The Queen of the Hill Drive Guides add an additional layer of feedback when used in conjunction with the Queen of the Hill Trainer. The guides fit on the mounting kit placed on either side of the back foot. When the pitcher launches forward, the guides should stay in the standard position. If they are misplaced after the pitch, you will know the foot position is incorrect and mechanical adjustments need to be addressed.
