Great for those shoes that are 1/4 too big.
The pads arrived earlier than expected which was awesome. And they fit perfectly into my shoe. The top heel part did not stick too well to my shoe but that's because my hEel was lined with felt and it's very hard to stick something to felt, but it wasn't something a little super glue couldn't fix. I'm giving it the full five stars because it solved both my problems: my shoes were 1/4 size too big and the heel was uncomfortable for my 6 hour standing shift at work. Also it was great that they are invisible because they can barely be detected when my shoe is off and is not visible when it is on.
Rating: 5 stars
