I rode with PowerGrips for quite some time and liked them a lot. I found them easy to get in/out of once they were adjusted just right. I had to swap them for regular clips & straps though because my left foot kept going numb when riding (I've had problems with circulation in my left foot ever since crushing it in an auto accident 12 years ago).
Haven't a lot of people been ripped off by Hold Fast? Am I thinking of another company?
