These pads for the bottom of my feet are made from a silicone and are supposed to give support. You slide the pad on by putting your toe through the loop, but the pad moves around a lot in the shoe and while I would love to give a good review for these pads, I have to say that they are not something I would purchase again.
The silicone pad is supposed to give support but actually feels like it is a wad of rubbery silicone moving around in my shoe and it hurts worse with the pad in my shoe, than without it.
The pads are a one-size-fits all, and appear to be well made. Since they are designed to give relief, and not only did they not provide relief but they actually hurt worse, I simply can’t recommend them. Perhaps if you have something different wrong with your feet, they might work for you, but they didn’t for me.
