I did see the game changers on YouTube or some other site, but I was a bit skeptically of me molding them the wrong way. Do they give a lot of support, or do they just simply fit to your foot.
You can't really mold them the wrong way. Put water in, put the insole in a shoe and walk around for a few minutes. The upside is that they mold to your arch exactly the right amount and stay like that.
I don't really know what you mean by asking if they give a lot of support. They fit your foot. I believe the support mainly comes from the boot.
