The Kumara is a great, everyday lace up shoe. This style has a slightly padded tongue and a padded heel cup for additional stability & comfort. The front portion of the Kumara features padded technical lining which provides comfort and absorbs moisture. Naot's removable, anatomic cork & 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 & slip resistant. This collection uses a hand-sewn stroble construction making it strong and extremely flexible.
