Slides forward BUT did bring great relief to plantar fasciitis . Easy to take out and slip into your different shoes, have tried in leather chelsea boots and various runners for work (in healthcare and need to switch from inside outsideshoes). Glad I tried it before dishing out on otherwise more expensive custom orthotics (though I'm sure those would be of great benefit as well!) . Plan to buy more- an economical way to manage plantar fasciitis for the time being.

I have bought a couple of of these and have absolutely loved them! I remove the regular insoles from my running shoes and put these in. I have had 2 pairs of these for years! Whenever they start to smell after maybe a year's use, I toss them into the washing machine and pull out the other pair and put them in my shoe and let the other ones air dry. Then they are ready at a moment's notice when I need to wash the other pair again. I can see that someone complained in the reviews here about the insole sliding around in their shoe. I find if I just make sure to push the insole to the back of the shoe before sliding in my feet and lacing, I basically have no problems. It needs to be pushed to the back of the shoe though before lacing! If the insole pulls forward even a tiny bit while putting in your foot, then the sliding will happen. I put a finger down on the insole as I'm sliding my foot in and put pressure towards the back of my shoe. As you can see from my pics, these are well loved! LOL! I'm afraid that they will stop selling them when I need to replace them! Invaluable product! I have high arches and one collapses to the side, so these are a life saver!

I liked these for a while, they were very comfortable to walk with, but the sticky bit on the heel of one insole wore out and the insole started slipping forward in my shoe. It became uncomfortable to walk with it all pushed forward to the front of my shoe, and the heel pad not under my actual heel. Tightening my shoelaces didn't help.
