What is the function of Morton's extension in foot orthotics?

Morton's extension is specifically designed to relieve pressure under the metatarsal heads, particularly beneficial for conditions such as metatarsalgia. This extension extends the material of the orthotic beyond the metatarsal heads, providing a redistribution of pressure across the forefoot. This helps to alleviate pain and discomfort that patients may experience in the ball of the foot. By shifting the load away from the sensitive metatarsal areas, Morton's extension contributes to a more comfortable walking experience.

In contrast, enhancing arch support, stabilizing the ankle joint, or adjusting heel height are functions that do not directly relate to the specific purpose of Morton's extension. Each of these functions plays a role in foot orthotics but addresses different concerns, like overall foot alignment, stability while walking, or correcting leg length discrepancies. Therefore, understanding that Morton's extension primarily targets metatarsal pressure helps clarify its unique role in foot orthotics.
