The new Gel Kayano 22 introduces full-length FluidRide® midsole technology for the first time in ASICS youth-specific running collection — a shoe built specifically for developing athletes. ComforDry™ X-40 Sockliner with anti-odor properties for a cooler, drier, healthier environment. FluidRide™ midsole technology combines the ultimate bounce-back and cushioning properties with reduced weight and exceptional durability. DuoMax® Support System consists of a dual-density midsole positioned to enhance support and stability for performance. Guidance Trusstic System® integrates Guidance Line® technology to enhance gait efficency and provide structural integrity through the midfoot. Heel and forefoot GEL® Cushioning Systems absorb and disperse shock during impact and toe-off phases, allowing natural foot movement as you move through the gait cycle. Guidance Line® technology in the outsole employs vertical flex grooves to decouple the tooling along the line of progression for enhanced gait efficiency and performance.
