Quick Answer:
Quick Answer: Pes cavus (high-arched foot) is a structural deformity with excessively high medial longitudinal arch causing lateral border overload, ankle instability, and recurrent lateral ankle sprains. A significant percentage of cavus feet have an underlying neurological cause (CMT disease, Friedreich’s ataxia) — neurological evaluation is essential. Symptomatic cavus responds to custom lateral-post orthotics and physical therapy. Surgical correction (osteotomy, tendon transfers) is reserved for progressive deformity or failed conservative care.
Pes cavus — high-arched foot — is a complex structural deformity characterized by elevation of the medial longitudinal arch, hindfoot varus, forefoot pronation, and claw toe deformity. Unlike flatfoot, cavus foot presents a rigid, stiff foot that concentrates load at the heel and lateral forefoot rather than distributing it across the foot. At Balance Foot & Ankle PLLC, Dr. Tom Biernacki provides comprehensive cavus foot evaluation — including neurological assessment — and treatment for Michigan patients.
Neurological Evaluation is Essential
A significant portion of cavus feet — estimates range from 60–70% — have an underlying neurological etiology. Charcot-Marie-Tooth (CMT) disease is the most common cause of progressive cavus deformity. Friedreich’s ataxia, spinal cord abnormalities, and cerebral palsy also produce cavus patterns. Any patient with progressive cavus, claw toes, or bilateral symmetric deformity requires neurological evaluation. EMG/nerve conduction studies and genetic testing (PMP22 gene for CMT) are appropriate. Identifying the neurological cause is critical because progressive neurological disease will continue to produce deformity regardless of orthotic or surgical intervention.
Clinical Presentation
Lateral border overload: callus formation under the 5th metatarsal head and lateral heel. Recurrent lateral ankle sprains from varus hindfoot (increased risk of inversion injuries). Claw toe deformity from intrinsic muscle weakness. Peroneal tendon overload. Plantar fascia tightness and heel pain. Metatarsal stress fractures from concentrated lateral forefoot loading. Coleman block test: determines whether hindfoot varus is flexible (corrects with forefoot positioning) or rigid — guides surgical planning.
Treatment
Conservative: custom orthotic with lateral heel wedge and metatarsal support to redistribute load medially. Wide toe box footwear to accommodate claw toes. Ankle bracing for instability. Surgical (for progressive or symptomatic failure of conservative care): Calcaneal osteotomy (Dwyer — lateral closing wedge to correct hindfoot varus). Dorsiflexion osteotomy of 1st metatarsal (corrects plantarflexed 1st ray). Plantar fascia release. Peroneus longus to brevis transfer (reduces plantar-flexion force on 1st ray). Extensor tendon transfer/Jones procedure (corrects claw toes and strengthens ankle dorsiflexion).
Dr. Tom's Product Recommendations
Powerstep ProTech Orthotic
⭐ Highly Rated | Foundation Wellness Partner | 30% Commission
Firm-arch orthotic with lateral post — provides lateral heel and forefoot support for cavus foot. Helps redistribute load from the lateral border to a more normal distribution.
Dr. Tom says: “My podiatrist prescribed lateral-posted orthotics for my high-arched feet and these were a good OTC starting point before my custom orthotics.”
Cavus high arch, lateral border overload, lateral heel posting, claw toe support
Custom orthotics with precise lateral posting are superior for structural cavus correction

New Balance 990v6 Stability Shoe
⭐ Highly Rated | Foundation Wellness Partner | 30% Commission
Classic stability running shoe with wide base — provides good lateral support for cavus foot. The firm midsole accommodates custom orthotics and provides cushioning for the high-pressure lateral forefoot.
Dr. Tom says: “My foot doctor recommended a firm stable shoe for my cavus feet and the 990 has been excellent for both everyday use and running.”

✅ Pros / Benefits
- Neurological cause identified in majority of progressive cavus cases — enables coordinated care
- Custom lateral-post orthotics effectively redistribute load for symptomatic relief
- Comprehensive surgical ladder addresses all components of complex deformity
- Coleman block test guides appropriate surgical planning for hindfoot correction
❌ Cons / Risks
- Progressive neurological cavus will continue to deform despite orthotics or surgery if underlying disease progresses
- Surgical correction is complex — multiple procedures often required simultaneously
- Rigid cavus deformity has limited correction potential without bony surgery
Dr. Tom Biernacki’s Recommendation
High-arched feet are underdiagnosed and frequently misunderstood. The first thing I do with a cavus foot patient — especially one with progressive deformity or family history — is neurological evaluation. CMT disease is the underlying cause in a substantial number of these patients. Once the neurological picture is understood, the treatment approach is individualized to the degree of deformity, the patient’s activity demands, and whether the disease is stable or progressive.

Frequently Asked Questions
What causes a high-arched foot?
High-arched (cavus) foot has neurological causes in the majority of progressive cases — Charcot-Marie-Tooth disease, Friedreich’s ataxia, and spinal cord conditions. Non-neurological causes include prior compartment syndrome, residual clubfoot, and idiopathic. Any patient with progressive cavus deformity or bilateral symmetric presentation should undergo neurological evaluation including EMG and genetic testing.
Can orthotics fix a high-arched foot?
Custom orthotics cannot structurally correct cavus deformity but effectively manage symptoms by redistributing load from the overloaded lateral border to a more normal distribution. Lateral heel posting and metatarsal support reduce callus formation, lateral ankle instability, and peroneal tendon overload. For stable, non-progressive cavus, orthotics provide excellent long-term symptom management.
What is the Coleman block test?
The Coleman block test assesses whether hindfoot varus in cavus foot is driven by the plantarflexed first ray (forefoot-driven) or is fixed in the hindfoot. Standing on a block that elevates the medial forefoot: if the hindfoot varus corrects — it is forefoot-driven and correctable with 1st metatarsal osteotomy. If the hindfoot stays varus — it is fixed and requires a calcaneal osteotomy. This test guides the surgical approach.
Should I see a neurologist for my high-arched feet?
If your cavus foot is progressive (deformity worsening over time), bilateral and symmetric, or associated with leg weakness, difficulty walking, or family history of foot deformity — yes, neurological evaluation is strongly recommended. CMT disease is common and treatable in terms of managing progression, even if the deformity itself requires surgical correction. Dr. Biernacki coordinates neurological referral as part of comprehensive cavus evaluation.

How long does treatment take to work?
Most patients see improvement in 4-8 weeks with consistent conservative care. Persistent symptoms after 8 weeks need imaging and escalation.
When is surgery needed?
Surgery is reserved for cases that fail 3-6 months of conservative care, structural deformities, or fractures requiring stabilization.
Is this covered by insurance?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Custom orthotics often require diabetic or post-surgical justification.
