I was just at a Meijer store (similar to Wal-Mart) and in the medicine section, next to the blood pressure machine, there was a huge display for Dr. Scholl's. Here is this gigantic computer, you stand on it, and it starts running. Well, it has a pressure sensitive pad and shows how you distribute weight on your feet! I learned that my normal stance has me putting all the weight on my heels.
Considering I already have anterior pelvic tilt, this means I actually need to lean just a bit forward and get more quad drive. I know the insoles are mostly useless, but the display is cool, and it's free to try out. Knowledge is power.
