Heated Insole Burn Injuries: What the CPSC Warnings Mean

If you bought battery-powered heated insoles to keep your feet warm on job sites, in deer stands, or on cold-weather walks, federal safety regulators have a message you should not ignore: some of these products can explode and catch fire — even when they are switched off.

In early July 2026, the U.S. Consumer Product Safety Commission (CPSC) issued urgent warnings covering two brands of heated insoles sold through major online marketplaces, after dozens of reported fires, explosions, and serious burn injuries. Because heated insoles sit directly against your body, a battery failure can mean a deep, painful heated insole burn injury in a matter of seconds.

This article explains what the warnings say, why they are different from an ordinary recall, what to do with heated insoles you may own, and what legal rights you may have if a defective product has burned you or someone you love.

What the New CPSC Warnings Say

On July 9, 2026, the CPSC told consumers to immediately stop using two lines of heated insoles sold online:

• Meisinuo heated insoles. According to the CPSC, the lithium-ion battery in the heel area can explode and ignite. The agency cited 17 reports of fires, explosions, and other thermal incidents, resulting in at least 15 reported burn injuries — including serious second- and third-degree burns that required hospital treatment. The insoles were sold on Amazon.com from August 2023 through December 2024.

• METASONO/MEATSONO heated insoles. The CPSC cited 14 reports of fires, explosions, and other thermal incidents, with at least 10 reported burn injuries — including second- and third-degree burns that required skin grafts. These insoles were sold on Amazon.com and eBay.com from July 2023 through July 2026.

Most alarming, the agency reports that the batteries in these products can fail even when the insoles are turned off. That means the danger is not limited to when you are wearing them. Insoles sitting in a closet, a gym bag, or a garage can still ignite.

A Warning Is Not the Same as a Recall — and That Matters

In a typical recall, the company agrees to a remedy: a refund, a repair, or a replacement, along with contact information so you can make it right. These heated insole announcements are different. The CPSC issued public warnings, which the agency generally does when it cannot secure a cooperative recall — often because the product was sold by an overseas or third-party marketplace seller that regulators cannot reach.

Neither warning lists a company contact or any remedy. Instead, the CPSC's guidance is blunt: stop using the insoles and dispose of them following your local hazardous-waste procedures.

This is also not the first time regulators have flagged this category. The CPSC has previously issued similar stop-use warnings for other heated insole brands sold online, including iHeat, Tajarly, and ZroeZroe. The pattern points to a broader problem: inexpensive, battery-powered wearables sold by sellers who effectively disappear when something goes wrong.

Why Lithium-Ion Batteries Worn on Your Body Are Especially Risky

A lithium-ion battery packs a large amount of energy into a small package. When a battery is poorly made or damaged, one overheating cell can set off the cells around it — think of a single falling domino tipping the whole row. Engineers call this "thermal runaway," and it can take a battery from warm to burning in moments.

When that happens to a phone on a table, you have a fire hazard. When it happens inside your boot, there is a direct path to a serious injury. Footwear traps heat and flames against the skin, and a laced-up boot takes precious time to remove. That is why the reported injuries in these warnings are so severe: second-degree burns blister and damage the deeper layers of skin, while third-degree burns destroy the skin's full thickness and often require skin grafts. Burns to the feet can also mean infection risk, months of recovery, and lasting damage that affects how you walk and work.

What to Do If You Own Heated Insoles

• Stop using them immediately, and do not charge them. Charging is when many battery failures occur.

• Check the brand. The current warnings cover Meisinuo and METASONO/MEATSONO insoles. If your insoles are unbranded or from an unfamiliar online seller, treat them with caution.

• Dispose of them properly. Follow your local hazardous-waste procedures for lithium-ion batteries. Never put them in the regular household trash, where they can start fires in garbage trucks and waste facilities.

• Do not resell or donate them. Passing along a hazardous product puts someone else at risk.

• Report any incident to the CPSC at SaferProducts.gov.

• If you were burned, get medical care first — then preserve the evidence. Keep the insoles, the packaging, your order confirmation or receipt, and photos of your injuries. Do not throw the product away; it may be the single most important piece of evidence in any claim. Store it safely away from anything flammable, ideally in a metal container.

Heated Insole Burn Injuries and Your Legal Rights

Product liability law exists for exactly this situation. Manufacturers, distributors, and sellers can be held responsible when an unreasonably dangerous product injures someone using it as intended. A successful claim may cover medical bills, lost income, pain and suffering, and compensation for scarring or disfigurement.

We will be honest about the challenge here: many of these products were sold by overseas third-party sellers that are difficult to locate, which is precisely why the CPSC could not obtain a traditional recall. But an unreachable seller does not always mean there are no options. Depending on the facts of your case, other parties in the product's chain of distribution may bear legal responsibility. Sorting that out requires investigation, and it is one of the most important things an experienced product liability attorney does.

Timing matters, too. In Texas, most personal injury claims must generally be filed within two years, but exceptions exist and deadlines vary by state and situation. The safest move is to talk with an attorney promptly rather than assume you have time.
