The Naot Francine is a flat, toe thong sandal with gore at the instep for adjustability. The toe thong is made from soft nubuck to avoid irritation & has padded technical lining for extra comfort. The inside of the instep has a full strap for extra support. Naot's anatomic cork & latex footbed is wrapped in a pampering suede and molds to the shape of the foot with wear.
