Built for speed. Cushioned for comfort. An entry level spike engineered with more cushioning and midsole foam than our elite spikes, the Crescendo MD is built for speed with a 6-pin spike plate and race-ready single-layer mesh upper. Engineered with the thickest stack height you’ll see on the track; this beginner-friendly spinoff is bound to turn heads on the starting line whether racing your first 4x400 or two-miler.
