The IG8103F features the Island Pro non-marking Deck Sole and original foot bed design with arch, heel cup, and outside contour. The upper is crafted in our Tiger fabric with suede lining in an extra wide strap for comfort and support. 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.
