Plantar venous network

On the sole of the foot the superficial veins form a plantar cutaneous venous arch which extends across the roots of the toes and opens at the sides of the foot into the medial and lateral marginal veins.

Proximal to this arch is a plantar cutaneous venous network which is especially dense in the fat beneath the heel; this network communicates with the cutaneous venous arch and with the deep veins, but is chiefly drained into the medial and lateral marginal veins.
