The GEL-Kayano® 23 shoe features our revolutionary FlyteFoam™ Technology for the optimal balance of lightweight cushioning comfort for a luxurious ride. The FluidFit® upper leverages seamless stretch mesh reinforcements to increase forefoot support, while adapting to the foot's natural motion to create a custom sock-like fit. Our Forefoot and Rearfoot GEL® Cushioning Systems absorb shock upon impact to equip overpronators with a smooth and effortless transition between heel strike and toe-off phases.
