Quick answer: Arch Types is a common foot/ankle topic that affects many patients. The 2026 evidence-based approach combines proper diagnosis, conservative-first treatment, and escalation only when needed. We treat this regularly at our Howell and Bloomfield Township practices. Call (810) 206-1402.
The most important clinical decision with Arch Types isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
Arch Types: Quick Answer
The 3 main foot arch types are: high arches (cavus foot — about 20% of the population), normal arches (about 60%), and low/flat arches (pes planus — about 20%). Each type has different biomechanical implications: high arches concentrate weight on the heel and ball of foot (more lateral foot pain, ankle sprains, supination); normal arches absorb shock evenly (least foot pathology); flat arches overpronate and stress the medial structures (more plantar fasciitis, posterior tibial tendinopathy, knee/hip pain). The wet-foot test is the simplest at-home identification: wet your feet, step on cardboard, examine the print. Treatment varies by type: high arches need cushioned neutral shoes + lateral wedge orthotics; flat arches need motion-control shoes + medial post orthotics; normal arches have the most flexibility in shoe choice.
What Determines Your Arch Type?
Your foot arch type is determined by the structural relationship between the bones of the midfoot (the talus, navicular, cuboid, three cuneiforms) and the soft-tissue structures that support them (plantar fascia, posterior tibial tendon, peroneal tendons, intrinsic muscles).
Genetic factors: Arch type is largely inherited — if your parents have flat feet or high arches, you have a 60-70% chance of having the same type. Specific genes related to arch development have been identified.
Acquired factors: Pregnancy (relaxin loosens ligaments, can cause arch flattening); aging (gradual posterior tibial tendon weakening); weight gain; chronic high-impact activity; specific neurologic conditions (Charcot-Marie-Tooth disease causes high-arched cavus foot).
Functional vs structural: Some flat-footed people have flexible flatfoot (the arch appears when sitting but flattens when standing) — this is functional and treatable. Others have rigid flatfoot (no arch even when not weight-bearing) — usually due to long-standing collapse or congenital tarsal coalition.
The 3 Arch Types Explained
1. Normal Arches (~60% of population): Visible curve along the inside of the foot when standing. The wet footprint shows a clear band on the lateral side connecting heel to forefoot, with a curved cutout on the medial (inner) side. Biomechanically optimal — even shock absorption, normal pronation. Generally lower risk of foot conditions.
2. High Arches / Cavus Foot (~20%): Pronounced upward curve. The wet footprint shows only a thin connection between heel and forefoot prints (or no connection at all in severe cavus). Bony, rigid feet that don’t pronate enough to absorb shock — leading to lateral foot loading and ankle instability.
3. Low Arches / Flat Feet / Pes Planus (~20%): Visible inward roll of the ankle when standing. The wet footprint shows a broad solid print with no medial cutout. Excessive pronation flattens the arch and stresses the medial structures (posterior tibial tendon, plantar fascia).
How to Test Your Arch Type at Home
The Wet Foot Test (most popular): Wet both feet thoroughly. Step on a piece of cardboard or a paper bag. Step off and examine the print.
— High arch: only thin connection (or none) between heel and forefoot prints.
— Normal arch: clear curve along the inside; band along the outside connecting heel and forefoot.
— Flat arch: broad solid print; no curve along the inside; entire foot bottom visible in the print.
The Pencil Test: Slide a pencil under the inside of your foot when standing. If it doesn’t fit at all = flat arch. If it fits partially = normal arch. If it fits completely with significant gap = high arch.
The Shoe Wear Pattern: Look at your old running shoes. Wear concentrated on the lateral (outside) edge = supinator (high arch). Wear concentrated on the medial (inside) edge = overpronator (flat arch). Even wear = normal arch.
The Single-Leg Heel Raise: Stand on one foot. Rise onto your toes. Watch your heel from behind. Heel inverts (turns inward) = normal/high arch with proper posterior tibial function. Heel doesn’t invert = flat arch with possible posterior tibial dysfunction.
Conditions Associated With Each Arch Type
High arches (cavus foot):
— Ankle sprains (lateral ligament injuries) — supinator stance increases inversion risk.
— Peroneal tendinopathy and tendon tears.
— 5th metatarsal stress fractures (Jones fractures).
— Lateral foot pain (cuboid syndrome, sinus tarsi).
— IT band syndrome and lateral knee pain.
— Hammertoes (claw toes especially).
Flat arches (pes planus):
— Plantar fasciitis (#1 — affects 30-50% of flat-footed people at some point).
— Posterior tibial tendinopathy and PTTD progression to flatfoot.
— Bunions (overpronation accelerates 1st MTP drift).
— Hallux rigidus (big toe arthritis).
— Medial knee pain and IT band syndrome.
— Lower back pain.
Normal arches:
— Lowest risk overall.
— Still susceptible to common conditions (turf toe, fractures, corns) but not at biomechanically elevated risk.
Treatment by Arch Type
High Arches:
— Shoes: cushioned neutral (HOKA Bondi, Brooks Glycerin, Saucony Triumph). AVOID stability shoes — they make supination worse.
— Orthotics: lateral wedge to redirect weight medially; cushioned topcover for shock absorption; metatarsal pad for forefoot loading.
— Strengthening: ankle stability work to compensate for poor shock absorption; calf and intrinsic foot muscle strengthening.
— Best shoes for supination guide.
Flat Arches:
— Shoes: motion control or stability (Brooks Adrenaline GTS, ASICS Kayano, Saucony Guide). Avoid neutral cushion shoes alone.
— Orthotics: medial heel post; rigid arch support; possibly heel cup for posterior tibial unloading.
— Strengthening: posterior tibial eccentric strengthening; intrinsic foot strengthening (short foot exercise); calf stretching.
— Best orthotics for flat feet.
Normal Arches:
— Shoes: any neutral category works; choose based on cushion preference and activity.
— Orthotics: usually not needed unless specific condition develops.
— Strengthening: general foot exercises for prevention.
When Custom Orthotics Are Worth It
Custom orthotics make sense when: OTC orthotics haven’t resolved your symptoms after 6-8 weeks; you have asymmetric pronation; you have multiple foot conditions; you stand or walk many hours daily; you have diabetes (Medicare covers diabetic shoes annually); you’re a serious athlete.
Custom orthotic features: Cast or 3D-scanned to your specific foot architecture; adjustable as your needs change; correct material rigidity for your activity; incorporates specific posting, wedging, and accommodative features for your conditions.
Cost: $300-600 per pair typical. Sometimes covered by FSA/HSA. Some insurance plans cover. Last 3-5 years (vs 6-12 months for OTC).
OTC orthotics make sense when: First-line treatment for mild conditions; budget-conscious; trying orthotic therapy before committing to custom. Top picks: PowerStep Pinnacle, PowerStep Pinnacle GREEN, Vionic Active. $30-65.
When to See a Podiatrist
Same-week appointment if: foot pain related to arch type; recurring injuries (plantar fasciitis, ankle sprains); you suspect adult-acquired flatfoot deformity (PTTD); want custom orthotic evaluation; want gait analysis; you have asymmetric arches (one foot worse than other). At Balance Foot & Ankle we offer comprehensive biomechanical evaluation including video gait analysis and 3D foot scanning for custom orthotics.
Frequently Asked Questions About Arch Types
How do I know what arch type I have?
Use the wet foot test: wet feet, step on cardboard, examine print. High: thin connection. Normal: clear curve. Flat: broad solid print. Confirm with shoe wear pattern (lateral wear = supinator/high arch; medial wear = overpronator/flat).
Is having flat feet bad?
Not inherently — about 20% of people have flat feet. Risk increases for plantar fasciitis, posterior tibial tendinopathy, bunions, and knee pain. Proper shoes + orthotics largely mitigate these risks.
Can I change my arch type?
Structural arch type is largely fixed (genetic). Functional flatfoot can be supported with strengthening + orthotics. Surgery rarely changes arch type but can correct severe deformities.
What’s the best shoe for high arches?
Cushioned neutral shoes: HOKA Bondi 9, Brooks Glycerin 22, Saucony Triumph 22, ASICS Gel-Nimbus 26. AVOID stability/motion-control shoes which make supination worse.
What’s the best shoe for flat feet?
Motion-control or stability: Brooks Adrenaline GTS, ASICS Kayano, Saucony Guide, New Balance 860. Add custom orthotic with medial post for moderate-severe cases.
Do flat feet always cause problems?
No — many flat-footed people are pain-free with no foot conditions. Problems occur when there’s biomechanical compensation that stresses other structures (knee, back). Asymptomatic flat feet need no treatment.
Can orthotics raise my arch?
Orthotics support the arch but don’t permanently raise it. The arch lifts when wearing the orthotic and falls back when not wearing. Long-term wear can strengthen supporting muscles indirectly.

Book Your AppointmentRecommended Insoles for Your Arch Type
The right insole for your arch type can dramatically reduce pain, improve gait efficiency, and prevent injuries. For low arches (flat feet), a firm, structured insole with a deep heel cup and medial arch post limits excessive pronation. For high arches, a cushioned insole with a flexible arch and forefoot padding absorbs the shock that a rigid high-arched foot cannot distribute normally. For neutral arches, a semi-rigid insole provides moderate support without overcorrecting natural mechanics. In our clinic, we assess both static arch height and dynamic foot function — because a foot can appear to have a normal arch at rest but pronate excessively during walking.
