The importance of medial arch support for flat feet

Biocorrect, LLC


The medial arch, or medial longitudinal arch, is simply the term for one of the three major arches in the foot, with the other two being the lateral longitudinal arch and the transverse arch. Together, the three arches form a triangle across the bottom of the foot that provides critical support while allowing for the full range of foot movement we need every day. 

Running along the length of the inside of each foot, the medial arch is probably what you think of when you hear someone talk about the arches of the feet. And if you’ve been diagnosed with flat feet, or low arches, then it is primarily because of a flat medial arch. Having flat feet is common, and not always painful, but it can cause increased soreness and injury risk for many people who have it. That’s where medial arch support for flat feet can help. 

If you’re looking to learn more about the benefits that high-quality orthotics can offer, we’re happy to share the following guide. 

Why medial arch support for flat feet is so important

People diagnosed with low medial arches often suffer from an issue known as overpronation. Properly aligned and functioning feet should rotate inward with each step, helping to load the forefoot like a spring to propel forward. This motion is known as pronation. 

However, without a strong medial arch, the feet can have a tendency to rotate inward too far, or overpronate. This extra motion can put increased strain on the feet and all the way up the lower body, leading to an increased risk of pain and injury, including: 

  • Sore feet and ankles
  • Plantar fasciitis 
  • Achilles tendinitis
  • Knee pain 
  • Hip pain
  • Lower back pain

Medial arch support for flat feet can help reduce the amount of inward rotation and promote the natural mechanics of the lower body.
