I wouldn't expect it to work for everybody, due to different foot lengths and technique. In my case, my foot is long enough that the beater head on rebound stroke... the beater head gets right into the "V" of the ankle, but no cigar on any contact. If my feet were a half inch shorter, then it might be a problem.
