A hammertoe is a toe that is bent all the time because of a weakened muscle. The weakened muscle makes the tendons (tissues that connect muscles to bone) shorter, causing the toes to curl under the feet. They can be hereditary and can also be caused by shoes that are too short.
This is a condition in which the foot has a very high arch.
This is a condition in which the upward bending motion of the ankle joint is limited.
Rheumatoid arthritis (RA)
