This casual leather slip-on gives feet just what they need. The Drew Plus Fitting System® offers the choice of removing one or two of the insoles for added or double depth, providing room to use a custom orthotic if needed. A firm heel counter and tempered steel shank work together to provide support and help enhance walking stability. Plus, a flexible and lightweight polyurethane outsole moves with you. The fit is easy to adjust with a hook-and-loop Z-strap over the instep. Orthotic-Friendly.
