Are 3D-Scanned Insoles Worth the Hype? What Athletes Should Know

Are 3D-Scanned Insoles Worth the Hype? What Athletes Should Know in 2026

Quick take: 3D-scanned custom insoles can help some athletes with specific biomechanical issues, but they are not a universal performance panacea — and The Verge’s skeptical take on “placebo tech” is a useful reality check. If you’re investing, know what problems you want to solve, how to validate results, and how custom insoles change what you need from your gym or travel bag (ventilated shoe compartments, insole storage, odor control).

Hook: Your feet matter — and so does what you carry them in

If you spend money on training shoes, recovery tools, or monthly subscriptions to recovery tech, the promise of a near-tailored insert shaped by a 3D scan is seductive. Athletes’ biggest pain points — pain, poor shoe fit, blisters, and performance inconsistency — get targeted by that “custom” label. But between marketing copy and clinical reality sits a gray area: some athletes feel huge benefits, others see nothing. And as brands push direct-to-consumer (DTC) 3D scanning and mass customization in 2025–26, your decision has downstream effects on how you pack and carry your gear: not just shoes, but spare insoles, drying strategies, and anti-odor systems in your bag.

What The Verge’s skepticism tells us — and why it matters

“This 3D-scanned insole is another example of placebo tech.” — Victoria Song, The Verge, Jan 16, 2026

The Verge’s recent hands-on skepticism is a timely reminder that consumer tech and wellness often conflate personalization with proven clinical benefit. Many DTC brands now use smartphone scans, AI-driven foot models, and carbon-fiber overlays to justify higher prices. The question for athletes is simple: does the technology solve your specific problem better than a quality prefabricated insole or a well-fitted shoe?

Bottom line up front: When 3D-scanned insoles are worth it

• Worth it if you have a diagnosed structural or biomechanical issue (e.g., symptomatic overpronation, neuroma-related pressure points, persistent plantar fasciitis) and you’re seeking a custom medical approach.
• Potentially helpful if you’re a dedicated runner, triathlete, or athlete with high training volume who wants a fit-step optimized for comfort and durability.
• Not worth it if you expect dramatic performance gains simply from a scan, or if your issue is general foot fatigue that can be improved with better shoes, socks, or simple prefabricated insoles.

How the landscape evolved by 2026

The last two years accelerated a trend that began earlier in the decade: smartphone 3D scanning, AI gait estimation, and DTC manufacturing scaled rapidly in late 2024–2025. Startups moved from “clinic-only” molds to pop-up scans in gyms, shoe stores, and even airports. At the same time, clinicians and journalists — including The Verge — pushed back, highlighting inconsistent outcomes and the potential for a placebo effect. Insurers and some sports medicine groups began asking for stronger clinical validation before covering high-cost custom orthotics.

Key 2025–26 trends to watch

• Wider availability of consumer 3D scanning kiosks and app-based scans at retail.
• Increased integration of gait data from wearables (smartwatches, pressure mats) into insole prescriptions.
• More hybrid services: scans done by DTC brands, validation by podiatrists or physical therapists.
• Regulatory scrutiny and calls for better clinical outcome data for DTC orthotics.

Evidence vs. placebo: what the science and clinicians say

Clinical studies over the past decade show a mixed picture. Prefabricated and custom insoles both reduce pain for some conditions, but effect sizes vary. Importantly, the placebo response is real in orthotics — when someone believes a device is custom and premium, perceived comfort and pain can improve. That doesn’t make benefits irrelevant, but it does mean you should demand measurable outcomes.

How to differentiate real benefit from placebo

1. Set objective baselines: record pain scores, weekly mileage, or time trial times before trying insoles.
2. Ask for an adaptation period and retest — many providers offer a 4–8 week follow-up window to evaluate changes.
3. Look for measurable gait or pressure changes if your provider uses force plates or pressure mapping — not just a nicer insole.
4. Prefer solutions that involve a clinician when you have a medical condition: a podiatrist or physical therapist can help rule out confounders.

Types of insoles in 2026 — where 3D-scanned fits in

Consumer choices now split into three practical categories:

• Prefabricated high-performance insoles — brands like SuperFeet, Currex-type models, and sport-specific foam/gel combinations. Low cost, immediate fit, good for general comfort.
• 3D-scanned DTC custom insoles — smartphone scans or in-store kiosks produce a digital model that’s milled, 3D-printed, or layered. Mid-to-high price. Promises better contouring and materials.
• Clinic-molded orthotics — gold standard for medical issues: physical casting, direct clinician oversight, adjustable shells, and thorough clinical follow-up. Highest price, best for pathology.

Materials and features to prioritize

Not all custom insoles are built the same. When evaluating options, inspect these elements:

• Shell material: Stiffer shells (polypropylene, carbon fiber) provide motion control; softer shells (EVA, PU) offer cushioning. Match stiffness to your needs — aggressive control for overpronators, softer for long-distance comfort.
• Topcover and lining: Antimicrobial, moisture-wicking covers reduce odor and friction — essential for gym and travel use.
• Thickness and drop: Thicker insoles may change shoe fit and stack height. Check compatibility with your shoe’s volume.
• Heel cup depth: Deeper cups stabilize the calcaneus and improve proprioception; shallow cups are more flexible but less supportive.
• Replaceability: Modular designs with removable topcovers or interchangeable pads extend life and allow travel-friendly options.

Sizing and shoe fit: the overlooked puzzle piece

One practical reason some people don’t benefit is simple poor shoe fit. Adding a custom insole changes internal volume and may make an otherwise perfect shoe too tight. Conversely, in low-volume shoes insoles can create hotspots and friction. Consider these sizing tips:

• Bring the shoes you plan to use when getting scanned or molded — many providers request this.
• Expect to need a slightly larger shoe size or different width if your custom insole has high arch or thick padding.
• Test insoles in a run or training session before a race or long trip. The insole should feel like an integrated part of the shoe within a week.

How custom insoles change what you need from a gym or travel bag

Custom insoles aren’t just about your feet — they affect how you pack and manage shoes. Here’s a checklist of bag features and habits that make sense if you use or travel with custom insoles.

Essential bag features

• Dedicated ventilated shoe compartment: A tunnel or external shoe pocket separates shoes and insoles from clean clothes and speeds drying.
• Removable insole pouch or pocket: A small, breathable pouch prevents deformation and keeps spare insoles flat during travel.
• Ventilation and anti-odor lining: Bags with antimicrobial linings or odor-control zippers help when you pack used shoes and insoles post-workout.
• Compression straps and shoe trays: Prevent shoes (and insoles) from pressing into other gear and preserve insole shape.
• Structured base: Keeps shoes from crushing softer items and maintains insole geometry.

Packing and maintenance practices

1. Store spare or travel insoles flat in a dedicated pouch — never crumpled in a shoe or pocket.
2. Air-dry used insoles before packing. If your bag lacks ventilation, use a small mesh pouch under the bag’s shoe compartment zipper.
3. Rotate insoles by activity: keep a cushioned pair for long runs, a stiffer pair for speed/interval sessions.
4. Consider carrying a thin backup prefabricated insole — useful if your custom one needs repair or you’re switching shoe types.

Comparing price, turnaround, and warranty

Costs vary widely:

• Prefabricated: $20–$70
• DTC 3D-scanned customs: $100–$300
• Clinic-molded orthotics: $300–$700+

Turnaround times also differ. DTC brands often promise 1–3 week delivery; clinics may take longer due to customization and fittings. Warranty and satisfaction guarantees matter: look for at least a 60–90 day adjustment window or exchange policy, and clear language on remakes if you change shoes or your symptoms don’t improve.

Practical buying guide — a step-by-step checklist

1. Define the problem. Is it pain, shoe fit, performance, or prevention? If pain is severe or lasts >6 weeks, consult a podiatrist first.
2. Choose the service level. Prefab for simple comfort; DTC 3D-scan for improved contouring; clinic-molded for pathology.
3. Bring shoes to the scan. Scan with the shoes you’ll use most to match volume and heel-to-toe drop.
4. Request objective baseline measures. Ask the provider for pressure mapping, gait video, or performance metrics so you can compare later.
5. Follow an adaptation protocol. Build wear time gradually (1–2 hours extra per day) and log changes in comfort and performance.
6. Retest and validate. After the adaptation period, compare your baseline metrics and subjective scores. Use your provider’s return/remake window if results are unsatisfactory.

Case studies from athlete archetypes (real-world examples)

Here are three condensed, experience-based scenarios that show how outcomes vary.

1) The marathoner with chronic plantar pain

Background: 40–50 mpw runner with plantar pain for 9 months. Tried shoes and rehab without relief. Outcome: Clinic-molded orthotic prescribed after a gait exam reduced pain and allowed gradual return to mileage. The customized arch support redistributed pressure; the athlete used structured duffel with ventilated shoe compartment and kept a spare insole in a flat pouch for travel races.

2) The weekend warrior chasing comfort

Background: Casual gym-goer with no diagnosed pathology but comfort complaints in cross-trainers. Outcome: A $40 prefabricated insole or a $120 DTC scanned insole both improved comfort. The DTC option was nicer but not dramatically better. Key takeaway: unless you have a structural issue, spend on better shoes first.

3) The commuter athlete balancing gym, work, travel

Background: Daily commute, gym sessions, occasional travel. Outcome: Opted for a mid-range DTC custom insole with antimicrobial topcover. Bag choices mattered: a backpack with external ventilated shoe pocket and an insole pouch reduced odor and kept insoles from being crushed during flights.

When to involve a podiatrist

Consult a clinician if you have:

• Persistent or worsening pain
• Neurologic symptoms (numbness, tingling)
• History of foot fractures, diabetes, or circulatory issues
• Structural deformities (severe bunions, hammertoes)

Podiatrists can order imaging, perform manual casting, and provide follow-ups — things a DTC scan alone cannot replicate.

Practical takeaways — what to do next

• If you have a medical issue, see a podiatrist first. Use DTC scans as a complement, not a replacement.
• Set objective benchmarks before you start so you can detect placebo vs. real change.
• Choose bag features that preserve insole shape and hygiene: ventilated shoe tunnels, insole pouches, structured bases, and antimicrobial linings.
• Be skeptical of marketing claims. Prefer services that offer measurable gait or pressure data and at least a 60–90 day trial.
• Rotate insoles by activity and pack spares flat — never crumpled.

Future predictions: Where podiatry and tech collide next

Through 2026 and beyond, expect the following developments:

• Hybrid care models that combine DTC scans with clinician sign-off to improve outcomes and credibility.
• Better outcome tracking: apps that integrate training data, pain logs, and pressure maps to quantify benefit and rule out placebo.
• Improved materials and modular designs that allow athletes to swap stiffness or cushioning elements depending on activity.
• Insurance and sports-med organizations pushing for higher evidence standards for reimbursing high-cost custom orthotics.

Final verdict — balance hope with evidence

3D-scanned insoles represent a useful evolution in personalized gear, especially for athletes with clear biomechanical needs. But The Verge’s skepticism is a healthy caution: not every shiny, scanned insert will transform your training. Treat customization as one tool in a broader toolkit that includes the right shoes, strength training, and, when necessary, clinical care.

Actionable next steps

1. Identify the problem you want to solve and collect objective baselines now.
2. Test a prefabricated insole before committing to an expensive custom option if your need is comfort rather than pathology.
3. If you go custom, demand objective gait/pressure data, a clear adjustment window, and a bag with a ventilated shoe compartment and dedicated insole storage for travel.
