High Arches: Why They Hurt and How to Support Them
A high arch (pes cavus) is the opposite of flat feet — the arch is raised, so weight is carried mainly on the heel and the ball of the foot with little contact in between. This concentrated loading can lead to pain, calluses and instability.
What is a high arch?
With a high arch, the midfoot sits well off the ground and the foot tends to roll outward (underpronation or supination). Because less of the sole shares the load, the heel and forefoot absorb more pressure than they would in a neutral foot.
Causes
Some high arches are simply inherited foot shape. Others are linked to neurological conditions affecting the muscles that balance the foot. A high arch that appears or worsens in adulthood, especially on one side, should be assessed to rule out an underlying nerve issue.
Common problems
- Pain under the ball of the foot and heel
- Calluses from concentrated pressure
- Ankle instability and a tendency to roll the ankle
- Claw or hammer toes
- Increased stress-injury risk in runners
Support strategies
Unlike flat feet, high arches need cushioning and shock absorption more than motion control. Look for neutral, well-padded shoes and consider cushioned arch-filling insoles that increase total contact area. Ankle-strengthening exercises help with instability.

Frequently asked questions
- Do high arches need support?
- Yes — cushioning and full-contact insoles help spread the concentrated load on the heel and forefoot.
