The Pioneer is a beautiful 2" heel with a unique leather design. This slide has hidden gore at the instep for a comfortable fit. 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.
