Enhance your workout time outdoors with Nike's innovative and patented Free Trail 5.0 running shoe. Developed to optimize foot extension for serious and competitive runners the Free 5.0 series emphasizes a light deep flexing shoeless sensation that strengthens your feet with the same natural range of motion you would experience running barefoot. The big differences you'll find in the Free Trail 5.0 are the stabilizing Transpan along the upper the low-profile Phylon midsole with a bit more cushion for uneven surfaces and an aggressive outsole (by Free 5.0 standards) with extra rubber grip pods and lugs for more traction.
