"Does anyone know of another franco sarto pump, with a back on it instead of slingback, that shares this exact design including a strap across the top? I am looking for basically the same shoe but not a slingback. I like this shoe and I can rarely wear a heel without an open toe, something about it works for my toes if I add a no-slip gel pad on ball of foot. Fairly comfortable given it is a heel, a 1.5-2 hour shoe for me. :) very cute on."
