Understanding Pes Cavus (High Arch Foot)
Pes cavus is defined by an abnormally elevated medial longitudinal arch, producing a rigid foot with reduced contact area and altered load distribution. Unlike flatfoot (which loads the medial column excessively), pes cavus concentrates forces on the heel and forefoot — particularly the lateral column — with relative unloading of the midarch. The result is a foot that lacks the shock absorption and adaptability of a normal arch, predisposing to a characteristic cluster of conditions: lateral ankle instability, lateral metatarsal stress fractures, peroneal tendinopathy, plantar fasciitis, and progressive claw toe deformity.
The Critical Question: Is There a Neurological Cause?
50–65% of pes cavus is neurological in origin — the most common cause being Charcot-Marie-Tooth disease (CMT), a hereditary peripheral neuropathy that causes progressive intrinsic foot muscle weakness. Other neurological causes include Friedreich’s ataxia, spinal cord tethering, polio, spastic cerebral palsy, and stroke. The clinical red flag for neurological pes cavus is bilateral, progressive deformity — unilateral pes cavus is more likely to be idiopathic or post-traumatic. Dr. Biernacki performs detailed neurological screening at the first evaluation and refers for neurology evaluation when CMT or another neurological cause is suspected, because neurological progression dictates the treatment strategy.
Conservative Treatment for Pes Cavus
Conservative management is first-line for most pes cavus patients. Custom orthotics with lateral wedging (lateral forefoot and rearfoot posting) redistribute load from the lateral column to reduce stress fracture and peroneal tendon risk. A metatarsal pad or deep heel seat addresses forefoot and heel loading. Ankle bracing (semi-rigid lace-up brace) is beneficial for patients with lateral ankle instability from hindfoot varus — stabilizing the ankle during sports and uneven terrain. Footwear guidance: high-arch patients should avoid flexible minimalist shoes; cushioned neutral shoes with a wide toe box and accommodative platform are recommended. Physical therapy for Achilles and plantar fascia stretching, peroneal strengthening, and proprioception training.
Surgical Correction
Surgical correction is indicated for progressive, rigid pes cavus with significant functional limitation despite conservative care. Surgery is customized to the specific deformity components. Plantar fascia release (Steindler stripping) addresses the tight plantar structures driving the elevated arch. Dorsal closing wedge osteotomies of the metatarsals (modified Jones technique) depress elevated metatarsal heads. Calcaneal osteotomy (Dwyer lateral closing wedge) corrects hindfoot varus. Tendon transfers (peroneus longus-to-brevis transfer, tibialis posterior transfer) restore dynamic muscle balance in neurological pes cavus. Claw toe correction — often combined with foot reconstruction — addresses the inevitable toe deformities. The specific combination of procedures is planned based on deformity analysis with weight-bearing X-rays and clinical examination.
Dr. Tom's Product Recommendations
CURREX RunPro High Arch Insole
⭐ Highly Rated
High-arch profile dynamic insole specifically designed for pes cavus patients — provides cushioning and lateral wedging without over-supinating a high-arch foot.
Dr. Tom says: “”CURREX RunPro in the high-arch profile is one of the few OTC insoles I recommend specifically for pes cavus — most ‘high arch’ supports actually increase supination, but CURREX addresses this correctly with its profile-matched design.” — Dr. Biernacki”

✅ Pros / Benefits
- Neurological evaluation for bilateral progressive pes cavus identifies CMT and other treatable causes — changing both prognosis and surgical timing decisions.
- Custom lateral-wedge orthotics effectively redistribute pes cavus loading and reduce stress fracture and peroneal tendon injury risk.
- Combined foot reconstruction addressing multiple deformity components simultaneously (calcaneal osteotomy + tendon transfer + claw toe correction) delivers comprehensive correction.
❌ Cons / Risks
- Neurological pes cavus (CMT) is progressive — surgery provides correction but cannot stop underlying neurological progression; ongoing monitoring and repeat procedures may be needed.
- High arch foot reconstruction is complex multi-procedure surgery requiring expertise in deformity analysis and combined bony + soft tissue correction.
- Rigid pes cavus deformity is less correctable than flexible deformity — early evaluation and treatment before rigidity develops is strongly recommended.
Dr. Tom Biernacki’s Recommendation
High arch foot is consistently underdiagnosed and undertreated. Patients are told ‘you have high arches, that’s just how your feet are’ without being evaluated for neurological causes or given appropriate orthotic support. When I see bilateral high arches with progressive claw toes in a younger patient, I’m immediately thinking CMT — that’s a diagnosis that changes the entire management approach. Every pes cavus patient gets a proper neurological screen at their first visit.

Frequently Asked Questions
Are high arches inherited?
Yes — idiopathic pes cavus has a hereditary component, and many neurological causes (particularly CMT) are directly inherited in autosomal dominant or recessive patterns. If a parent has high arches with progressive claw toes, their children should be evaluated for CMT. Genetic testing for common CMT mutations is available through neurology.
Why do people with high arches sprain their ankles more often?
Hindfoot varus (the heel tilts inward) in pes cavus positions the ankle in an inverted posture at heel strike, reducing the mechanical barrier to inversion sprains. The peroneal tendons also work at a mechanical disadvantage in varus alignment, reducing their ability to arrest inversion moments. Custom lateral wedge orthotics and ankle bracing significantly reduce sprain risk.
What kind of shoes are best for high arches?
High-arch patients need cushioned shoes with a neutral-to-slightly-curved last (avoiding straight, medially posted shoes), a wide forefoot, and a low drop (0–4mm). Motion control and stability shoes with heavy medial posting worsen supination in pes cavus patients. Dr. Biernacki provides specific footwear guidance tailored to the patient’s degree of cavus deformity.
Can high arch foot cause plantar fasciitis?
Yes — the tight plantar fascia in pes cavus is under constant stretch from the elevated arch, making plantar fasciitis common. However, pes cavus plantar fasciitis responds differently to treatment than standard overpronation-related fasciitis — lateral wedge orthotics and plantar fascia stretching are more appropriate than the standard anti-pronation orthotics used for flatfoot.

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.
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 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.

What causes pes cavus (high arch foot) and why does it cause pain?
Pes cavus is a foot deformity characterized by an abnormally high medial longitudinal arch -- the opposite of flatfoot (pes planus) -- caused by muscle imbalance between extrinsic and intrinsic foot muscles; it is clinically important because a high-arched, rigid foot has poor shock absorption, high plantar pressures, and a tendency toward lateral ankle instability, all of which drive a characteristic pattern of foot and ankle pain. The normal arch and how cavus develops: the medial longitudinal arch is maintained by the interplay of intrinsic foot muscles (lumbricales, interossei, flexor digitorum brevis) and extrinsic muscles (peroneus longus, tibialis posterior, flexor hallucis longus); when this balance is disrupted by neurological disease affecting motor neurons, the stronger muscles overpower the weaker ones, pulling the foot into the cavus deformity; in approximately 70% of cavus feet, an underlying neurological cause is identified: Charcot-Marie-Tooth disease (hereditary motor and sensory neuropathy): the most common neurological cause; progressive peripheral neuropathy that affects the intrinsic foot muscles and the peroneus brevis earlier than the opposing muscles; the peroneus longus (plantarflexes the first metatarsal) and the tibialis posterior remain stronger; the imbalance elevates the first metatarsal (plantarflexion), creating the forefoot-driven cavus; Friedreich's ataxia, spinal dysraphism (spina bifida), poliomyelitis, cerebral palsy, and Charcot-Marie-Tooth are the most common neurological causes; idiopathic cavus: no identifiable neurological cause; may represent the extreme end of the normal arch height distribution; The cavus foot biomechanics and pain generators: the high arch creates a rigid, non-deformable foot structure; shock absorption during heel strike is dramatically reduced compared to a flexible flat foot; the high arch concentrates plantar pressure under the heel and the metatarsal heads (rather than distributing it across the midfoot); specific pain patterns: lateral column overload (fifth metatarsal stress fractures, peroneal tendinopathy, lateral ankle sprains from the supinated hindfoot position that predisposes to inversion); metatarsalgia (high pressure under the metatarsal heads from the cavus forefoot position); plantar fasciitis (the tight plantar fascia of the cavus foot); claw toe deformities (from intrinsic muscle weakness); ankle instability (the supinated hindfoot position stretches the lateral ankle ligaments).
How is pes cavus (high arch) treated?
Pes cavus treatment is guided by the severity of the deformity, the presence of an underlying neurological cause, whether the deformity is flexible or rigid, and which specific pain generators are dominant -- conservative management with orthotics is the first-line approach; surgery addresses the structural deformity in cases with progressive pain, instability, or failed conservative management. Conservative treatment: custom orthotics (the mainstay of conservative management): the design goal is to redistribute the abnormally concentrated plantar pressure across a larger surface area; a lateral heel wedge shifts weight-bearing medially, reducing lateral column overload; a metatarsal pad or bar reduces forefoot peak pressures under the metatarsal heads; a full-length total contact design accommodates the entire cavus arch; the orthotic must fit precisely -- a cavus foot often cannot accommodate standard off-the-shelf insoles; extra-depth footwear: a shoe with a deep, wide toe box to accommodate the claw toes; rocker-bottom sole reduces the demands on the forefoot during push-off; ankle bracing: a lace-up ankle brace or custom ankle-foot orthosis (AFO) for patients with significant lateral ankle instability from the supinated hindfoot; physical therapy: stretching of the plantar fascia and Achilles tendon; peroneal strengthening for lateral ankle instability; proprioceptive training; Surgical treatment (for flexible deformity failing conservative care or progressive rigid deformity): the principle of cavus foot surgery: correct the deformity from the apex of the deformity outward; the apex of most cavus feet is at the first TMT joint (the first metatarsal is plantarflexed); Soft tissue procedures (for flexible deformity): plantar fascia release: the tight plantar fascia maintains the elevated arch; releasing it is the first step in flexible cavus correction; peroneus longus to brevis transfer: transfers the first metatarsal plantarflexor force (peroneus longus) to a foot evertor (peroneus brevis); reduces the deforming force on the first metatarsal; posterior tibial tendon lengthening: for equinus component; Bony procedures (for rigid or residual deformity after soft tissue correction): first metatarsal dorsiflexion osteotomy: elevates the plantarflexed first metatarsal; reduces forefoot-driven cavus; calcaneal osteotomy (Dwyer): a lateral closing wedge osteotomy of the calcaneus corrects the hindfoot varus that is frequently part of cavus deformity; triple arthrodesis: for rigid severe cavus deformity with arthrosis; fuses the subtalar, talonavicular, and calcaneocuboid joints in a corrected position; highly reliable for severe deformity; Claw toe correction: concurrent correction of claw toe deformities prevents recurrence and corrects the intrinsic muscle imbalance component.
