Foot Supination: Symptoms, Causes, Tests, and Treatments
Updated May 8, 2023
Often overlooked, the foot plays a crucial role in our overall well-being. Many foot issues, such as supination, remain unaddressed. Also known as underpronation, supination occurs when the body's weight falls on the outer side of the foot, increasing the arch and making the ankle unstable. During a normal gait cycle, the foot should slightly pronate, allowing the arches to flatten and cushion body weight. In a supinated foot, however, the outer edges of the foot bear most of the weight.
Here is what you need to know about foot supination:
Understanding Supination Symptoms
Supination symptoms include:
- Ankle pain
- Calluses or bunions on the outer edge of the foot
- Shin splints
- Ankle sprains
- Pain in the ball of the foot
Can Supination Cause Knee Pain?
A supinated foot can cause inner leg muscle weakness, outer leg muscle tightness, and reduced shock absorption. Supination has been linked to increased incidences of knee pain, ankle pain, and plantar fasciitis (Achilles Tendonitis), but no direct relationship between ankle sprains and foot type has been found.
Causes of Foot Supination
Foot supination can result from genetic factors, muscle imbalances, poor foot biomechanics, past trauma to the ankle and foot, ill-fitting shoes, overuse during sports or physical activities, joint stiffness, or degenerative diseases like osteoarthritis.
Assessing and Addressing Supination
Early diagnosis and treatment are crucial in combating foot supination. Simple self-assessment tests can help identify this condition. Additionally, a physical therapist can provide a thorough diagnosis by analyzing your gait and using the Foot Posture Index (FPI-6) to measure the degree of supination.
How to Perform Self-Assessment
The quickest and easiest way is to examine your old shoes and pay attention to the pattern of the edges. If the outer edges of your shoes are worn out, you're most likely a supinator.
Another way to check your feet for supination is to paint or wet your feet and stand on a paper of contrasting color with your entire weight. If you find out that the arch of your feet is minimally outlined or not visible, your foot is likely supinated.
Effective Treatment Options for Supination
Supination can cause muscle imbalances that lead to pain in the hips, knees, and back. A conservative approach to treatment includes physical therapy sessions, orthotics, and insoles. Exercises, such as calf and hamstring stretches, plantar fascia stretches, and core strengthening, can help alleviate pain and improve stability.
Customized running shoes or shoe inserts can provide adequate support and cushioning to reduce friction and improve overall balance. In rare cases, reconstruction surgery might be necessary for those with excessive supination. Consult a doctor or podiatrist to rule out any other contributing factors.
NOTE: Consult your doctor or podiatrist to rule out any other causes contributing to your foot condition.
Foot Health with Balance and Stability
Foot care should not be overlooked, as issues like supination can cause pain, imbalanced gait patterns, and discomfort while walking or running if left unmanaged. Early diagnosis, proper treatment, and prevention can help manage this condition and improve overall foot health. To enhance your comfort and support, explore Footora's selection of insoles specifically designed for supination. Give your feet the care they deserve and experience the difference that custom-fit insoles can make.
