The IG8111 features the Island Pro non-marking Deck Sole and original foot bed design, with the arch, heel cup, and outside contour. The upper is made from soft cotton webbing that is wider than the traditional nylon web. For the insole we have used two great products from Rubatex Rubber and Torray UltraSuede in a combination that provides superior flexibility and shock absorption, with the soft feel of suede that is durable and water washable. If you are looking for instant and long lasting comfort, this is the one for you. Made in Hawaii.
