The ASICS Gel-Cumulus 21 GTX is a Gore-Tex lined neutral training shoe that’s made for running in cold, wet and snowy conditions. This year’s version has been improved with more volume in the forefoot and better cushioning in the midsole and around the heel collar. The midsole has been updgraded to lighter and more resilient Flytefoam Lyte for a softer, springier ride, while the new multi-directional mesh upper enhances this shoe’s durability.
