Introducing the Asics Gel-Kayano 31 - Asics most innovative support technology yet. Perfect for runners logging their daily kilometres or looking to increase their distances, the Asics Gel-Kayano 31 provides adaptive and holistic stability, combined with maximum cushioning to ensure full protection. Asics 4D Guidance System is designed to prevent overpronation, utilising wider basenets, an increased heel bevel, flared midsole geometry, a lateral guidance line, and a softer medial foam, reducing excessive motions which can be potentially harmful to a runners foot. With comfort at the forefront, Asics stacks the midsole of the Gel-Kayano 31 with full length FF Blast Plus Eco foam, Asics softest cushioning yet, and combines this with its rearfoot interior PureGEL technology to achieve soft landings and cloudlike comfort.
