The best thing about them is also the worst - if you remove the sticker they'll stay put in your shoes but can't use in others.
These are soft gels that give some relief to heel pain due to heel spurs.  They fit my shoes reasonably well (my size is larger than the recommended size, so that's on me and I did not deduct for that), but their biggest asset is also their biggest detriment.<br /><br />They come with a sticker on the bottom of the cups. If you don't take the sticker off, they move around in your shoes.  If you take the sticker off, the bottom of the cups have a stick substance on them (it seems like the stuff that was on the toys that you'd throw at the wall and watch them slowly crawl down the wall).  When the sticker is removed and the sticky stuff hits your shoe, they stay in place very well, which is GREAT.  The downside is that if you remove them to put in a different pair of shoes, they will lose their stickiness and not stay well in any of your shoes.<br /><br />My advice is to put them in one pair of shoes and leave them there.  The problem is that this can become expensive if, like me, you want them in all your shoes.
