What modification should be added to a foot insert for hallux rigidus?

When managing hallux rigidus, which is characterized by a stiff big toe joint that restricts movement, the addition of a Morton's extension to a foot insert serves a critical purpose. This extension is designed to provide additional support to the first metatarsal while offloading pressure on the hallux or big toe. By extending the insert beyond the toe, it encourages a more stable weight transfer during ambulation, allowing individuals to push off the ground without placing excessive strain on the arthritic joint.

Using a Morton's extension helps in redistributing forces during gait, making walking more comfortable for individuals with hallux rigidus. This modification directly addresses the limitations caused by the condition, enhancing mobility and potentially alleviating discomfort associated with the limited range of motion.

While other modifications might address different aspects of foot function, they do not specifically cater to the requirements imposed by hallux rigidus and might not provide the necessary relief and support.
