Use - The New Balance SD400 v3, as highlighted by the name, is ideal for short-distance running and sprinting meets. These running matches can range from 50 meters all the way up to 400 meters. 

Spike Type - Set as the standard spike pins for track running competitions, pyramid pins are assigned to the sprint spike. These measure ¼-inch in length, sinking into the track surface for stability and propulsion. 

Spike Plate - Similar to the Adidas Adizero Finesse, the short-range running spike is equipped with a TPU plate. It hosts the removable pins of the shoe for versatile traction. Moreover, it keeps a good balance of both stiffness and flexibility.

 

Intended for superior grip, a TPU plate with an eight-spike placement is furnished to the outsole. It also supplies a highly responsive ride. 

For maximum support and security, an internal shank is placed within the midsole. It also heightens the track spike's torsional rigidity.

To keep the lightness of the running shoe, a synthetic upper is incorporated. Moreover, it wraps snugly around the foot, providing optimal lockdown and comfort.

The New Balance SD400 v3 is designed using the standard width for both men and women. Thus, users can get a pair with their usual size preference. 

The components directly influencing the fit of the SD400 v3 are the synthetic upper, midfoot shank, film overlays, and classic lacing closure. The synthetic upper envelopes the foot tightly while still enabling comfort. Lockdown is furthered by the film overlays welded on the upper and the shoe’s lace-up closure. Lastly, to provide structural reinforcement and support, an internal shank is incorporated.

As mentioned, the outsole of the New Balance SD400 v3 is comprised of a TPU spike plate. The same outsole element is present in other track running spikes such as the Adidas Distancestar. The plate keeps rigidity at an optimal level for propulsion and durability. Although distinguished for being stiff, it also keeps a good balance of softness. This aspect of the plate promotes underfoot cushioning and is integral in shock attenuation.

For the midsole compartment, an internal shank is implemented. It amplifies the torsional rigidity of the track spike. This, in turn, boosts the security and support of the sprint shoe.

The upper of the New Balance SD400 v3 features a synthetic material. It lessens the bulk of the running spike as it employs minimal weight. Moreover, it generously wraps around the natural shape and contours of the foot for ultimate security. It also has ventilation zones for breathability, promoting a healthy foot environment. 

Complementing the lockdown provided by the synthetic upper are the film overlays and the traditional lacing system. The overlays keep the foot in place by pushing it down into the midsole. Meanwhile, the lace-up fastening system provides an accurate, dialed-in fit. It accommodates the varying needs of the athletes in terms of closure.
