It is a medical term that you probably have never heard of, but it's more commonly known as a bunion. Hallux refers to the big toe, and Valgus is a term meaning an outward angle.
Bunions are caused when the big toe shifts and points towards the other toes. This causes the metatarsal bone to protrude on the inner side of the foot. When this bone shifts this way, it starts to rub on the inside of shoes and causes swelling and eventually leads to more bone to form at the joint, compounding the issue.
While there is some research that shows genetics have some affect, the most common cause of bunions is the choice of footwear. In children and adults that rarely wear shoes, you will see that big toe points straight and maybe even a little away from the rest of the toes. This is the natural position for the big toe.
Most footwear is designed to stabilize the toes and squeezes them together causing the big toe to be pushed away from it's natural position. The more fashionable the shoes, the more likely they are going to push the toe further and further out of alignment.
If you already are having issues with bunions, The Original Foot Alignment socks can help to move the big toe back away from the other toes and help straighten them out, while also stretching the other toes.
If you haven't started having issues with bunions or other foot pain issues, wearing foot alignment can help prevent the movement of the big toe and provide non-surgical relief from many other foot issues such as hammer toes, crooked toes, plantar fasciitis and more. We have even had customers tell us that they relieve from mild neuropathy where the normal treatment process is to use drugs to deaden the nerves.
