This isn't the best picture, considering my right thigh was falling off a little bit, but this is the only picture I have right now that shows my shims
I used a white trashcan for the material of my shims. The thigh shims are glued down on one side with E6000, and the other side is attached with velcro. I decided not to glue both sides since its easier for me to put them on this way.
My calve shims are also made from trashcans, and are velcroed into place on both sides. Basically its the same exact set up as shown here:

Hope this helps!
