ASICS GEL-Kayano 26 Men's Running Shoes Mantle Green/Olive Canvas : The new ASICS Gel Kayano 26 running shoes feature the following new benefits for runners who want a supportive and luxuriously comfortable training shoe: FLYTEFOAM(TM) Propel technology in the forefoot and directly under the heel provides a springier feel. More aggressive sculpting of the rearfoot foam and GEL(TM) technology for better sheer deformation and increased impact protection and a smoother transition to toe-off. The GEL(TM) technology cushioning unit in the heel was inspired from the shoe's storied past for a softer lay down at heel strike. Runners who like the fit of the Kayano 25 with its taller toe box and more accommodating width will love the carry over into version 26. Composition Upper: Features an engineered jacquard mesh that is knit in such a way to provide added support in some areas while in others there is more space between the yarn to reduce weight and enhance breathability. Midsole: FluidRideA(R) combines cushioning and lightweight responsiveness. Impact Guidance System (I.G.S.A(R)) employs linked componentry to enhance the foot's natural gait from heel strike to toe-off. GELA(R) Cushioning Systems attenuate shock during impact and toe-off phases and allow movement in multiple planes as the foot transitions through the gait cycle. FlyteFoamA(R) Midsole technology is lightweight and provides long-lasting, responsive cushioning. Outsole: Guidance Trusstic SystemA(R) provides a lighter and stable outsole. AHARA(R) ASICS High Abrasion Rubber placed in critical areas provides exceptional durability.
