Plantar metatarsal arteries
They run forward between the metatarsal bones and in contact with the Interossei.Each divides into a pair of plantar digital arteries which supply the four webs and the adjacent sides of the toes.Near their points of division each sends upward an anterior perforating branch to join the corresponding dorsal metatarsal artery.The digital branch for the lateral side of the fifth toe arise from the lateral plantar artery near the base of the fifth metatarsal bone.This article incorporates text in the public domain from page 640 of the 20th edition of Gray's Anatomy (1918)
