Hammer toes are a common foot deformity characterized by abnormal bending or curling of one or more toes, giving them a hammer-like appearance. This condition can result from multiple factors, including muscle imbalances, improper footwear, trauma, or certain medical conditions. Symptoms of hammer toes may include toe deformity, pain or discomfort, especially when wearing shoes, difficulty flexing or straightening the affected toe(s), and the development of corns or calluses on the top of the toe joint.
