The IB702 features the Island Pro Black Lug sole and original foot bed design, with the arch, heel cup, and outside contour. The upper is crafted from oiled leather and lined with neoprene for comfort. After a short break-in period, the soft EVA insole will self-mold to your foot's unique shape. If you are looking for lots of mileage and a slipper that lasts, this is the one for you. Made in Hawaii USA.
