Big performance. Small size. Designed for future milers and marathoners alike, the brand-new Clifton 9 Youth delivers the same disruptive performance features in a slightly smaller package. Approached through the lens of sustainability, HOKA have cued up an ultralight 50% sugarcane midsole, 31% rPET yarns derived with reduced water for less emissions, and high-abrasion rubber in targeted wear zones for enhanced durability.
