The Finer Details A foam midsole delivers a soft, smooth ride. There’s a little more room in the forefoot compared to the 6, as well, so your toes don’t feel cinched or pinched. Nike added puffs to the heel that are visible on the outside of the shoe. They're soft to the touch and help add comfort to your Achilles. Touch points at the tongue create a natural feel as you take off. The outsole sports a generative traction pattern that combines with rubber lugs to help give you grip when going uphill or downhill.
