I'm forming a hammer toe, how can i fix it?

Sometimes you can't: Be wise in your shoe selection that they acomodate and don'tmake it worse. Consider some form of strapping to hold the toe straight like a budin splint or the likes. Structural deformites often respond well to surgical correction.

Hammer toe: You can't 'fix' it . Buddy splinting is doomed to failure as it does not correct why the deformity is there in the first place. See your podiatrist for an evaluation and real help.

A contracted toe: A hammertoe is an contracture or a bending of the toe joint which results from a muscle or tendon imbalance due to the mechanical or structural changes in the foot. This can be hereditary or due to environmental factors such as tight shoes. This bending can lead to abnormal pressure distribution resulting in pain, swelling, blistering, and corns. Treatment can be conservative or surgical.
