ASICS GEL-Cumulus 21 GTX running shoes are here to upgrade your rainy-day runs! A Gore-Tex® membrane shields your feet from puddles and rain, keeping you dry and comfortable no matter how soggy the terrain. The bottom layer of the midsole features FLYTEFOAM™ Lyte technology for better cushioning and comfort, and the grooves in the sole just under the heel have been adjusted for a softer landing. All of these features combine to give you a cloud-like run mile after mile.

Upper: Features a multi-directional mesh that reduces overall weight and enhances breathability. Gore-Tex® technology keeps feet dry in wet conditions. 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 more stable outsole. AHAR® ASICS High Abrasion Rubber placed in critical areas provides exceptional durability.
