The Progress heel will make you stand out! This style features delicate rivet accents on a padded front strap. The Progress has a padded heel cup & hook & loop ankle strap. 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.
