They work as the should
They do what I need them to do.  I have a pair of heels that slide off the back of my heal when I walk.  I used the medium sized heal liner and they no longer slide off.  However, they do not stick well to the shoe and the top of the liner rolls slightly and sticks to my tights.  Not sure how long they will stay in my shoe.  They need better’s adhesive
