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.
