Edit: Forgot to mention, I use these wedges on my left foot only, don't seem to have any problems since installation. It solved a problem I had with pronating of the knee.
I use these on my right leg also to correct a pronating knee. The right leg is longer than the left so we shimmed the left with opposing shims to create an even wedge on both sides of the foot. So far so good. Took 2 hrs to get everything to "fit" so i think it should be good to go.
