I use SuperFeet in my regular/casual shoes for arch support. Typically use the green insoles. Purchased the yellow insoles for my MTB shoes, and they seem great. Have been using them for a month now and no complaints. Great product.

These are ridiculous. I can't believe I got sucked into the hype of these. They sell them in stores in big displays, their information sounds good. I can only guess that other purchasers have had to convince themselves there's a difference at all, because there isn't one. If I hadn't trimmed these to fit my shoe bed (cycling shoes), and if I had time to pack and ship them, I'd return them.
Best Uses: Leveling a wobbly table
Cons: No difference whatsoever, Overly-hyped, Save your money
