Tight shoes are the most common cause of these toe problems. Wearing tight shoes can cause the toe muscles to get out of balance.
If a shoe forces a toe to stay in a bent position for too long, the muscles tighten and the tendons shorten, or contract. This makes it harder to straighten the toe. Over time, the toe muscles can’t straighten the toe, even when you aren’t wearing shoes.
These toe problems form over years and are common in adults. Women are affected more often than men because they are more likely to wear shoes with narrow toes or high heels.
