Feel the thrill, live the rush! Your all-new Women's Nike Pegasus Premium running shoe is the only Nike shoe with a unique triple layered midsole making it the most responsive Pegasus ever! Perfect for athletes who crave a fast, reactive run, this shoe combines ZoomX foam with a sculpted full-length Air Zoom unit (a first for the Pegasus line-up!) for springy cushioning that propels you forward. The ReactX foam offers a 13% boost in responsiveness, while the weight reducing mesh upper keeps you cool and light. The modified waffle outsole on your Pegasus Premium ensures solid traction so you can fly faster.
