The CenterLine® Foot Corrector’s spring tension will challenge the beginner to advanced practitioner. It effectively works the muscles of the foot by raising it off the floor to aid alignment, as well as working the leg and pelvis. The saddle is an excellent size to open the sole horizontally as well as laterally. The saddle holes have space around the posts so that the foot muscles learn to grab the surface and work correctly in order to make no noise. All this enables full body connection. Tone and balance the body from the sole up!
