The HOKA Cielo X1 3.0 is an elite-level, lightweight road racing shoe designed for maximum speed and energy return, featuring a propulsive, winged carbon fiber plate sandwiched between responsive PEBA foam. Released in early 2026, it offers a refined, breathable leno-weave upper, improved stability with a redesigned, less aggressive heel rocker, and a durable outsole for high-pace, long-distance performance.
