the shoes you choose should be chosen based on your squat stance. If you squat wide like the guys from Westside then Chuck Ts are best but if you squat conventional then a firm bottom with a wedge heel is best like a work boot, squat shoe, or olympic style shoe (my choice). A shoe that doesn't roll or have a spongy bottom is best for your knees and to keep you from falling forward. Check out www.usaweightlifting.org for their adidas weightlifting shoes.
