A triangular thickening of the deep fascia of the sole that protects the underlying nerves, vessels and muscles.

Key points

• Calcaneal tubercles → five slips to the toes.
• Protects the sole’s nerves and vessels.
• Plantar fasciitis → calcaneal spur.
• Connective tissue: from leftover mesenchyme.
• Dense CT: irregular (capsules) or regular (tendons, ligaments).
