leverage and power. The Superfly Elite 2 toe box instead provides a wide, foot-shaped platform.

This extra forefoot volume gives toes room to spread out and drive down against the plate. Runners experience significantly greater traction and control from a full foot splay.

The height of the toe box also follows the natural toe contour. There is no abrupt bump or ridge limiting joint flexion as toes bend at push off.

By removing restrictive barriers, the Superfly Elite 2 toe box unlocks a runner’s full acceleration and speed capability. Free toes translate to faster race times.

Seamless Interior Construction

Inside the toe box, Nike utilized a smooth one-piece interior construction to avoid hot spots or pressure points.

The micro-engineered Flyknit upper extends seamlessly from under the foot up to the toes. No internal layers or overlays create discomfort across the sensitive forefoot.

Even at the highest sprint speeds, feet feel completely locked in yet unrestricted. The foot moves and flexes naturally as one piece with the spike.

Targeted exterior welds provide structure without restricting interior space. Durable skins protect against wear while allowing the foot to expand and contract.

This invisible, foot-mapped interior removes distractions when putting power down. All energy flows cleanly into the track through stable, grounded toes.

Toe-Off Flex Notches

To further promote natural motion, Nike incorporated flex notches at the toe joints. These grooves align with metatarsophalangeal joints.

As the toes bend upward at push-off, these notches allow the sole to flex smoothly. Rigid plates often restrict this motion, leading to discomfort.

By enabling natural flexion, the flex notches eliminate toe jamming and pain. Cushioning foam filling the notches eliminates pressure points.

Together with the spacious toe box, these flex features allow forceful toe-offs lap after lap. The foot moves naturally while maintaining stiffness and power transfer.

Nike engineered the Superfly Elite 2 forefoot for one purpose: unleashing a sprinter’s acceleration and speed potential through unrestricted foot mechanics. The toe box provides freedom while the plate still delivers stiffness below.

Efficient Power Transfer for Faster Acceleration

The key to fast sprint times lies in transferring every ounce of power from foot to track. To achieve this, Nike designed the Superfly Elite 2 to deliver efficient force transmission for lightning quick acceleration.

The Pebax plate provides the foundation, delivering stiffness precisely where needed for powerful toe-offs. Pebax construction balances flexibility and snap to channel power down the track.

In the forefoot, flex grooves align with joints for unrestricted toe articulation and leverage. The toe box shape gives room to splay and drive down forcefully off the blocks.

The featherlight upper eliminates interference between foot and spike. Strategically bonded overlays deliver seamless lockdown without impeding natural motion.

Underfoot, the contoured last mirrors anatomical shapes. The foot remains centered and balanced over the responsive plate through the gait cycle.

Every component of the Superfly Elite 2 focuses on transferring force from foot to track in the most streamlined, frictionless way possible.

Powerful Propulsion

During the propulsive toe-off phase, the Pebax plate provides a rigid lever for force application. As the toes depress the plate, it remains stiff for strong propulsion.

The plate extends deep under the ball of the foot to engage the windlass mechanism. This anatomical feature multiplies force transmission for effective push-offs.

Zoom Air units under the toes add responsive energy return to complement the stiff plate. The smooth foam sole ensures uniform power flows into the responsive plate.

Traction elements grip the track as forces drive back. Titanium spikes under the toes penetrate for control, while rubber heels secure the rearfoot.

Every component combines to deliver powerful yet streamlined propulsion through an ideal foot-to-track contact.

Minimal Energy Loss

The Superfly Elite 2 also minimizes energy loss through friction, instability, and deformation. This maintains forward drive through each brief footstrike.

A seamless interior construction eliminates friction hotspots or pressure points robbing power. The burrito tongue construction banishes tongue slide irritation and distraction.

Underfoot, the contoured profile provides a stable platform for smooth transitions. Strategic rigidity in the plate prevents wasted flex and instability.

Lightweight, robust materials withstand deformation that can sap power. The Pebax plate retains its rigid pop every step.

By eliminating energy loss, the Superfly Elite 2 maintains every ounce of propulsive force through ground contact. None gets wasted enroute to the track.

Through tuned construction and obsessive design, Nike created a sprinting spike that transfers force from foot to track with minimal loss. The Superfly Elite 2 puts power down efficiently step after step.

Track spikes are often highly specialized for either sprint or mid-distance racing. The Nike Superfly Elite 2 breaks this mold with versatility for 100m to 800m races and beyond.

Under the forefoot, the Zoom Air unit provides responsive cushioning for middle distance comfort without compromising stiffness. At just 3.5 ounces, weight stays low for sprints.

The Pebax plate balances flexibility under the midfoot for a smooth transition to toe-off. Yet it still delivers stiff acceleration off the blocks.

Traction extends across the entire outsole for grip during constant contact at high speeds. A secure fit keeps the foot locked in place mile after mile.

With professional runners excelling in the Superfly Elite 2 from short sprints to mid-distance, it is clear Nike created a versatile spike.

Ideal for 200m and 400m Races

The Superfly Elite 2’s balance of features makes it an excellent choice for the 200m and 400m sprint races.

At these distances, quick acceleration out of the blocks is still essential. The rigid, propulsive toe-off translates power on the opening straightaway.

Cushioning then plays a bigger role on the turns and closing stretch. Zoom Air protects feet hitting the track at high speeds lap after lap.

Durability also comes into play holding up for 200m and 400m wear and tear. The Superfly Elite 2 provides a durable spike that maintains pop run after run.

For sprinters seeking a versatile spike from short sprints up through the 400m, the Superfly Elite 2 offers the ideal package.

Potential for 800m and Beyond

With sufficient cushioning from Zoom Air, the Superfly Elite 2 has also found favor among mid-distance runners.

The added forefoot protection balances the responsive plate feel over the duration of an 800m race. Traction remains consistent even as fatigue sets in.

Elite milers also appreciate the lightweight feel that still provides some underfoot comfort. The few ounces difference from a dedicated mid-distance spike are negligible for some.

While not ideal for heavy mileage training, the Superfly Elite 2 gives middle distance runners a responsive, race day option from 800m up to the mile.

From start to finish, Nike optimized the Superfly Elite 2 for competitions across the sprint and mid-distance spectrum. Athletes can push speed, performance, and PRs from 100m through the mile.
