The most important clinical decision with High Arch Foot Pes Cavus Treatment Michigan Podiatrist isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
Understanding Pes Cavus: The High Arch Foot
Pes cavus — commonly called high arch foot or cavus foot — is characterized by an elevated medial longitudinal arch that fails to flatten adequately with weight-bearing. Unlike flat feet, the high arch transmits excessive load to the heel and the metatarsal heads (the ball of the foot), generating characteristic painful calluses at these sites. The supinated (under-rolled) gait pattern associated with cavus foot places the lateral border under extraordinary stress, creating susceptibility to lateral ankle sprains, chronic ankle instability, stress fractures of the fifth metatarsal, and peroneal tendon pathology.
Neurological Evaluation Is Essential
A critical step that distinguishes Dr. Biernacki’s evaluation from routine foot care is mandatory neurological screening in all pes cavus patients. Up to 60–70% of cavus foot deformity has an identifiable neurological cause — most commonly Charcot-Marie-Tooth disease (hereditary motor and sensory neuropathy), but also Friedreich’s ataxia, poliomyelitis sequelae, spinal cord lesions, and cerebral palsy. Progressive cavus deformity, bilateral involvement, and family history strongly suggest a neurological etiology. Referral to neurology for nerve conduction studies and genetic evaluation is arranged when indicated. Identifying an underlying condition does not change foot treatment but alerts the care team to systemic implications and family member risk.
Conservative Treatment
Custom foot orthotics for cavus feet differ fundamentally from flat foot orthotics — they require lateral wedging to support the lateral column, metatarsal padding to disperse plantar pressure from the metatarsal heads, and deep heel cups to support the heel pad. Lateral ankle bracing — Arizona or custom AFO — provides the stability the chronic supination pattern makes necessary. Appropriate footwear with a wide toe box, cushioned midsole, and flexible forefoot accommodates the rigid cavus foot without creating additional pressure points. Physical therapy for peroneal and intrinsic foot muscle strengthening addresses the dynamic component of instability. Callus management with regular debridement prevents painful progression to skin breakdown.
Surgical Treatment for Rigid or Progressive Cavus
Patients with rigid cavus deformity, progressive neurological disease, or those failing comprehensive conservative care are candidates for surgical correction. Surgical procedures are tailored to the deformity components: plantar fascia release addresses the plantar contracture maintaining the high arch; metatarsal osteotomy lowers prominent metatarsal heads; calcaneal osteotomy addresses hindfoot varus; peroneus longus to brevis transfer corrects dynamic plantarflexion of the first ray; and ankle ligament reconstruction addresses the resulting instability. Complex cavus reconstruction may combine multiple procedures in a single operative session for comprehensive correction.
Dr. Tom's Product Recommendations
Powerstep Pinnacle Plus Ball-of-Foot Cushion Insoles
⭐ Highly Rated
Semi-rigid arch support with integrated metatarsal pad — designed to redistribute pressure from painful metatarsal heads, making it ideal for high-arch patients with ball-of-foot calluses and metatarsalgia.
Dr. Tom says: “Metatarsal padding is essential for cavus foot relief — this insole provides it in one product.”

HOKA ONE ONE Bondi 8 Running Shoe
⭐ Highly Rated
Maximum-cushion neutral running shoe with oversized midsole — an excellent choice for high-arch patients who need maximum impact absorption without a motion-control arch support that would worsen cavus mechanics.
Dr. Tom says: “Maximum cushioning neutralizes the high-impact landing pattern of cavus feet.”

✅ Pros / Benefits
- Neurological evaluation and referral coordination included in cavus assessment
- Custom lateral-wedge orthotics designed for cavus mechanics
- Comprehensive surgical correction planning for rigid deformity
- Peroneal tendon and ankle instability co-management
❌ Cons / Risks
- Neurologically-driven cavus deformity is progressive — conservative care manages symptoms but does not stop underlying disease
- Surgical correction of rigid cavus is technically complex with significant recovery
Dr. Tom Biernacki’s Recommendation
High arch feet are too often overlooked until serious problems develop. Stress fractures, chronic ankle instability, and progressive deformity can all result from untreated cavus foot. Just as importantly, some cases of high arch feet are the first sign of a neurological condition affecting the whole family. If you have high arches and foot pain, come in for a proper evaluation.

Frequently Asked Questions
Is a high arch worse than flat feet?
Both deformities can cause significant problems, but they affect different structures and require very different treatments. High arch feet typically cause more ankle instability and metatarsal stress injuries, while flat feet are more commonly associated with arch tendon problems. Neither is inherently ‘worse’ — the key is getting the right diagnosis and treatment for each.
Can high arch feet be corrected without surgery?
Most cavus foot patients are successfully managed without surgery using custom orthotics, appropriate footwear, physical therapy, and lateral ankle bracing. Surgery is reserved for rigid deformity, progressive neurological disease, or patients failing thorough conservative care.
Does high arch foot run in families?
Often yes — Charcot-Marie-Tooth disease, the most common neurological cause of pes cavus, is hereditary. Family members of patients with cavus foot should be evaluated, particularly if bilateral or progressive foot deformity is present.

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.
