Which posterior tibial artery branch supplies the heel?

Explanation:
Blood to the heel comes from calcaneal branches of the posterior tibial artery, and the medial calcaneal branch specifically enters the heel region to supply the calcaneus and surrounding soft tissues. The medial plantar branch serves the medial sole and toes, not the heel; the dorsalis pedis artery runs on the dorsum of the foot; the lateral plantar branch mainly supplies the lateral plantar surface and helps form the plantar arches. So the medial calcaneal branch is the one that supplies the heel.
