Shoes with straps are notorious for rubbing and causing discomfort. Strappy Strips are designed to make all your 'Strappy' problems go away. Strappy Strips are made from a very cushy material called PORON. You peel and stick the strips right where you need them. Add the padding to those thin straps or keep your slingbacks in place. Of course, Strappy Strips are completely hidden from view. Foot Petals has several other products designed to make your shoes fit better and more comfortably.
