Sandal Life Care Kit is specially formulated to penetrate & thoroughly remove dirt, oils & perspiration from neoprene, rubber & fabric footbeds as well as nylon webbing and leather straps. Why clean your sandals? Because most people do not wear socks with sandals and your feet perspire up to one-half pint per day. Perspiration permeates the soles & straps of sandals and causes deterioration. Regular care will keep your sandals clean & fresh and make them last longer. Good grooming applies to bare feet and sandals too. Your friends & others will appreciate it.
