Morton’s extension is soft or firm padding that extends from the first metatarsophalangeal joint (MPJ) to just beyond the interphalangeal joint. On your custom orthotic, it limits the range of motion for the first MPJ.
Alternatively, a Morton’s extension in shell is available and is frequently used for Turf Toe. We recommend using polypropylene plate material. This accommodation is often used for severe hallux rigidus, sesamoid fractures, or to promote a more rigid hallux when a transmetatarsal buttress is needed.
Reverse Morton’s extension is padding that is proximal to the second through fifth first metatarsophalangeal joints extending to the sulcus. The first first MPJ is channeled out. The padding is made from a firm material like DURAform™, but can be made with other materials. This can help promote dorsiflexion of the hallux.
