PUMA Mobium Elite Mens Running Shoes Synthetic Lightweight breathable mesh upper with synthetic overlays for support Uniquely sculpted, IMEVA midsole expands and contracts along with the movement of your foot to mimic the "windlass mechanism" Mobium Band, a finely tuned elasticised band that runs through the outsole in a figure eight design, mimics the foot's tendons, so the more force applied, the more spring it returns Expansion Pods in the outsole mirror the foot's own bones and fat pads delivering added cushioning, protection, and flexibility just where you need it Evertrack technology in the outsole, which incorporates high abrasion-resistant carbon rubber, provides durability in high-wear areas
