Quick Answer:
Quick Answer: Custom foot orthotics are prescription medical devices molded to your specific foot structure—different from over-the-counter insoles in design, materials, and function. Dr. Biernacki at Balance Foot & Ankle prescribes custom orthotics for Michigan patients when biomechanical correction is needed for plantar fasciitis, tendinopathy, deformity management, and diabetic foot protection.

Walk into any pharmacy and you’ll find a wall of insole options—gel pads, arch supports, heel cups, and full-length orthotics. Walk into a podiatrist’s office and you might be prescribed a custom orthotic—a medical device fabricated to the precise contours of your foot. The difference between these products matters enormously for some patients and not at all for others. Dr. Tom Biernacki at Balance Foot & Ankle helps Michigan patients make informed, evidence-based decisions about when custom orthotics are worth the investment and when an excellent OTC option is sufficient.
What Are Custom Orthotics?
Custom foot orthotics are prescription medical devices fabricated from a precise three-dimensional impression of the patient’s foot—either a foam box cast, plaster cast, or increasingly, a digital scan. The orthotic is then manufactured by a certified laboratory to the prescribing physician’s exact specifications: shell material (rigid, semi-rigid, flexible), accommodative modifications, forefoot posting, rearfoot posting, metatarsal pads, heel lifts, and other individualized elements. A properly prescribed and fabricated custom orthotic is categorically different from any mass-produced product.
What Are Store-Bought Insoles?
Over-the-counter insoles range from basic gel cushion pads to sophisticated semi-rigid arch supports like PowerStep Pinnacle, PowerStep, and CURREX. High-quality OTC insoles provide meaningful support, cushioning, and arch reinforcement for many patients. Their limitation is that they are designed for population averages—not your specific foot structure, pathology, or biomechanical needs. For patients with average foot mechanics and mild symptoms, premium OTC insoles may be entirely adequate. For patients with structural deformity, significant biomechanical abnormality, or conditions requiring precise correction, OTC insoles fall short.
When Do You Actually Need Custom Orthotics?
Custom orthotics are medically indicated—and provide clear added value over OTC options—in several clinical scenarios: Structural deformity (rigid flatfoot, cavus foot, severe pronation) where correction must be precise and structural. Diabetic foot protection where accommodative total-contact orthotics are required to eliminate pressure points and prevent ulceration. Leg length discrepancy requiring precisely calibrated heel lifts. Pediatric conditions requiring corrective prescription. Post-surgical cases requiring specialized offloading. Conditions failing OTC options after a genuine trial—if three months of high-quality OTC insoles haven’t resolved symptoms, it’s time for custom evaluation. High-mileage athletes with specific biomechanical demands and recurring injury patterns linked to foot mechanics.
When Are OTC Insoles Sufficient?
Many cases of mild plantar fasciitis, early Achilles tendinopathy, general arch fatigue, and walking/standing discomfort respond well to premium OTC insoles. Dr. Biernacki recommends a stepwise approach: try a high-quality OTC insole (PowerStep Pinnacle, PowerStep, CURREX) first for 6–8 weeks. If symptoms improve adequately, custom orthotics add expense without proportionate benefit. If symptoms persist despite compliant OTC insole use combined with appropriate exercises, custom evaluation is the logical next step.
The Evidence
Research comparing custom orthotics to prefabricated devices shows mixed results for mild-moderate plantar fasciitis—high-quality prefabricated devices perform comparably in many studies. For severe structural deformity, diabetic foot protection, and complex biomechanical presentations, custom orthotics demonstrate superior outcomes. The honest conclusion: the more complex and structural the problem, the stronger the case for custom devices. The milder and more functional the problem, the more likely OTC options will suffice.

✅ Pros / Benefits
- Stepwise approach (OTC trial first) saves patients money when prefabricated devices achieve adequate symptom control
- Custom orthotics provide clinically meaningful benefit for structural deformity, diabetic protection, and complex biomechanical cases
- Digital scanning technology improves custom orthotic precision over traditional foam box impressions
❌ Cons / Risks
- Custom orthotics are expensive (typically $300–$600) and insurance coverage is inconsistent—out-of-pocket cost is real
- Custom orthotics require break-in time and multiple follow-up adjustments—not a one-size-fits-all immediate fix
- Some patients are over-prescribed custom orthotics when high-quality OTC devices would achieve equivalent outcomes
Dr. Tom Biernacki’s Recommendation
I try to be honest with my patients about orthotics: custom devices are the right answer for a specific subset of patients, and OTC insoles are the right answer for many others. I recommend patients try PowerStep Pinnacle or PowerStep for 6–8 weeks before I prescribe custom orthotics—if the OTC trial resolves the problem, we saved them $400. If not, now I have a clear reason to proceed to custom evaluation. The patients who need custom orthotics—severe flatfoot, Charcot foot, complex diabetic management, post-surgical accommodation—they benefit enormously from a precisely prescribed device. The patients who have mild arch fatigue from standing all day? Premium OTC insoles are usually the answer.

Frequently Asked Questions
How much do custom orthotics cost in Michigan?
Custom foot orthotics from a podiatrist typically cost $300–$600 depending on materials, shell type, and accommodative modifications. Insurance coverage varies—some plans cover custom orthotics with documented medical necessity (diabetes, flatfoot, plantar fasciitis failing conservative care); others require significant out-of-pocket contribution. Dr. Biernacki’s office can assist with insurance pre-authorization requests.
How long do custom orthotics last?
Functional orthotics (rigid or semi-rigid shell with accommodative top cover) typically last 3–5 years with proper care. The top cover (EVA or leather surface) wears more quickly and may need replacement at 1–2 years while the shell remains functional. Pediatric orthotics may need replacement annually as children’s feet grow. Accommodative diabetic orthotics may require more frequent replacement due to material compression.
Are custom orthotics covered by Medicare?
Medicare Part B covers custom therapeutic shoes and inserts for qualifying diabetic patients under the Therapeutic Shoe Bill—but standard functional orthotics for plantar fasciitis or biomechanical conditions are generally NOT covered by Medicare as a standalone benefit. Dr. Biernacki’s staff can advise on specific coverage eligibility based on your Medicare plan and diagnosis.
How long does it take to get custom orthotics?
After the foot scan or casting appointment, laboratory fabrication typically requires 2–4 weeks. The dispensing appointment involves fit verification and initial break-in instructions. Most patients require one follow-up adjustment appointment at 4–6 weeks to fine-tune the device. Total time from evaluation to functional use is typically 6–8 weeks.
