The soleus muscle is a muscle in the posterior (back) compartment of the leg. It is located just behind the gastrocnemius muscle, which is the larger, more visible muscle in the calf. The soleus muscle helps to plantarflex the foot, which means it helps to point the toes downward. It also helps to stabilize the ankle joint and support the body’s weight when standing or walking.
The soleus muscle originates from the posterior surface of the tibia and fibula bones in the lower leg and inserts into the calcaneus (heel bone) via the Achilles tendon. It is a relatively long, thin muscle that lies deep to the gastrocnemius muscle. The soleus muscle is active when standing, walking, running, and jumping, and it plays an important role in activities that involve movement of the foot and ankle.
Injuries to the soleus muscle are relatively uncommon, but they can occur as a result of overuse or trauma. Symptoms of a soleus muscle injury may include pain, swelling, and difficulty moving the foot or ankle. Treatment may include rest, ice, physical therapy, and medications to reduce inflammation and pain. In severe cases, surgery may be necessary to repair the muscle.
Function of the Soleus Muscle
The primary function of the soleus muscle is to plantarflex the foot, which means it helps to point the toes downward. This action occurs when the muscle contracts and shortens, pulling on the Achilles tendon and causing the foot to move downward.
In addition to plantarflexion, the soleus muscle also helps to stabilize the ankle joint and support the body’s weight when standing or walking. It works in conjunction with the gastrocnemius muscle and other muscles in the leg to help maintain balance and support the body’s weight.
The soleus muscle is active during activities that involve movement of the foot and ankle, such as standing, walking, running, and jumping. It also plays a role in activities that involve lifting the heel off the ground, such as climbing stairs or jumping.
Overall, the soleus muscle is an important muscle in the lower leg that helps to support and move the foot and ankle.
Common Issues with a Soleus Muscle
There are several common issues that can affect the soleus muscle. These include:
- Overuse injuries: The soleus muscle can become strained or inflamed as a result of overuse, particularly in people who engage in activities that involve a lot of movement of the foot and ankle, such as running or dancing. Symptoms of an overuse injury may include pain, swelling, and difficulty moving the foot or ankle.
- Trauma: Trauma to the leg, such as a fall or a direct blow, can also cause an injury to the soleus muscle. Symptoms may include pain, swelling, bruising, and difficulty moving the foot or ankle.
- Tendinitis: Tendinitis is an inflammation of the tendon, and the soleus muscle has a tendon that inserts into the heel bone. Tendinitis of the soleus muscle can cause pain and swelling in the lower leg, as well as difficulty moving the foot or ankle.
- Strain: A strain is a stretching or tearing of the muscle fibers. This can occur as a result of overuse or trauma. Symptoms of a strain may include pain, swelling, and difficulty moving the foot or ankle.
- Tear: A tear is a more severe injury that involves a complete rupture of the muscle fibers. This can occur as a result of a traumatic event, such as a fall or a direct blow to the muscle. Symptoms of a tear may include severe pain, swelling, bruising, and difficulty moving the foot or ankle.
If you are experiencing pain or other symptoms that you think may be related to the soleus muscle, it is important to see a healthcare provider for a proper diagnosis and treatment. Treatment may include rest, ice, physical therapy, and medications to reduce inflammation and pain. In severe cases, surgery may be necessary to repair the muscle.

- Tear: A tear is a more severe injury that involves a complete rupture of the muscle fibers. This can occur as a result of a traumatic event, such as a fall or a direct blow to the muscle. Symptoms of a tear may include severe pain, swelling, bruising, and difficulty moving the foot or ankle.
If you are experiencing pain or other symptoms that you think may be related to the soleus muscle, it is important to see a healthcare provider for a proper diagnosis and treatment. Treatment may include rest, ice, physical therapy, and medications to reduce inflammation and pain. In severe cases, surgery may be necessary to repair the muscle.
How to Rehab your Soleus Muscle
If you have an injury or condition that affects your soleus muscle, it may be necessary to undergo rehabilitation to help the muscle heal and regain strength. Rehabilitation typically involves a combination of rest, physical therapy, and exercises to help improve flexibility, strength, and function of the muscle. Here are some general guidelines for rehabbing your soleus muscle:
- Rest: It is important to allow the muscle to rest and heal after an injury or surgery. This may involve limiting or avoiding activities that place stress on the muscle, such as running or jumping.
- Ice: Applying ice to the affected area can help to reduce inflammation and pain. Ice should be applied for 15-20 minutes at a time, several times a day.
- Physical therapy: Physical therapy can help to improve flexibility and strength in the soleus muscle. A physical therapist can develop a customized treatment plan that may include stretching, strengthening exercises, and other techniques to help the muscle heal and function properly.
- Gradually return to activity: As the muscle begins to heal, it is important to gradually increase activity levels to allow the muscle to adapt and become stronger. This may involve starting with low-impact activities and gradually progressing to more strenuous activities as the muscle becomes stronger.
It is important to follow the guidance of a healthcare provider or physical therapist when rehabbing a soleus muscle injury or condition. They can provide specific recommendations and guidance to help ensure a successful recovery.
