Arcopedico Special Edition Lolitas Color Cool Curve Size 40=9-9.5 The hallmark of all Arcopédico shoes can be seen in two fundamental design principles: the “barefoot” upper, a soft, non-binding design that conforms to the top of the foot to allow circulation and all-day comfort, and the patented, metal-free twin arch-support soles (made from molded polyurethane), which protect the foot arch and allow the distribution of body weight through the entire plantar surface.
