Children’s Foot Care: What’s Normal, What Isn’t
Parents bring children to podiatrists with more concern than almost any other specialist — and appropriately so. Foot development affects gait, posture, and long-term musculoskeletal health. The challenge is that many common-looking concerns are completely normal variants that resolve spontaneously, while a few apparently mild problems represent conditions that will worsen without intervention.
Dr. Tom Biernacki provides pediatric foot evaluations with a clear framework: what is the child’s age, what developmental stage is expected, is this a normal variant or a true pathology, is the child having pain or functional limitation, and what is the natural history if we watch and wait? This framework prevents both under-treatment (missing a tarsal coalition or early Charcot foot in a diabetic teenager) and over-treatment (prescribing orthotics for every toddler with flat feet).
Common Pediatric Foot Conditions by Age Group
Infants and Toddlers (Ages 0–3)
Metatarsus adductus: Forefoot adduction (C-shaped foot) is the most common foot deformity present at birth, affecting 1 in 1000 live births. Flexible metatarsus adductus (forefoot passively correctable past neutral) — the majority of cases — resolves spontaneously by age 2–3. Rigid metatarsus adductus (forefoot fixed in adduction) requires serial casting starting before 6 months for optimal results. Parents frequently confuse metatarsus adductus with in-toeing — the deformity is in the forefoot, not rotational.
Calcaneovalgus: A flexible dorsiflexed foot that appears to fold up against the shin — common at birth from in-utero positioning, resolves spontaneously in 2–6 months with gentle range-of-motion exercises.
Clubfoot (CTEV): True clubfoot — calcaneus, varus, equinus, adductus — is identified at birth and treated with Ponseti serial casting starting in the first week of life. Dr. Biernacki coordinates with pediatric orthopedics for Ponseti casting and the subsequent Achilles tenotomy and bracing protocol.
School-Age Children (Ages 4–12)
Sever’s Disease (Calcaneal Apophysitis): The most common cause of heel pain in children ages 8–14, Sever’s disease is an overuse traction apophysitis at the calcaneal growth plate — where the Achilles tendon inserts before the apophysis fuses between ages 14–16. Pain is reproduced by medial-lateral calcaneal squeeze. X-ray shows sclerosis and fragmentation of the apophysis — normal variant finding that doesn’t confirm the diagnosis clinically. Treatment: relative activity modification (not complete rest), heel lifts, Achilles stretching, and calf strengthening. Resolves completely with skeletal maturity — this is important reassurance for worried parents.
Tarsal Coalition: Bony or fibrocartilaginous fusion between tarsal bones — most commonly calcaneonavicular (diagnosed on oblique foot X-ray) and talocalcaneal middle facet (CT scan required). Presents in school age with recurrent ankle “sprains,” peroneal spasm, and rigid flat foot. Missed tarsal coalition leads to years of inappropriate sprain treatment. Resection produces excellent outcomes when performed before secondary arthritic changes develop.
Pediatric Flatfoot: Flexible flatfoot is present in 20–30% of children and the majority resolve by age 6–8. Persistent flexible flatfoot with arch pain, leg fatigue, or activity limitation warrants evaluation. Custom orthotics for symptomatic flexible flatfoot in children improve comfort and function. Subtalar arthroereisis (sinus tarsi implant) is an appropriate surgical option for children ages 8–12 with symptomatic flexible flatfoot failing 6+ months of orthotic management — reversible, minimally invasive, produces 70–85% deformity correction.
Adolescents (Ages 12–18)
Osgood-Schlatter analog at the foot — Iselin’s disease: Apophysitis of the 5th metatarsal base in adolescents — similar pathomechanism to Sever’s at the heel but at the peroneus brevis insertion. Lateral foot pain at the 5th metatarsal base in a growing athlete must be distinguished from an acute avulsion fracture (Dancer’s fracture) and a Jones fracture — all three occur at different zones of the proximal 5th metatarsal and have radically different management.
Juvenile hallux valgus: Bunion deformity in adolescents is often hypermobile and driven by hereditary joint laxity — different biomechanics from adult bunion. Surgery before skeletal maturity carries higher recurrence risk; conservative management with orthotics and appropriate footwear is strongly preferred until growth plates close.
Stress fractures in adolescent athletes: Second metatarsal stress fractures in ballet dancers and distance runners, navicular stress fractures in soccer players, calcaneal stress fractures in cross-country runners — all require prompt diagnosis with MRI or bone scan when clinical suspicion is high and plain X-rays are negative.
Ingrown Toenails in Children
Pediatric ingrown toenails are one of the most common nail conditions treated in a podiatry practice. Poor nail cutting technique (rounding the corners rather than cutting straight across), tight footwear, and hereditary nail curvature all contribute. Most pediatric ingrown toenails can be treated with partial nail plate avulsion under digital block anesthesia — a quick, well-tolerated office procedure. For recurrent ingrown toenails from hereditary overcurved nail plate, permanent partial matrixectomy with phenol prevents regrowth of the offending nail border permanently. The procedure is appropriate for children as young as 10–12 years who can cooperate with the office procedure.
Dr. Tom's Product Recommendations
Tuli’s Heavy Duty Heel Cup
⭐ Highly Rated
The Tuli’s Heavy Duty Heel Cup is the primary product recommendation for Sever’s disease — providing targeted calcaneal cushioning that reduces impact on the vulnerable growth plate. Fits in athletic shoes and cleats. Worn bilaterally even when only one heel is symptomatic (bilateral involvement is the rule).
Dr. Tom says: “Our son had terrible heel pain at soccer practice. Dr. Biernacki diagnosed Sever’s disease and recommended these. Back to full practice within 10 days.”
Sever’s disease, calcaneal apophysitis, youth athletics
Should be replaced when compression is visibly reduced — typically every few months in active children

New Balance 990v6 Kids – Stability Athletic Shoe
⭐ Highly Rated
The NB 990v6 Kids provides genuine medial stability in a properly engineered children’s shoe — not the fashion sneaker with a supportive-looking outsole that many children wear. ENCAP midsole technology and wide widths support children with flexible flatfoot, Sever’s disease, and growing foot biomechanics.
Dr. Tom says: “Dr. Biernacki told us to stop buying fashion sneakers and get our daughter into the 990v6. Her arch pain from flatfoot went away within two weeks of switching shoes.”

Profoot Pediatric Orthotic Insoles
⭐ Highly Rated
Profoot pediatric orthotics are sized specifically for children’s feet — providing arch support and heel cupping in growing shoe sizes that adult orthotics cannot properly address. A reasonable OTC starting point for symptomatic pediatric flatfoot while custom orthotics are being arranged.
Dr. Tom says: “Our pediatrician kept saying our son’s flat feet were normal. Dr. Biernacki evaluated them properly and found they were causing his leg pain. These insoles helped while his custom orthotics were being made.”

✅ Pros / Benefits
- Age-specific developmental framework — not treating normal variants unnecessarily
- Tarsal coalition detection with oblique X-rays and CT when clinical findings warrant
- Sever’s disease diagnosis and management with appropriate activity guidance (not ‘complete rest’)
- Pediatric ingrown toenail treatment with permanent correction option
- Subtalar arthroereisis for appropriate pediatric flatfoot surgical candidates
❌ Cons / Risks
- Many pediatric flat feet and in-toeing presentations do NOT require treatment — parents expecting orthotics for every flat-footed child may be reassured instead
- Clubfoot management is coordinated with pediatric orthopedics for the serial casting phase
- Juvenile hallux valgus surgery is generally deferred until skeletal maturity — conservative management is emphasized
Dr. Tom Biernacki’s Recommendation
I see a lot of parents who are worried their child’s flat feet or in-toeing will cause problems for life. Most of the time, I’m able to reassure them that development is on track and orthotics aren’t needed. But occasionally I see the child who was reassured by three previous providers and has a tarsal coalition that nobody scanned, or a Sever’s disease that’s been treated as a sprain for six months. Getting the diagnosis right early matters enormously in kids — their bodies respond faster than adults, and properly timed intervention avoids years of unnecessary pain.

Frequently Asked Questions
At what age do flat feet in children need treatment?
Most children’s flat feet do not need treatment at any age. If a child under 6 has flat feet without pain or functional limitation, watchful waiting is appropriate — the majority develop normal arches by age 6–8. If a child over 6 has flat feet with persistent arch pain, leg fatigue, or avoidance of physical activity, evaluation and possibly custom orthotics are indicated. Any child at any age with a rigid flat foot (no arch formation on tip-toe) needs prompt evaluation for tarsal coalition.
My child’s heels hurt during sports — is this serious?
Heel pain in a growing athlete between ages 8–14 is Sever’s disease (calcaneal apophysitis) until proven otherwise — and Sever’s is not serious. It is painful but completely self-limiting, resolves when the growth plate fuses (ages 14–16), and responds well to heel cushioning and Achilles stretching. It does not cause long-term damage. However, heel pain in a child under 8 or over 15, or heel pain that is constant rather than activity-related, or heel pain with significant night pain warrants evaluation to rule out other causes.
Does my in-toeing child need treatment?
In-toeing (pigeon-toed gait) in children has three primary causes: metatarsus adductus (forefoot — typically resolves by age 2–3), internal tibial torsion (lower leg — typically corrects by age 8), and femoral anteversion (hip — typically corrects by age 10–12). The vast majority of in-toeing resolves spontaneously. Special shoes and twisting cables (Denis Browne bars) have no evidence for treating in-toeing after infancy and are no longer recommended. Evaluation is appropriate if in-toeing is progressive, asymmetric, or still present after age 12.
How is a tarsal coalition diagnosed?
Tarsal coalition is often underdiagnosed because standard AP and lateral foot X-rays may be normal — the calcaneonavicular coalition is best seen on the 45-degree oblique foot X-ray (producing the ‘anteater sign’ of bony bridging), while talocalcaneal coalition requires CT scan for diagnosis. Clinical findings that should prompt imaging: rigid flatfoot that doesn’t correct on tip-toe, recurrent ankle ‘sprains’ with fast recovery but slow return to sport, and pain or stiffness in the hindfoot in an adolescent athlete.

Frequently Asked Questions
When should I see a podiatrist?
See a podiatrist if: foot or ankle pain has lasted more than 2–4 weeks without improvement, you’re changing your gait to avoid pain, you have an open wound or sore that isn’t healing, you notice nail discoloration or thickening, you have diabetes and any foot concern, or pain is severe enough to wake you at night. Most foot conditions are easier and cheaper to treat early — what starts as a minor issue can become a surgical problem with months of delay.
What is the difference between a podiatrist and an orthopedic surgeon?
Podiatrists (DPM — Doctor of Podiatric Medicine) specialize exclusively in the foot, ankle, and lower leg. Orthopedic surgeons (MD/DO) have broader musculoskeletal training but variable foot/ankle subspecialization. For foot and ankle-specific problems, a podiatrist often has more focused training and experience. For injuries involving the leg above the ankle, complex pediatric cases, or multi-level reconstruction, orthopedic consultation may be appropriate. We frequently co-manage patients with orthopedic colleagues.
How do I know if my foot pain is serious?
Signs that warrant same-day or next-day evaluation: severe pain that appeared suddenly without clear cause, swelling, redness, and warmth that appeared suddenly (possible gout, infection, or Charcot fracture), an open wound that looks infected (redness spreading, pus, warmth), inability to bear weight, or any foot problem in a diabetic patient. Pain that’s been present for weeks and is stable is important but not an emergency — schedule within 1–2 weeks.
Can foot problems cause back and knee pain?
Yes — this is a kinetic chain effect. Abnormal foot mechanics (overpronation, supination, leg length discrepancy) cause compensatory changes in knee, hip, and lumbar alignment. Roughly 30% of patients presenting to our clinic with knee pain have a treatable foot-level biomechanical cause. Correcting foot mechanics with orthotics or appropriate footwear often provides significant knee and back relief. If you have chronic knee or back pain and haven’t had your foot mechanics evaluated, it’s worth a consult.
Are orthotics worth it?
For the right conditions, yes — custom orthotics are among the most cost-effective interventions in podiatry. They’re most effective for: plantar fasciitis, flat feet with secondary knee/back pain, leg length discrepancy, metatarsalgia, posterior tibial tendon dysfunction, and diabetic foot pressure management. Quality OTC orthotics ($35–60) resolve symptoms for 60% of patients with mild-to-moderate conditions. Custom orthotics are appropriate when OTC options have failed or when the biomechanical problem is complex. We cast custom orthotics in-office.
How do I choose the right running shoes?
Start with your foot type (flat, neutral, high arch) and running pattern (overpronator, neutral, supinator). Flat feet and overpronators do best in stability or motion-control shoes. Neutral feet do well in neutral-cushioned shoes. High arches need maximum cushioning with flexible soles. Always buy running shoes at the end of the day (foot swelling peaks then), get properly fitted by a specialist, and replace every 300–500 miles. If you’ve been injured repeatedly, a gait analysis can identify the mechanical flaw driving your injury pattern.
What is the difference between a sprain and a fracture?
A sprain is a ligament injury (the tissue connecting bones); a fracture is a break in the bone itself. Both can occur with the same trauma (ankle roll, fall). The old test — ‘if you can walk, it’s not broken’ — is wrong; many fractures are initially weight-bearable. Key differences: a fracture typically produces localized bone tenderness along the bone itself, while a sprain is tender over the ligament. X-ray is the standard to differentiate. High-grade sprains without proper treatment can be as disabling as fractures.
How do I prevent foot and ankle injuries?
The four most impactful prevention strategies: (1) Supportive, appropriately fitted footwear for your foot type and activity. (2) Gradual activity progression — the 10% rule (never increase weekly mileage or intensity by more than 10%). (3) Regular calf and ankle mobility work. (4) Strengthening the posterior tibial tendon, peroneals, and intrinsic foot muscles. Most overuse injuries are preventable; most acute injuries are not — but ankle sprain recurrence (60–70% without rehab) is prevented by balance and proprioception training.
