Calima is a fashionable flat bootie with three decorative straps and buckles. There is an inner zipper for easy entry, and the buckles allow for some adjustment. The removable, anatomical 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 polyurethane sole with a metal shank which is extremely lightweight, durable and abrasive to prevent slipping. This collection uses hand-sewn Strobel construction making it strong and extremely flexible.
