The Nike Free Run 5.0 Running Shoes blend an incredibly flexible minimal outsole for more natural movement with the cushioning traction and lightweight support of a traditional running shoe. The upper is made from a lightweight knitted mesh with Flywire technology on the midfoot for ultra light ventilation and a dynamic fit that moves with your foot for greater momentum. Hexagonal flex grooves are hot-knife cut into the outsole and wrapped around the sidewall so your foot can move more naturally in all directions. The heel is designed to mimic the shape of your foot and it rolls with the ground to deliver a more natural footstrike and the sleek grey design is finished with the signature Nike swoosh to the side. - L.R.
