Hallux rigidus is a condition that causes pain at the first metatarsophalangeal joint due to arthritis and bony spurring. Pain is found on the dorsum of the first mtp joint, especially with extension. The hallux (great toe) must extend approximately 65 degrees for normal gait. Insufficient range of motion results in compensatory pronation to allow the body to pass over the foot during the propulsive phase of gait. These faulty foot biomechanics only place additional stresses on this joint.
A over the counter to balance the biomechanics and a rocker sole being added to the bottom of the shoe should provide relief. Carbon fiber foot plates are also used to limit motion in this joint.
If you think you suffer from this condition please contact a medical specialist.
