The soleus is a muscle within the superficial compartment of the posterior leg.

It is a flat muscle located underneath the gastrocnemius, and gets its name from its resemblance to a sole – a flat fish.

  • Attachments: Originates from the soleal line of the tibia and proximal fibula. The muscle converges with the fibres of the gastrocnemius to form the calcaneal tendon, which inserts onto the calcaneus.
  • Actions: Plantarflexion of the foot at the ankle joint.
  • Innervation: Tibial nerve
  • Blood supply: Posterior tibial artery
