There's more than meets the eye in the exceptionally comfortable Naot Lava Shoe, and that's a good thing for the foot. The insole, covered with a layer of soft, spongy suede, consists of a proprietary combination of condensed natural cork granules, latex, and jute for a highly shock-absorbent insole that conforms to the shape of your foot and reduces back stress. Polyurethane soles are non-skid, lightweight, and flexible. Leather uppers; two side gores for easy on/off. Imported.
