The Asics GEL-KAYANO 30 embraces a sound earth. With a focus on sustainability, this shoe keeps your step stable and your mind light. The engineered mesh upper is made with a higher percentage of recycled materials than the previous version. Its structure also targets key support zones to increase stability. FLYTEFOAM® cushioning is made from organically derived materials. This lightweight foam improves shock absorption during the landing phase of your stride. 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.
