Painful conditions of the forefoot can often benefit from rigid carbon plate insoles that make the shoe stiffer to restrict motion and decrease pain. This is particularly helpful for osteoarthritis or hallux rigidus of the hallux joint, turf toe and Freiberg’s infarction.
There is two different types of these rigid carbon plates based on their width in the forefoot. The full width one is rigid across the entire forefoot where as the one with what is called a Morton’s extension only goes under the big tie which allows the other side of the forefoot to have some more movement.
These inserts are only 1.0 to 1.2mm thick so easily fit into the shoes without any issues. They do change the way you walk, so may take a while for people to get used to wearing them.
