What to look for Causes Treatment What to look for Hammer, mallet and claw toes are common and often painful deformities of the feet. All of these conditions can cause painful corns and calluses if they rub on shoes.

Mallet toes are bent down at the end joint only. Claw toes are toes that are bent down at both the middle and end joints and bent up at the joint closest to the foot.
