Insoles are hit or miss. I currently use superfeet which is a considerable upgrade over the foam insoles that come in your boot. But for what you get for $50 with the superfeet, I would recommend spending an extra $50 to get custom molded insoles. If you spend a lot of time on the hill it's def worth the investment. And if you don't spend that much time on the hill they can last you for years.
i was just looking at the super feet and the size range is from 9.5-11 and 11.5-13. My boot is an 11. I am not sure if my foot is done growing. would i be able to fit he 11.5 in my boot or can i cut it?
