Experience zero gravity in these lightweight, supremely comfortable women's running shoes. They are built with a boost™ midsole for great cushioning that doesn't sacrifice groundfeel. Plus, boost™ doesn't pack out or stop feeling springy, even after months of use. An EVA outsole combines with the boost™ midsole to keep every step charged with light, fast energy. The shoe's Primeknit upper hugs your foot like a second skin for a snug comfortable fit that moves with your natural range of motion.
