Anyone use these custom, moldable insoles? (Read 393 times)

I know I see that some people here use over the counter insoles like Superfeet. I was wondering in any uses these insoles that you heat and custom mold to your feet: http://www2.yoursole.com/home.html I saw a podiatrist yesterday and he gave me some Powerstep insoles to try for a week to see if it helps with my knee pains, but I was digging around today and I was wondering if these moldable inserts would be better that a "generic" insole.
