Which shoe modification is commonly used to relieve pain associated with hallux rigidus?

The modification that is commonly used to relieve pain associated with hallux rigidus is the met rocker. This design feature helps facilitate more natural movement at the forefoot, promoting a smoother transition during walking. The met rocker allows the foot to pivot around the metatarsal heads, reducing pressure on the rigid joint of the big toe. This is particularly beneficial for individuals suffering from hallux rigidus, where pain and discomfort occur due to limited mobility in the joint.

The met rocker essentially increases the range of motion at adjacent joints and can help redistribute forces away from the affected area, thereby alleviating pain and enhancing comfort during ambulation. The design encourages a continuous rolling movement of the shoe, helping to offset the limitations caused by the stiffness associated with hallux rigidus.
