The Formal is the perfect slide heel for all of your festive events! This sandal has a hook & loop instep strap so you can create the perfect fit. The Formal has gore at the middle strap to allow for additional adjustability. The delicate rivet accents make this shoe stand out from the crowd. 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.
