The IBL8903L features the Island Pro Black Lug Sole and original foot bed design, with the arch, heel cup, and outside contour. The upper is cut from a beautifully tooled cowhide with a rich supple feel. For the insole we have combined the Rubatex Rubber and the same tooled cowhide for an unbeatable leather feel and durability. If you are looking for instant and long lasting comfort with the unmistakable look of finely tooled leather, this is the one for you. Made in Hawaii USA.
