The new ASICS GEL®-Cumulus 20 running shoes feature new improvements that make the running experience even more enjoyable! While still a mid-level neutral, cushioned running shoe, this new installment is even lighter than its predecessors, but includes a more responsive ride because of an EVA foam addition to the FlyteFoam® midsole cushioning. A flexible, stretch mesh upper and a more roomy toe box provides a more comfort, adaptive fit. For those looking for a more plush ride, check out ASICS’ max cushion neutral running favorite, the Nimbus 20. Upper: Flexible upper design features engineered mesh and no-sew overlays that stretch, hug and move with the foot. Padded tongue and heel collar enhance comfort. Midsole: FluidRide® combines cushioning and lightweight responsiveness. Impact Guidance System (I.G.S.®) employs linked componentry to enhance the foots natural gait from heel strike to toe-off. GEL® Cushioning Systems attenuate shock during impact and toe-off phases, and allow movement in multiple planes as the foot transitions through the gait cycle. FlyteFoam® Midsole technology is lightweight and provides long lasting, responsive cushioning. Added EVA foam provides and even more responsive ride. Outsole: Guidance Trusstic System® provides a lighter and stable outsole. AHAR® ASICS High Abrasion Rubber placed in critical areas provides exceptional d urability.
