      ASICS GEL-Cumulus 21 Men's Black/White

      The new Asics GEL-Cumulus 21 is back with impressive updates for the neutral runners who love reliable cushioning and comfort.

      A new contoured sockliner better matches the natural shape of the foot for a better fit.

      Bottom layer of the midsole features the FLYTEFOAM™ Lyte technology for better cushioning and comfort. Also, the grooves in the sole just under the heel have been adjusted for a softer landing.

      The collar has been modified with more foam and less adhesive for a more comfortable ankle wrap.

      The GEL-CUMULUS™ features the same last use in the GEL-KAYANO™ 25 and 26, with more height in the toe box and across the ball of the foot.

      Technology

      Upper: Features a multi-directional mesh that is knit in a way that provides more support in some areas and more space between the yarn in other areas to reduce the weight and enhance breathability.An internal heel counter provides support and stability. It is positioned between the internal and external fabric in the rearfoot to reduce the chance of irritation.

      Midsole: FluidRide® combines cushioning and lightweight responsiveness. Impact Guidance System (I.G.S.®) employs linked componentry to enhance the foot's 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.

      Outsole: Guidance Trusstic System® provides a lighter and stable outsole. AHAR® ASICS High Abrasion Rubber placed in critical areas provides exceptional durability.
