What Is Cavus Foot?
Cavus foot (pes cavus) describes a foot with an abnormally elevated medial longitudinal arch. Unlike flat feet, which are extremely common and often idiopathic, cavus foot is frequently neurological in origin — the most common cause is Charcot-Marie-Tooth disease (hereditary motor and sensory neuropathy), accounting for approximately 60–70% of progressive cavus cases. Other neurological causes include Friedreich’s ataxia, spinal cord tumors, spina bifida, and cerebral palsy. The high arch develops as weak intrinsic foot muscles are overpowered by stronger extrinsic muscles, progressively pulling the foot into plantarflexion and varus. At Balance Foot & Ankle, Dr. Tom Biernacki evaluates every cavus foot patient with a systematic approach that includes neurological screening.
Clinical Features and Associated Problems
Cavus foot creates a characteristic cluster of associated problems. Hindfoot varus — the heel turning inward — predisposes to repetitive lateral ankle sprains and chronic ankle instability. Claw toes develop as intrinsic muscle weakness allows the long extensors and flexors to become deforming forces. Forefoot pronation drives the first metatarsal head into the ground, causing first MTP overload and sesamoid problems. Peroneal weakness contributes to a foot-drop-like gait pattern. Lateral column overload causes stress fractures of the fifth metatarsal — a classic complication of cavus foot. The rigid, non-accommodating arch distributes pressure abnormally across the foot.
Evaluation at Balance Foot & Ankle
Dr. Biernacki’s cavus foot evaluation includes: Coleman block test (determines whether hindfoot varus is flexible or fixed — a critical distinction for surgical planning); weight-bearing foot and ankle X-rays with Meary’s angle and calcaneal pitch measurement; full lower extremity neurological examination; EMG and nerve conduction studies; and MRI of the spine when intraspinal pathology is suspected. Family history is explored — CMT is hereditary and a positive family history significantly increases diagnostic probability. Neurology referral is coordinated when a hereditary neuropathy is suspected.
Conservative Treatment
Mild cavus foot with flexible deformity and minimal neurological involvement is managed conservatively. Custom orthotics with lateral forefoot posting and heel cushioning redistribute pressure away from the overloaded lateral column and first metatarsal. Ankle-foot orthoses (AFOs) — particularly carbon fiber designs — address associated peroneal weakness and ankle instability. Physical therapy focuses on peroneal strengthening, balance retraining, and proprioceptive training to reduce fall and sprain risk. Lateral ankle bracing is prescribed for patients with documented ankle instability.
Surgical Reconstruction for Cavus Foot
Progressive or severe cavus foot — particularly with fixed hindfoot varus, severe claw toes, or refractory ankle instability — requires surgical reconstruction. Dr. Biernacki’s approach is tailored to the specific deformity components: plantar fascia release addresses plantarflexion deformity of the first ray; first metatarsal dorsiflexion osteotomy elevates the dropped first metatarsal head; calcaneal lateral closing wedge osteotomy corrects hindfoot varus; claw toe correction addresses the toe deformities; and peroneus longus-to-brevis tendon transfer improves hindfoot eversion. Lateral ligament reconstruction (Brostrom) addresses chronic ankle instability in the same setting. The reconstructive sequence is precisely planned to address each deformity component in the correct order.

- CMT has no cure — treatment is symptomatic and deformity-correcting only
- Multiple surgical procedures may be staged if deformity is severe
Dr. Tom Biernacki’s Recommendation
Cavus foot is a condition that gets missed for years — patients have repeated lateral ankle sprains and stress fractures and no one connects the dots to the high arch. The first thing I do with any cavus foot is get EMG/nerve conduction studies and evaluate for Charcot-Marie-Tooth disease, because it changes the prognosis and family screening implications. The surgical reconstruction for cavus is complex and gratifying — we can take someone who was spraining their ankle every few months and give them a stable, functional foot for the long term.

Frequently Asked Questions
What causes high arches?
High arches can be idiopathic (no identifiable cause), hereditary (often related to Charcot-Marie-Tooth disease or other neuropathies), or acquired from neurological conditions including spinal cord tumors, cerebral palsy, and spina bifida. Any progressive cavus deformity should be evaluated with EMG and neurological consultation to rule out a treatable neurological cause.
Is cavus foot painful?
Not always — many patients with high arches have no symptoms, particularly in mild cases. When symptomatic, cavus foot causes lateral foot pain from overloading, repeated ankle sprains, stress fractures (especially fifth metatarsal), plantar fasciitis, metatarsalgia, and claw toe pain. The rigidity of the high arch distributes pressure abnormally.
Can orthotics fix high arches?
Custom orthotics can redistribute pressure and reduce symptoms significantly in mild to moderate cavus foot — but they don’t correct the underlying structural deformity. For progressive or severe cavus, orthotics are a temporizing measure while surgical reconstruction planning occurs.
What is Charcot-Marie-Tooth disease and how does it relate to foot problems?
Charcot-Marie-Tooth (CMT) is the most common hereditary neuropathy, affecting 1 in 2,500 people. It progressively weakens the peroneal and intrinsic foot muscles, causing the characteristic CMT foot — cavus deformity, claw toes, peroneal weakness, and ankle instability. Dr. Biernacki coordinates with neurology for CMT diagnosis, genetic counseling, and long-term management.

When should I see a podiatrist?
If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).
What does treatment cost?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.
How quickly can I get an appointment?
Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.
What is Foot pain?
Foot pain is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of foot pain include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of foot pain respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from foot pain varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
