Moleskin is a soft fabric with a thin layer of felt attached to a
sticky backing. It is used most often on the feet to protect the skin from
rubbing against itself or footwear and is also used to help cushion the
feet.
After an affected area is washed and dried, the sticky side of
moleskin can be applied so that it covers the area. Moleskins can protect
blisters when they are cut in a ring shape that encircles the blister. The
adhesive should not be stuck to broken or raised skin.
