The soleus is one of the muscles within the superficial group within the posterior compartment of the leg. The soleus muscle is a large flat muscle which lies immediately deep to the gastrocnemius muscle.
The leg is comprised of anterior, lateral and posterior compartments. The posterior (flexor) compartment consists of two groups of muscles: a superficial group and a deep group, which are separated by a deep fascial layer.
