plantar fasciitisI have been suffering with heal pain in the bottom of my foot for some time and have used a variety of over the counter insoles which did not really help. My chiro suggested these. While I still have some pain these have helped the most of any I have tried. They cushion the heal and you can stack two on top for additional comfort. One con is that there are no instructions on the package and you have to figure which way to insert them. There is three marks on the outer edge of both heal cups on the same side. Seems like the mark should be on the opposite side for left and right. I can definitely tell when they are not inserted correctly as it is not comfortable. I ended up flipping one of the cups upside down so the outter edge was on the outside of my foot and it was fine. The other con is they don't really adehere to shoe and can slide around. I tried using tape but they still moved around.I’m a tennis player and coach. I’m on the court 3 to 5 hours a day. These heal cushion are a perfect addition to my sport insoles. I like that they are not that bulky and thick. They add just enough extra cushion to the cushion that my insoles provide! The horseshoe shape is also perfect as it supports you heal in just the right places and the don’t slip around!T h ese inserts don't work very well at all they have a tendency to slide down to about the middle of my foot right under the the arches making it terribly uncomfortableEasy to use.I have a heel spur in the same foot that I also deal with Achilles tendinitis. I ordered these specifically for the heel cup for my spur and the little extra ‘lift’ they offer for my Achilles. Being the first heel cups I have ever tried, I have no comparison, however, they do increase the comfort for my heel and ankle. What I really like about these is that they fit in my ballet flats where most inserts don’t. I wish the adhesión to my shoe was just a little better, sometimes I have to take my shoe off and readjust the insert. Overall, pleased with the product.I have heel bone pain and have struggled to find inserts that alleviate the pain from walking. These are helping! They're inexpensive, arrived promptly and fit comfortably. They do appear to help my the pain. The silicone -- unavoidably -- has friction and so I need to take care putting my shoes (and slippers) on so as not move the insert. My only feedback is that I think I'd prefer them to be even deeper but this may be because I'm a tall man.It fulfills the function, it’s comfortable and works for all the shoes!!!I was very disappointed with these. I thought they would have a lot more 'give' or 'cushion' when worn but, unfortunately, for me it was like walking on solid rubber.These stay in place and gel is soothing, although wish they were thicker. Placed one on top of the other to achieve a softer result for my heel. Overall still good though.Talons douloureuxI m full satisfied there service
