Fine tune your speed with the Sigma Harmony. With a lighter, sleeker upper and a new full length spike plate, the Harmony was designed to help bring finesse to distances under 400m. Inspired and tested by athletes like Trayvon Bromell, the new spike plate creates a smooth but powerful transition underfoot. A knit heel and sleek upper construction provide structure where you need it with simplicity where you don’t. This is pure, primal speed.
