I agree with the above poster. A raised heel shoe isn't going to help with butt-tuck (aka butt-wink) or feet rolling in. Those are form issues that require you to drop the weight and spend some time retraining your body. For butt-tuck I found that I really need to focus on pushing my ass out, which in turn causes an unpleasant stretch in my front quad/hip flexor. Apparently this is where my issues is. The positive effects are that the bar stays over my heels better and it prevent the forward "dump" feeling that causes you to want to rock onto the balls of your feet.
