In the top side of the foot, adjacent dorsal digital arteries join to form the dorsal metatarsal arteries. While the dorsal digital arteries carry blood down from the small saphenous artery, and communicate with the plantar digital arteries in the clefts between the toes, the metatarsal vessels unite across the far ends of the foot (just above the toes) to form the dorsal arterial arch. On the sole of the foot, the superficial arteries form a plantar cutaneous arterial arch that extends across the root of the toes and opens at the sides of the foot into medial and lateral arteries.
