Your foot has four small toes called phalanges, each with three joints, and a big toe called the hallux, with two joints. Your toes connect to your mid-foot, which connects to your hind foot. The 20 muscles of your foot connect the intricate network of bones and permit you to walk, stand and pivot on your feet. Because of the incredible weight you place on the small foot muscles, tightness can easily develop, resulting in cramps and pain.
