The Naot Lan is a flat slip on shoe. This style has a heel cup for stability and support and crisscross stretch for accessibility. Naot's removable, anatomic cork and latex footbed is wrapped in leather and molds to the shape of the foot with wear. The Aura Collection features a 1.5'' polyurethane sole which is extremely lightweight, durable and abrasive to prevent slipping. This collection uses a hand-sewn stroble construction making it strong and extremely flexible.
