New Balance SD100 v3
New Balance USD100 v4
Competition, beware. The New Balance SD100v3 is built for top-end speed.
New Balance designed the SD100v3 with a sock-like bootie upper that delivers a snug and secure fit, while a mesh forefoot allows your feet to breathe when the race heats up.
A forefoot plate with six removable spikes gives you superior traction and just enough rigidity, and a molded heel with a texture outsole gives you extra grip in the blocks. Perfect for the emerging sprinter, the New Balance SD100v3 is primed for a dynamic ride over the sprint distances.
