The Naot Superior is a lace up boot. Naot's removable, anatomic cork and latex footbed is wrapped in pampering suede and molds to the shape of the foot with wear. The Executive Collection features a 1.75" TPR sole. This collection uses a hand-sewn Strobel construction making it strong and extremely flexible. Our patented Naot Replacement Footbeds are available for Superior. Plus, it's American Podiatric Medical Association (APMA) accepted for promoting good foot health.
