The Cloud X 5 is On's gym and studio shoe, and this fifth version is notable for what On removed. The Speedboard is gone, replaced by deeper flex grooves and a new sculpted footbed so the foot can move naturally through a session, with a Helion superfoam midsole fine-tuned to balance that flexibility against stability. CloudTec cushioning is tuned for training rather than road running, and On says the midsole introduces CleanCloud, a foam the brand produces from captured carbon emissions, to this model for the first time. The upper is engineered open mesh for airflow, with extra padding through the tongue and collar, and the rubber outsole is patterned for side-to-side traction. On lists an 8 mm drop and about 290 grams in men's sizing.
Navy and Glacier is one of five men's colorways. On has this pair scheduled for September 3, 2026 at $160. It is the low-profile, everyday end of On's training range, a long way from the $250 Cloud X Tempo Pro, which keeps a full-length carbon Speedboard and a sled-specific Missiongrip outsole.
