High arch is an arch, sometimes called the “pes cavus,” that is raised more than normal. The arch runs from the toes to the heel on the bottom of the foot. High arch is usually caused by a bone or nerve condition. Highly arched feet tend to be painful, because more stress is placed on the section of the foot between the ankle and toes.
Diagnosing High Arched Feet
When the person stands on the foot, the instep looks hollow. Most of the weight is on the back and balls of the foot (metatarsals head).
Your podiatrist will need to check to see if the high arch is flexible, meaning it can be moved around.
Tests that may be done include:
- Electromyography
- MRI
- Nerve conduction studies
- X-ray of the feet or spine
Treatment Options
High arches, especially ones that are flexible or well-cared for, may not need any treatment. Corrective shoes may help relieve pain and improve walking. This includes changes to the shoes, such as an arch insert and a support insole. In severe cases, surgery to flatten the foot is sometimes needed.
