These felt adhesive-backed U-pads are the perfect easy solution for taking the pressure off of one painful, sore corn or callous on the bottom of the foot. The pads are 1/8 inch thick. The pads can relieve pressure from a painful corn or callous up to 5/8 inch thick and 3/4 inch length. The pads should be removed before showering and bathing. Patients have told me they can get the pads to stick for about two days in a row before they have to discard it. I have been recommending these pads to patients for years and have found they are terriffic for releiving pressure from one sore calloused spot.
