Claw toes are classified based on the mobility of the toe joints. There are two types - flexible and rigid. In a flexible claw toe, the joint has the ability to move. This type of claw toe can be straightened manually. A rigid claw toe does not have that same ability to move. Movement is very limited and can be extremely painful. This sometimes causes foot movement to become restricted leading to extra stress at the ball -of-the-foot, and possibly causing pain and the development of corns and calluses.
