The Loop is a delicate, strappy slide. This sandal has gore at both sides of the instep for adjustability. Naot's anatomic cork & latex footbed is wrapped in leather with a microfiber center to prevent slipping and molds to the shape of the foot with wear. The Avantgarde Collection features a TPR sole with a metal shank. This sole offers the look of a 2" heel without the feel. This is a perfect wedding shoe or other special event shoe.
