The human foot represents a remarkable feat of natural engineering, comprising 26 bones that work in harmony to support body weight and enable mobility. This detailed lateral view illustration demonstrates the intricate arrangement of foot bones, from the ankle to the toes, showcasing how these structures interconnect to provide stability, flexibility, and support during standing, walking, and other activities.
Essential Components of Foot Bone Anatomy
Fibula The fibula is one of the two lower leg bones that extends to the ankle. This slender bone provides lateral stability to the ankle joint and serves as an attachment point for multiple muscles.
Tibia The tibia is the main weight-bearing bone of the lower leg. It forms the upper portion of the ankle joint and plays a crucial role in transferring body weight to the foot.

Talus The talus is the primary ankle bone that articulates with the tibia and fibula above. This uniquely shaped bone distributes body weight between the leg and foot while enabling ankle movement.
Navicular The navicular bone is located between the talus and cuneiform bones. It plays a vital role in maintaining the medial arch of the foot and provides attachment for important ligaments.
Cuneiforms The three cuneiform bones form part of the midfoot structure. These wedge-shaped bones articulate with the navicular posteriorly and the first three metatarsals anteriorly.
Cuboid The cuboid bone is situated on the lateral side of the foot. It articulates with the calcaneus and fourth and fifth metatarsals, playing a crucial role in lateral foot stability.

Calcaneus The calcaneus, or heel bone, is the largest foot bone and forms the posterior pillar of the foot arch. This bone bears significant weight during standing and walking while providing attachment for the Achilles tendon.
Metatarsals The five metatarsal bones form the framework of the forefoot. These long bones connect the ankle bones to the phalanges and help distribute weight during walking.
Phalanges The phalanges are the toe bones, with three in each toe except the big toe, which has two. These bones provide leverage for forward propulsion during walking and help maintain balance.
