Abstract: A unique biomechanical exercise and conditioning device for rehabilitating the ligaments, tendons, and muscles in the foot and lower leg with the purpose of alleviating heel and foot pain, which can lead to heel spurs. The exercise and conditioning device comprises a single, spherical surface that spins about a rod that has been set into a box. Approximately, one-third of the upper portion of the sphere is positioned above the top of the box. The user will place one foot on the sphere, press down upon it, and roll the affected foot across the sphere repeatedly. This motion will massage and stretch the foot. This action will help to loosen tight membranes and muscle fibers in the foot that cause pain when a person stands on the affected body part.
