Run strong, run fast with the trusted support and stability of the ASICS GEL-Kayano 24, because you shouldn't have to sacrifice speed in order to get the stability and structure you need as an overpronator. The GEL-Kayano 24 delivers both by combining the ultra-lightweight, ultra-responsive cushioning of FlyteFoam midsole technology with an array of stability features that help guide your foot through a natural stride from heelstrike to toe-off. FluidFit? upper construction combines multi-directional stretch mesh with supportive reinforcements for a snug fit that adapts to your foot and moves with you. Heel Clutching System holds the foot securely in place over the footbed. ComforDry X-40 sockliner prevents the growth of odor-causing microbes to keep feet fresh. FlyteFoam midsole technology for bouncy, responsive cushioning that returns energy with every step for a faster running stride. Guidance Line Midsole Technology uses a vertical flex groove to encourage a more natural running gait. DuoMax Support System uses a dual-density midsole to provide areas of enhanced support and stability so you can run with confidence. Rear- and forefoot GEL Cushioning Systems absorb and disperse the shock of impact for a more comfortable run. Impact Guidance System uses linked componentry to help limit pronation and encourage a smooth transition from heelstrike to toe-off. ASICS High Abrasion Rubber in high-wear areas of the outsole for durable traction where you need it most. Wt. 9.2 oz.
