How to Teach Clients to Spot Misleading 'Custom' Claims in Wellness Tech

Can you trust a "custom" wellness gadget? How to spot misleading claims in 2026

It’s easier than ever to be dazzled by a shiny demo: a quick 3D scan, a slick app, and a promise of personalized relief. But when that “custom” solution costs hundreds of dollars and becomes part of your care plan, what separates genuine, evidence-based personalization from marketing dressed up as medicine? This guide gives clients and caregivers a concise, practical checklist to unmask misleading “custom tech” claims—using the 3D insole story from early 2026 as a teaching case.

Why this matters now (most important points first)

In late 2025 and early 2026 regulators, researchers, and journalists ramped up scrutiny of wellness devices that make medical or therapeutic promises without rigorous evidence. The Verge’s January 2026 write-up about a popular start-up that used smartphone 3D scans to sell “custom” insoles illustrated a growing pattern: tech can create the appearance of personalization while delivering generic or placebo-level results.

Bottom line: Consumers need clear red flags, specific questions to ask, and easy verification steps so they can buy—or decline—custom tech with confidence.

Quick checklist: 10 red flags of misleading "custom" tech

• Vague personalization: Your product is “customized” but only receives a cosmetic engraving or a name on a label.
• No independent validation: Claims of clinical benefit without peer-reviewed studies or third‑party testing.
• Opaque algorithms: The company touts a “proprietary algorithm” but won’t describe inputs, outputs, or training data — consider whether they run models in-house or leverage local model stacks like a local LLM lab for inference.
• Bracelet of testimonials: Lots of glowing customer stories but no controlled trials or before/after objective measures.
• Short, dramatic demos: One-off in-store scans with thermographic or gait footage but no sustained follow-up data.
• No qualified clinician involvement: No podiatrist, orthotist, physical therapist, or licensed clinician signs off on the prescription.
• Marketing language that sidesteps regulation: “Not a medical device” while explicitly promising pain relief or correcting biomechanics.
• Tight refund windows: Short trials, no fit guarantees, and strict return rules that make post-purchase testing impossible.
• Data privacy silence: Poorly worded or missing privacy policy for sensitive biometric scans — see our primer on protecting client privacy when using AI tools.
• Unclear manufacturing claims: Materials, durability, and standards (e.g., ASTM, ISO) are absent or unverified.

Case study: The 3D insole demo that felt custom—but wasn’t

In January 2026 a widely-read technology review recounted an experience common across the wellness tech landscape: a CEO used a smartphone to scan bare feet, promised a biomechanical analysis, and delivered a printed insole labeled “custom.” The reviewer reported minimal difference between those insoles and standard off-the-shelf inserts—suggesting a strong placebo component.

What went wrong, and what could the buyer have asked up front? We turn that experience into a practical checklist clients can use in any modality that claims “custom” personalization.

What to ask before you buy or book

Use these questions in-store, on a sales call, or while researching online. Ask for concise, verifiable answers.

1. What makes this product truly "custom"? (Is it a scan-fed design change or a stamped label?)
2. Who interprets the scan? (A clinician, a certified orthotist, or an automated model?)
3. What objective measurements will be used? (Pressure mapping, gait lab metrics, pre/post pain scales.)
4. Do you have peer-reviewed evidence? (Provide study citations, not marketing summaries.)
5. Is this registered with regulatory bodies? (FDA 510(k) clearance, EU CE under MDR, ISO 13485 certificate?) — if they cite FDA 510(k), ask for the submission number and verification in official databases like the FDA's listings; if they can't provide it, be skeptical.
6. How is my scan stored and protected? (Where are the files stored, who can access them, retention policy?)
7. What is the trial or refund policy? (How long to test, who pays return shipping, fit guarantees?)
8. Who manufactures and what materials are used? (3D-print technology, material specs, lifecycle and warranty.)
9. What follow-up is included? (Fit adjustments, clinician review, long-term outcomes tracking.)
10. Can I see raw pre/post data? (Pressure maps, step counts, pain surveys.)

How to verify claims: 7 practical checks you can do in 10–30 minutes

You don’t need to be a researcher. Use these quick verifications to separate substance from spin.

1. Search for registered studies: Look on ClinicalTrials.gov and PubMed for the company name, product name, and lead investigators. Registered trials and peer-reviewed results are strong signals.
2. Check regulatory databases: Use the FDA 510(k) database for US clearances (search product or company), and the EU NANDO/CE database for notified-body references. If they claim a medical benefit but have no registration, be skeptical.
3. Validate ISO and safety certificates: Ask for certificate numbers and verify them with the issuing body. ISO 13485 indicates a medical device quality system; IEC 60601 suggests electrical safety testing for powered devices.
4. Ask for an independent lab report: Independent biomechanical or material testing (third-party labs, university partners) is more reliable than in-house tests.
5. Inspect the study design: If a study is cited, check for sample size, control groups, blinding, objective endpoints, and effect sizes—not just p-values.
6. Request a live demo with objective measures: Ask them to show baseline pressure maps and a follow-up after your trial wear. No objective change? Question the personalization claim.
7. Read the privacy policy closely: Are scans identifiable? Is data shared with partners? Who controls deletion requests—are they compliant with GDPR/CCPA/HIPAA where applicable? For a short privacy checklist see our note on protecting client privacy.

Certification cheat sheet: what each badge actually means

Not all badges are equal. Here’s what to look for and what they do—and don’t—guarantee.

• FDA 510(k) clearance: Product is substantially equivalent to a marketed device. It does not automatically prove superiority, but it does require technical testing and evidence of safety.
• FDA De Novo / PMA: Stricter pathways for novel devices—stronger evidence required. Rare for simple wellness products.
• CE mark (MDR): Indicates conformity with EU medical device rules. Verify the notified body and certificate number—some companies misuse the CE logo.
• ISO 13485: Quality management for medical device manufacturers. Ask to see the certificate and verify issuance date and scope.
• IEC 60601: Safety standard for electrical medical equipment. Relevant if the device is powered.
• Clinical trial registration: Trials listed on ClinicalTrials.gov or EUCTR with completed results and peer-reviewed publications are strong validation.

Interpreting evidence: what good proof looks like

Evidence matters most when it answers the question, “Does this product change outcomes that matter to me?” Here’s how to evaluate studies and claims.

• Objective endpoints: Pressure distribution, gait asymmetry, validated pain scales, return-to-activity timelines—these are more meaningful than transient subjective impressions.
• Control groups and randomization: Placebo effects are powerful for pain and comfort claims. Randomized controlled trials reduce bias.
• Sample size and replicability: Small pilot studies are useful but not definitive. Look for multiple independent studies or replication by universities.
• Real-world outcomes: Longitudinal data on durability, compliance, and long-term symptom change beats one-week demo studies.
• Transparency: Open methods, publicly available datasets, and pre-registered study protocols signal higher trustworthiness.

Privacy, data, and AI: what to watch for in 2026

By 2026 AI-driven personalization is common. That increases both promise and risk. Pay attention to three privacy and AI-specific points:

1. Model explainability: Ask how the AI uses your scan. Can the company explain factors driving the recommendation, not just show a score? If they rely on personalization signals and edge analytics, resources like Edge Signals & Personalization can clarify typical data flows.
2. Data reuse & sharing: Will your biometric scans be used to train models? Is your consent granular and revocable? Ask whether scans are used for training or kept isolated.
3. De-identification and breach policies: High-resolution foot scans can be biometric identifiers. Confirm deletion pathways and breach notification timelines — or consider vendors that offer local inference rather than cloud training (see options like a local LLM lab).

How therapists and caregivers can support clients

If you’re a practitioner advising a client, use this short protocol during consultations:

1. Clarify the clinical question: What functional problem are we trying to solve? (Pain, gait, balance)
2. Demand objective baseline: Record pre-intervention measures (pressure maps, ROM, strength, validated pain scale).
3. Insist on clinician review: If a device claims a clinical outcome, make sure it’s evaluated by a licensed professional — consider routing such cases into a micro-clinic or pop-up evaluation program like the micro-clinics & pop-up pediatric outreach playbook.
4. Structure a trial: Time-limited trial with objective follow-up measures and a return policy.
5. Document outcomes: Track compliance, symptom change, and any adverse effects for 6–12 weeks.

Future trends: what to expect in the next 2–3 years

Regulation and consumer tools are catching up to hype. Expect these developments through 2027:

• Greater regulatory clarity: More apps and devices that claim therapeutic effect will require medical classification and clinical data.
• Verified marketplaces: Platforms will begin offering verified badges for evidence-backed products—look for third-party validators.
• Insurer scrutiny: Payers will demand objective proof for reimbursement of “custom” devices, driving better trials and standardized outcomes.
• Third-party audits: Independent clinical labs and universities will increasingly publish replication studies of popular consumer devices.

"In a world of polished demos, insist on data, clinician oversight, and a trial window. Custom should mean measurable benefit, not just bespoke packaging."

Action plan: a 7-step consumer roadmap

Follow these steps before handing over payment or booking a fitting appointment.

1. Ask the 10 questions above and write down the answers.
2. Request supporting documents: Study citations, certificates, and the privacy policy.
3. Verify certificates online: Check FDA, PubMed, ClinicalTrials.gov, and ISO issuers.
4. Insist on an objective baseline test and a trial with documented follow-up.
5. Confirm clinician involvement by name and license number.
6. Read the fine print: Returns, refunds, and warranty conditions.
7. Delay purchase if uncertain: If answers are evasive, walk away—come back when evidence is clear.

Real-world example: what a better insole evaluation looks like

Imagine a different company. You get a 3D scan, but the process includes:

• a pre-fit pressure map and validated pain score,
• a licensed podiatrist reviewing the scan and signing off on design changes,
• a randomized pilot trial showing clinically meaningful change in gait symmetry or pain at 12 weeks,
• a 90-day fit trial and full refund policy, and
• an explicit privacy contract that your scans won’t be used for AI training without opt-in consent.

That’s the baseline for a claim of “custom” with clinical intent. Demand the same clarity.

Final takeaways

Consumers and caregivers don’t have to accept marketing spin. In 2026 the landscape is shifting: more companies will offer true, evidence-based customization, but many will still rely on placebo-grade personalization and opaque AI claims. Use objective measures, insist on clinician oversight, verify certifications, and insist on trial periods.
