Featuring an updated outsole and upper design, the Nike Zoom Pegasus 34 is crafted to keep you light on your feet and absorb impact with each and every step. Grooves cut into the stabilizing crash rail allow for natural range of motion, while the waffle pistons and radiused heel design promote balance. An updated Flymesh upper delivers lightweight ventilation and support so you stay quick on your feet, while Zoom Air units deliver responsive cushioning.
