High-Arched Feet (Cavus Foot): Causes, Problems, and Treatment

Medically reviewed by Dr. Tom Biernacki, DPM — Board-Certified Podiatric Surgeon — Balance Foot & Ankle, Howell & Bloomfield Hills, MI. Last updated April 2026.

High-arched feet (pes cavus) are significantly underappreciated as a source of foot pain and injury. While flat feet receive considerable attention in podiatric discourse, cavus foot deformity creates its own spectrum of predictable problems — including lateral ankle instability, stress fractures, peroneal tendon pathology, plantar fasciitis, and metatarsal pain — that respond to targeted treatment once the underlying foot type is recognized as the contributing factor.

What Is Cavus Foot?

Cavus foot describes a foot with an abnormally high medial longitudinal arch, typically accompanied by hindfoot varus (the heel tilts inward), forefoot equinus (the forefoot is plantarflexed relative to the hindfoot), and often claw toe deformity. The arch elevation concentrates weight bearing on the heel and the lateral forefoot metatarsal heads — a narrow, rigid load distribution that contrasts sharply with the broader, shock-absorbing contact of a normal arch.

Neurological Causes Must Be Excluded

Approximately 50–60% of progressive cavus foot deformity has an underlying neurological cause — most commonly Charcot-Marie-Tooth (CMT) disease, the most common hereditary peripheral neuropathy. Other neurological causes include Friedreich’s ataxia, cerebral palsy, poliomyelitis, spinal cord lesions, and spinal dysraphism.

Bilateral progressive cavus deformity — particularly developing in adolescence or young adulthood — should prompt neurological evaluation. Idiopathic cavus foot (no identifiable neurological cause) accounts for the remaining cases and often has a strong familial pattern.

Common Problems Associated With Cavus Foot

• Lateral ankle instability: The heel varus positions the foot in a permanent mild inversion — reducing the mechanical resistance to ankle rolling and dramatically increasing lateral ankle sprain frequency. Patients with cavus foot have significantly higher rates of chronic ankle instability than the general population.
• Peroneal tendon pathology: Peroneal tendon tears, subluxation, and tendinopathy are associated with cavus foot from the chronic supination load on the peroneal tendons
• Fifth metatarsal stress fractures and Jones fractures: The lateral load distribution of cavus foot concentrates stress on the fifth metatarsal — explaining the higher Jones fracture rate in this foot type
• Plantar fasciitis: The rigid, high-arched structure places chronic tension on the plantar fascia at rest and under load
• Metatarsal stress fractures: Lateral metatarsal stress fractures from the narrow forefoot contact area
• Claw toe deformity: The intrinsic muscle imbalance of cavus foot progressively worsens claw toe deformity

Conservative Treatment

Custom orthotics for cavus foot require specific design features distinct from flat foot orthotics:

• Lateral forefoot posting to fill the space under the elevated lateral column
• First metatarsal head cut-out to accommodate the plantarflexed first ray
• Lateral heel wedge to correct hindfoot varus
• Full-length cushioning to offset the reduced intrinsic shock absorption of the rigid arch

Supportive footwear with adequate cushioning and a stable heel counter is equally important — the minimalist, zero-drop footwear often marketed as beneficial is particularly problematic for cavus foot patients.

Surgical Treatment

Progressive or severe cavus deformity that fails conservative management may require surgical correction, tailored to the specific deformity components: plantar fascia release, first metatarsal dorsiflexion osteotomy, calcaneal osteotomy for heel varus correction, claw toe correction, and lateral ankle ligament reconstruction for associated instability.

Most Common Mistake We See

The most common mistake we see is: Wearing new orthotics all day from day one. Fix: break-in schedule of 2 hours on day one, adding 2 hours per day until full-day tolerance.
