Directly from Tory Burch - The shape of a wishbone - a symbol of luck - embedded in its sole. Designed for forward momentum. because luck is what you make of it. Symbols of luck from around the world have always fascinated Tory. The evil eye, knocking on wood and, a family tradition, carrying a red ribbon whenever she travels.  Our trainer combines flattering lines and comfort: a deep ankle scoop that elongates the leg; an oversized ergonomic sole for lift; and our Double T logo set at an angle. Innovative construction balances support and softness. A structural wishbone within the cushioned midsole acts as a cambrion, reinforcing the shoe's internal support system. Tory Burch Official Site.
