The GEL-KAYANO™ LITE 3 running shoe embraces a sound earth. With a greater emphasis on sustainability, this shoe keeps your step stable and your mind light. Its engineered mesh upper is made with a higher percentage of recycled polyester than the previous version. The collar and tongue’s recycled textiles are helping us take additional steps towards lightening our impact on the environment. FLYTEFOAM™ cushioning is made from organically derived materials. We added more of this lightweight foam in the forefoot to create a more energetic rebound at toe-off. The 3D SPACE CONSTRUCTION™ feature addresses the gait differences of male and female runners. It's designed to reduce overpronation, which keeps your foot supported.
