Cavus Foot (High Arch): Complete Guide to Causes, Symptoms, and Treatment

What Is Cavus Foot?

Cavus foot, also known as high arch foot or pes cavus, is a structural condition in which the arch of the foot is significantly higher than normal. Unlike flat feet, where the arch collapses inward, cavus foot features a rigid, exaggerated arch that does not flatten with weight-bearing. This creates an abnormal distribution of body weight, with excessive pressure concentrated at the heel and ball of the foot. The result is a range of symptoms that can affect the entire lower extremity.

Causes of Cavus Foot

Cavus foot can be either structural (idiopathic) or neurological. Understanding the underlying cause is critical because it determines treatment and prognosis.

Neurological causes account for approximately two-thirds of cavus foot cases. Conditions that affect the nerves and muscles of the foot — including Charcot-Marie-Tooth disease, cerebral palsy, spina bifida, polio, and spinal cord tumors — can create muscle imbalances that pull the foot into a high-arch, claw-toe position. In any patient with cavus foot, evaluation for an underlying neurological condition is essential.

Idiopathic or structural cavus foot occurs without an identifiable neurological cause. It may be inherited and is often first noticed in childhood or adolescence.

Symptoms and Related Problems

Lateral ankle instability: The high arch creates a supinated foot position that shifts weight to the outer border of the foot, making lateral ankle sprains extremely common. Many cavus foot patients have a history of recurrent ankle sprains.

Metatarsalgia and calluses: The increased pressure under the ball of the foot (metatarsal heads) causes chronic pain and thick callus formation.

Heel pain: Concentrated heel strike pressure can cause plantar fasciitis or heel stress fractures.

Stress fractures: The fifth metatarsal (the outer foot bone) is particularly vulnerable to stress fractures in cavus foot patients due to lateral loading.

Claw toes: Muscle imbalance causes the toes to curl downward at the middle joint, creating painful corns and difficulty finding comfortable footwear.

Peroneal tendon problems: The peroneal tendons, which run along the outer ankle, can become overstressed and develop tendinopathy or tears.

Diagnosis

A podiatrist evaluates cavus foot through physical examination, assessing arch height, foot flexibility (rigid vs. flexible cavus), toe deformities, and ankle stability. Weight-bearing X-rays measure the pitch of the calcaneus and the Meary angle (relationship between the talus and first metatarsal) to quantify arch elevation. A neurological evaluation is arranged when an underlying condition is suspected.

Non-Surgical Treatment

Custom orthotics with lateral wedging and metatarsal padding redistribute pressure from the heel and ball of the foot across a wider surface area. Ankle bracing reduces instability and sprain risk. Proper shoe selection — shoes with wider, more stable bases and adequate cushioning — is essential. Physical therapy addresses muscle imbalances and proprioception deficits.

Surgical Treatment

When conservative measures fail, surgical correction is considered. Procedures depend on the severity and rigidity of the deformity and may include plantar fascia release, osteotomies (bone cuts) to reposition the heel and metatarsals, tendon transfers to rebalance muscle forces, and toe corrections for claw deformities. Surgical outcomes are generally good when the procedure is properly matched to the deformity.

Cavus Foot (High Arch) Treatment in Michigan: Orthotics, Bracing, and Surgical Correction

Michigan patients with cavus foot — high arch deformity producing lateral foot overload, ankle instability, peroneal tendon stress, and metatarsalgia — benefit from evaluation that identifies both the structural deformity and its neurological cause when one is present. Charcot-Marie-Tooth disease and other hereditary peripheral neuropathies are a significant cause of progressive cavus foot deformity, and recognizing the neurological basis of a patient’s cavus foot affects both the treatment approach and the family screening implications. At Balance Foot & Ankle, cavus foot evaluation includes Coleman block testing to distinguish forefoot-driven from hindfoot-driven deformity — a distinction that guides surgical planning when operative correction is indicated. Conservative treatment with custom orthotics and bracing is the foundation of cavus foot management; surgical correction with calcaneal osteotomy, metatarsal osteotomy, and plantar fascia release is appropriate for patients with rigid deformity and pain or functional limitation not addressed by conservative care. Michigan cavus foot patients can call Balance Foot & Ankle at (810) 206-1402 to schedule a comprehensive evaluation at our Howell or Bloomfield Hills office.
