These are fantastic!
When I first wore the shoes I placed these in, I wasn't that impressed. But I recently ran out the door grabbing the shoes and forget all about the insert. When I got out of the car at my destination I thought 'wow, this insert is fantastic!'.  ( I wore the shoes the second time with bare feet and was worried about them sweating but it was good but it's cold outside so that my have helped a great deal). These are not designed to be repositioned- place them where you need and leave alone. A clean inside of shoe helps very much (my shoes were new) and mine are securely in place. These are also not intended to keep your foot from slipping forward-there's a different insert for that. These are not corrective either- if you have existing foot pain these will not make it magically go away. These are just to provide a little cushion at that spot under the ball of your foot where you put your weight on when you stand or walk and make heels more bearable. They did just that for me so I'm ordering more for my other heels.
