Actually I've been using those gel thingys but they cost everytime so I wanted to find a better way. I like the feel of them though.
I was talking about it at the car shop today and one guy suggsted car thermal insulation. It is a mylar foil with a squishy core, all about 1/8 inch thick. I traced out an insole and it initially felt better than the original for squish and it felt warm instantly. I still have to test them, but if it works then that is soo cheap It cost me nothing to do it with shop scrap, but the stuff is so cheap at stores anyhow.
I'll let yall know how it goes.
