These running shoes are designed with a rounder heel to accommodate the shape of a woman's foot. A lightweight stretch mesh upper provides a comfortable, foot-hugging fit, and a midfoot cage locks in the foot for stability through every mile. I have purchased these exact sneakers a few times over the years. My husband bought me a new pair and he threw away the box...the problem is I needed a 6.5 and since these are a 6 they are a little small, so they are still new, never been worn and in great condition.
