I just want to know has anybody had problems with using blue superfeet in their snowboard boots? I have very flat feet and my feet and ankle tend to get sore very quickly. I was looking to buy footbeds to solve this problem, however, I was on the Superfeet website, and it indicated that "The support ridges in the bottom of the Blue cap can grind into the Gore-Tex boot lining". I was wondering if this issue will make the superfeet insole grind into my boot liners? Anybody had that problem with their blue superfeet in their boots??
