This boot has padded technical lining for comfort, warmth and moisture absorption. Naot's removable, anatomic cork and latex footbed is wrapped in microfiber and leather and molds to the shape of the foot with wear. The Aura Collection features a 1.5" polyurethane sole with a metal shank which is extremely lightweight, durable and abrasive to prevent slipping. This collection uses a hand-sewn Strobel construction making it strong and extremely flexible. Our patented Naot Replacement Footbeds are available for Boreas.
