The Topo Athletic UltraFly delivers a natural ride for your daily training needs (road & light trail). Those running shoes bring serious cushion (A 3-Piece EVA Midsole), bounce and a touch of stability to Topo Athletic's low drop platform (28/23: 5mm drop for an easier/quicker transition), a roomy toe box and a light weight (283 g). The Ultrafly performed great in every run (long & short distance; easy & fast paced). Way to go Topo says Next-Feat. Team!
