The Ankle Tac Tic The Ankle Tac Tic was designed to give the same feedback to a player who sways the lower body like a tennis player and breaks down the right ankle. The ANKLE Tac Tic clicks when the ankle bends. This will cause the player to loose power from the coil and slice the ball. The lower body is the foundation to a powerful and consistent golf swing. The lateral hip movement swaying on the lower body weakens a player's foundations. Weight transferring to the outside at the right back foot is a result of swaying. Practicing with the ankle Tac Tic will teach a player to keep their weight on the inside of the right back and get rid of their sway. Once a player has learned to keep a solid lower body foundation they can build a powerful golf swing. Eliminates swaying. Keeps weight on the inside of the back foot. Helps build a solid lower body foundation. If you have any questions about this product or would like to order by phone, please call us Toll Free at 888 733 8383. We look forward to hearing from you!
