What is the cure for corns on my toes?

Hammertoe surgery. A hammertoe is an abnormal increased contracture or a bending of the toe joint. This most commonly results from a muscle or tendon imbalance which results from the mechanical and structural changes in the foot that may occur over time in some people. This abnormal bending can lead to abnormal pressure distribution causing a potential development of pain, swelling, blistering, and corns.
See below. Corns are caused by friction rubbing on the toe or between the toes. Wider shoes may help, trimming down the thick skin will help. Often there is a bone or bone spur involved and this may need to be removed.
