A tip-of-the-spear product geared for elite athletes, the new Cielo X 3 MD has been overhauled with refinements underfoot and a newly designed upper. Utilizing a new, super critical foaming process combined with a slightly stiffer Pebax spike plate, this new iteration delivers a snappier, faster ride. Engineered specifically for middle distance racing (800m-3K), weve employed an ultra-light, lace-knit upper for a breathable, race-ready fit.
