Parts of feet are the various components that make up the human foot. ARCHES (6 letters) are the curved structures on the bottom of the foot that help to support the body's weight and provide flexibility. Insteps (7 letters) are the top part of the foot, located between the toes and the ankle. Soles (5 letters) are the bottom of the foot, which is in contact with the ground when walking. Littletoes (10 letters) are the smallest toes on the foot, usually located at the end of the foot.
