Drew Summer Mary Jane Shoes - a timeless favorite improved with added depth Get the comfort you need with the classic style you want in this versatile Mary Jane. If you use custom orthotics, simply remove the polyurethane insole for added depth. A firm heel counter and tempered steel shank work together to provide support and help enhance walking stability. Plus, a flexible and lightweight rubber outsole moves with you. Subtle stitch detailing adds visual interest to the leather upper, and a buckled instep strap offers adjustability. Orthotic-Friendly.
