The Naot Koa is a slip on shoe. This style has a padded heel cup for support and functioning stretch at the instep for accessibility. This style has padded technical lining at the front which provides comfort, warmth and absorbs moisture. Naot's removable, anatomic cork and latex footbed is wrapped in pampering suede and molds to the shape of the foot with wear. The Koru Collection features a 1'' polyurethane sole which is extremely lightweight, durable and slip resistant. This collection uses a hand-sewn stroble construction making it strong and extremely flexible.
