The New Balance FuelCell SD-X are lightweight spikes for both men and women. The spikes are specially designed for distances of 200 - 400 meters. Do you want to go for a new PR at this distance? Then the FuelCell SD-X with its streamlined look and snug fit is the right choice.
The seamless, ultra-light and woven mesh upper contains extra toe protection. This provides more strength and increases the durability of the upper. In addition, you can create the desired fit with the laces.
The midsole is made of FuelCell foam that provides exceptional energy return with every step. Of the entire New Balance sprint collection, the SD-X spikes contain the most foam. This ensures maximum energy return allowing the athlete to maintain his or her speed over longer sprint distances. The full-length carbon plate provides a stiff, responsive feel and powerful push-off.
To save weight and still provide enough traction, the 8 built-in pins are fused together with the outsole. This ensures ultimate strength and grip.
