A cavus foot is defined by an abnormally high longitudinal arch that places excessive pressure on the heel and forefoot. Unlike a flexible flatfoot, cavus feet are usually rigid; left unaddressed they can trigger ankle sprains, metatarsalgia, stress fractures, and progressive claw-toe deformities. Our board-certified podiatrists deliver gait-analysis-driven orthotic care and, when needed, staged reconstructive surgery to rebalance load and restore stability.
| Neurologic / Genetic | Structural & Biomechanical | Mechanical / Lifestyle |
|---|---|---|
| Charcot-Marie-Tooth disease (CMT) – most common neurologic cause | Forefoot-driven cavus (plantarflexed first ray) | Repetitive high-impact sports on rigid surfaces |
| Spasticity after stroke, cerebral palsy, or spinal tumor | Hind-foot varus with rigid subtalar joint | Chronic high-heel or tight-cleat use exaggerating arch |
| Familial “hereditary cavus” without overt neurologic deficit | Short or weak peroneus brevis vs. overpowering tibialis posterior | Previous midfoot trauma with malunion |
Muscle-imbalance (inversion > eversion) plantar-flexes the first ray, inverts the heel, and locks the subtalar joint—producing a rigid, high-arched foot.
| Conservative (All Stages) | Reconstructive Procedures (Stage-Matched) |
|---|---|
| Custom orthotics with lateral forefoot posting to off-load first ray | Dorsiflexion 1st-ray osteotomy (DFO) for flexible forefoot-driven cavus |
| Lateral-flare shoe soles & high-cushion midsoles | Calcaneal lateral-slide or closing-wedge osteotomy to correct hind-foot varus |
| Peroneal-strength & gastroc-stretch program | Plantar fascia release & Steindler stripping to address arch rigidity |
| Ankle-brace for recurrent sprain | Claw-toe correction (PIP arthrodesis or tendon transfer) |
| NSAIDs / activity modification for peroneal tendonitis | Midfoot dorsal wedge osteotomy for rigid midfoot cavus |
| — | Tendon transfers (posterior tibial → dorsum; peroneus longus → brevis) to rebalance muscle forces |
Prospective series show ≥ 80 % pain relief and improved balance after combined lateralizing calcaneal osteotomy + first-ray dorsiflexion osteotomy in adult rigid cavus.
They won’t change bone shape, but they redistribute pressure, add lateral stability, and reduce pain—often enough to avoid or postpone surgery.
No. Up to half are idiopathic or familial. Nonetheless, we screen because unrecognized neurologic causes require different long-term planning.
Typical protocol: 6 weeks non-weight-bearing cast, 6 weeks boot with partial load, then physical therapy. Return to low-impact sport ~4 months; full activity 6–8 months.
Persistent ankle rolls, forefoot pain, or shoe-fit problems from a high-arched foot deserve expert attention. Book an evaluation with North Texas Podiatry Associates to map your cavus type and choose the right blend of support, therapy, or surgical correction.
