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 to take additional steps towards lightening the impact on the environment. Flytefoam cushioning is made from organically derived materials. Asics 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.
