The GEL-KAYANO™ LITE 3 running shoe embraces a healthy planet. With a greater emphasis on durability, this shoe keeps your step steady and your mind light. The engineered mesh upper is made with a higher percentage of recycled polyester than the previous version. The recycled textile of the collar and tongue helps us take extra steps to reduce our impact on the environment. FLYTEFOAM™ cushioning is made from organically derived materials. We've added more of this lightweight foam in the forefoot to create a more energetic rebound at push-off. The 3D SPACE CONSTRUCTION™ feature addresses the running differences between male and female runners. It is designed to reduce overpronation, supporting your foot.
