I think the design of these changed along with the packaging -- they are now terrible. The product now does not stick in any of my footwear, nor does it grip my heels or make my footwear more comfortable to wear. In fact the product rubs against my skin causing blisters after finally making them stick in place with crazy glue. I made the mistake of ordering the second set thinking I ordered incorectly, but no, it was just the product. Don't waste your money on these.
