Worn for 10 minutes basically brand new with Box (see heel that is perfect and slight discoloration on bottom); decided the color was not for me and couldn't return. These are super comfy and do run small, I usually wear a size 5.5. Design details: maximum cushioning, two-piece apl futurefoam midsole specifically tuned for running. slanted shank plate encourages forward motion upon foot strike. lightweight, solid rubber outsole designed for road and gym use.
