The J-Glove is the only shooting aid on the market designed to teach a user how to correctly grip, set up, and release a basketball. By promoting proper biomechanics of shooting, the J-Glove uses finger splint design technology in preventing premature finger flexion at the base of the finger joints - which is the #1 reason for improper side to side wrist mechanics during follow through. Additionally, the finger splint design creates absolute perfect shot set up, never allowing the ball to rest on your palm. All this, without any additional pad/foam as with other rival training aids.
