Work great!
I've purchased a few heel cushions over the years and I've experienced problems with them not sticking properly to the shoe or not working the best at keeping the shoes in place.  These stuck great and are very comfortable.  They work well and I had no issues with them.  I've used them on a couple of pairs of shoes I have issues with and I wear them to work every day.  I've had them for some time now and they still work.  Would buy again.
