The deep plantar arch is an important structure in the foot that is formed by the deep plantar artery, a branch of the dorsal artery. By examining the length of the foot and the positioning of the artery, one can make an estimation of where the deep plantar arch is situated. In addition to the deep plantar artery, there are also the lateral plantar arteries which traverse the metatarsal bones and connect with the dorsalis pedis artery. These arteries play a role in the formation of two types of arches – the transverse and the longitudinal arches.
The deep plantar venous arch plays a crucial role as the blood reservoir for the foot’s venous pump. Within this arch, two major pedicles can be found: the medial plantar artery and the lateral talus artery. These vessels serve the purpose of draining into the posterior tibial perforating vein, which subsequently gives rise to the anterior tibial artery. Unlike the first type of arch, this second arch is typically not visible and does not typically cause any symptoms.

The blood supply to the underside of the foot is supported by a deep plantar artery. Spanning from the fifth metatarsal bone to the first metatarsal bone, this artery ensures a steady flow of blood to this area. Additionally, the dorsalis pedis artery found on the top surface of the foot branches off to form the lateral plantar artery. Situated between the first and second metatarsals and surrounded by the first two metatarsal bones, this artery plays a crucial role in supplying blood to the foot.

The depth of a deep plantar arch varies between individuals. Researchers have found that the shortest distance from the distal epiphysis to the line passing through the deep plantar arch is 47.0 mm, while the shortest distance from the first metatarsal to the TMT joint is 18.6 mm. The lateral plantar artery is connected to the deep plantar artery.
The deep plantar venous arch is the true reservoir of the venous pump of the foot. It is composed of two large pedicles called the lateral and medial plantar arteries. These veins drain into the anterior tibial perforating vein, which gives rise to the posterior tibial artery. It also feeds into the peroneal artery, which originates in the distal part of the leg.
In a study comparing 100 human cadavers’ feet to a macaque’s foot, the arterial supply of the two arteries of the foot is similar. The superficial plantar arch is often shallow and thin. The arterial supply of the feet was compared with the lateral plantar artery in the same study. The lateral plantar artery is anastomosed with the deep plantar artery in 43% of cases.
The deep plantar venous arch is the true blood reservoir of the venous pump of the foot. The arch is composed of two large pedicles, the medial and lateral plantar arteries. The medial plantar artery is connected to the deep plantar artery and the lateral plantar artery, which gives rise to the posterior tibial vein. The anterior tibial artery is a small, three-to-four mm-wide vascular system. The peroneal artery arises in the distal portion of the leg.
The deep plantar artery is the real blood reservoir of the foot’s venous pump. It has two large pedicles, the medial and lateral plantar arteries. They connect to the posterior tibial perforating vein, which in turn gives rise to the anterior tibial vein. In addition to the posterior tibial artery, the peroneal artery is located in the distal portion of the leg.
The deep plantar artery runs from the fifth metatarsal to the first metatarsal and supplies the underside of the foot. The lateral plantar artery and the deep plantar artery branch from the dorsalis pedis artery run parallel to the arch. These arteries are responsible for providing the underside of the foot with blood. This arch provides the foot with essential blood.
The deep plantar artery is a branch of the dorsalis pedis artery. It supplies the first and second toe. The artery penetrates between the first and second metatarsal bones. It anastomoses with the terminal branch of the plantar arch. The lateral part of the plantar artery branches to the third and fourth metatarsal.
