Six battery-heated insole brands sold on Amazon have each drawn a CPSC Public Safety Warning since September 2025. They are Tajarly, iHeat, ZroeZroe, Coowalk/Coowali, Meisinuo, and Metasono/Meatsono. The two newest warnings, for Meisinuo and Metasono/Meatsono, came July 9, 2026.
Every notice cites the same hazard. Each insole’s internal lithium-ion battery can overheat, ignite, or explode, often even while switched off. CPSC has logged 82 combined incident reports and 64 reported burn injuries, several serious enough for hospital care.
No manufacturer has recalled its product or offered a refund. Anyone who owns one of these insoles should stop wearing it, confirm the brand, and dispose of the battery as hazardous waste. All six warnings remain open.

Latest Heated Insoles Recall Updates
July 9, 2026: CPSC Warns Consumers About Meisinuo Heated Insoles
CPSC issued Public Safety Warning #26-612 for Meisinuo heated insoles on July 9, 2026, citing 17 reports of fires and explosions [1]. At least 15 of those reports described a burn injury, some serious enough for hospital treatment.
About 1,372 units were sold on Amazon between August 2023 and December 2024 for $35 to $90. Meisinuo has not responded to CPSC’s requests for a recall or product information.
July 9, 2026: CPSC Warns Consumers About METASONO/MEATSONO Heated Insoles
The same day, CPSC issued Warning #26-613 for METASONO/MEATSONO heated insoles [2]: 14 reports of fires, explosions, or overheating had been logged. At least 10 led to a burn injury, some requiring skin-graft surgery.
CPSC counted 1,173 affected units sold on Amazon and eBay from July 2023 through July 2026 for $28 to $70 a pair. The manufacturer never answered CPSC’s outreach.
June 4, 2026: CPSC Warns Consumers About COOWALK/COOWALI Heated Insoles
CPSC issued Warning #26-533 for COOWALK/COOWALI heated insoles on June 4, 2026 [3], after receiving 26 reports of fire or explosion incidents. At least 23 resulted in a burn injury, several severe enough to need skin grafts.
About 6,000 units were sold on Amazon and GearTrade.com from August 2022 through May 2026. The manufacturer, based in China, has not cooperated with CPSC’s requests for a recall.
April 30, 2026: CPSC Warns Consumers About ZroeZroe Heated Insoles
CPSC warned consumers to stop using ZroeZroe heated insoles on April 30, 2026 [4], pointing to 10 reports of the insoles igniting or overheating. At least 4 of those incidents caused a burn injury requiring skin grafts.
The insoles were sold on Amazon and eBay, though CPSC’s notice does not state a sale period or price. The manufacturer has stayed unresponsive to CPSC’s requests.
September 4, 2025: CPSC Warns Consumers About Tajarly Heated Insoles
CPSC issued its first heated-insole warning of this group on September 4, 2025, covering Tajarly heated insoles [5]. Four reports described burn injuries from the insoles igniting, two requiring extended hospital stays.
Tajarly insoles sold on Amazon from July 2022 through July 2024 for $33 to $320. The Chinese manufacturer never replied to any of CPSC’s requests about the product or a recall.
July 10, 2025: CPSC Warns Consumers About iHeat Heated Insoles
CPSC warned consumers about iHeat heated insoles on July 10, 2025 [6], after 11 reports of the batteries catching fire or exploding. Eight of those reports involved a burn injury, some second- and third-degree.
iHeat insoles sold on Amazon from November 2022 through July 2024 for $48 to $80 a pair. The manufacturer, based in China, never answered CPSC’s requests for a recall.
Which Heated Insoles Are Affected?
CPSC’s six warnings, issued between September 2025 and July 2026, cover these heated insoles. Each is built with a remote-controlled lithium-ion battery in the heel:
- Tajarly: black insoles; “Tajarly” is printed on the sole and the purchase receipt; sold on Amazon July 2022 through July 2024.
- iHeat: black or red insoles; “iHeat” is printed on the sole and the receipt; sold on Amazon November 2022 through July 2024.
- ZroeZroe: black and red insoles; “ZroeZroe” appears as the brand or seller name on the purchase receipt; sold on Amazon and eBay.
- Coowalk/Coowali: black or red insoles marked “COOWALK” or “COOWALI”; sold on Amazon and GearTrade.com, August 2022 through May 2026.
- Meisinuo: black insoles marked “Meisinuo”; sold on Amazon, August 2023 through December 2024.
- Metasono/Meatsono: navy blue insoles with a multicolored design, marked “METASONO” on both sides; sold on Amazon and eBay, July 2023 through July 2026.
Check the sole imprint, the remote control, and any purchase receipt or Amazon order history. These details will confirm whether your insoles match one of these six brands.
Why Were Heated Insoles Recalled?
These six heated insole brands were effectively recalled – through CPSC Public Safety Warnings – because their batteries can catch fire or explode. This can happen even when the insoles are switched off, creating a serious burn and fire risk.
The battery sits directly against the skin inside a shoe. A failure can burn a wearer before the insole comes off.
CPSC’s own lithium-ion battery rulemaking calls this kind of failure “thermal runaway” [7]. An overheating cell ignites its electrolyte and can spread heat to neighboring cells in the pack.
None of the six manufacturers agreed to a recall or answered CPSC’s questions about the product. So CPSC used its public-warning authority instead of negotiating a company-run remedy.
Reported Incidents, Injuries, or Illnesses
CPSC has logged 82 combined reports of fires, explosions, or other thermal incidents across the six warnings. At least 64 of these reports described a burn injury, and no deaths have been reported in any of the six notices.
Coowalk/Coowali insoles account for the largest share: 26 reports and at least 23 burn injuries, several requiring skin grafts.
Meisinuo and Metasono/Meatsono each drew reports in the teens, and Tajarly’s four reports all described burn injuries, two requiring extended hospital stays.
These figures are reports CPSC received rather than a full count of every insole in use. They do not prove that every unit is defective or shares the same cause.
What Should Consumers Do?
Anyone who owns or suspects they own one of these six heated insoles should take these steps:
- Stop wearing the insoles immediately, even if they seem to be working normally.
- Confirm which of the six brands you own before deciding what to do with it next.
- Do not throw the insoles or battery in the trash or curbside recycling. Take them to a household hazardous waste center, calling ahead to confirm it accepts lithium-ion batteries.
- Report the incident to CPSC at SaferProducts.gov. You can also call CPSC’s Consumer Hotline at 800-638-2772 (TTY 800-638-8270), 8 a.m. to 5:30 p.m. ET.
- Seek medical care for any burn, and keep the insoles, packaging, and medical records if you were injured.
Legal Options
A CPSC warning does not automatically establish liability or eligibility for compensation. It is not the same as a company-issued recall.
No multidistrict litigation has formed for heated insoles, per the JPML‘s docket [8]. People hurt by one of these products are filing individual claims rather than joining a class action.
An individual case review is the way to find out whether your facts support a claim. See the Tajarly heated insoles and Meisinuo heated insoles lawsuit pages for more.
Filing Deadlines
State law sets the filing deadline for a product-liability claim, and that deadline is not the same in every state.
How long you have depends on when you discovered your injury and its cause. Some states start the clock at diagnosis instead of the incident date.
Missing a deadline can end an otherwise strong claim. Anyone hurt by one of these insoles should check with a lawyer promptly rather than wait.
Frequently Asked Questions
What If My Battery-Heated Insoles Are a Different Brand?
If your battery-heated insoles are a different brand, CPSC has not issued a warning for it. The same lithium-ion battery hazard can still apply, so treat overheating, swelling, or an unusual smell as a warning sign no matter which brand you own.
What Is the Price Range Across the Six Recalled Heated Insole Brands?
The price range across the six recalled heated insole brands runs from about $28 to $320, published only for Metasono/Meatsono (low), Tajarly (high), iHeat, and Meisinuo. ZroeZroe and Coowalk/Coowali’s notices state no price.
Did Amazon Take Any Action After These Burn Injury Reports?
Amazon did take action after these burn injury reports in at least one documented case. After a Minnesota man’s heated insole burned his foot in December 2024, Amazon removed the listing and told a reporter it was investigating.
Is CPSC Addressing Lithium-Ion Battery Fire Risk Beyond These Six Insole Brands?
CPSC is addressing lithium-ion battery fire risk beyond these six insole brands. On June 24, 2026, it proposed a Safety Standard for Lithium-Ion Batteries Used in Micromobility Products, like e-bikes and scooters. That rule does not cover heated insoles.
What Evidence Should I Keep If a Heated Insole Burned Me?
The evidence to keep if a heated insole burned you starts with the insole and its battery. Keep them instead of returning them to the manufacturer, and add the original packaging, purchase or order records, photographs of the injury, and medical records.
Do These CPSC Warnings Cover Heated Socks Too, or Just Insoles?
These CPSC warnings cover heated insoles only, not heated socks or other apparel. Each of the six actions names the product as “heated insoles,” not “heated socks” or another footwear-warmer term.
When Should I Seek Emergency Care for a Heated Insole Burn?
You should seek emergency care for a heated insole burn that appears serious rather than minor. CPSC’s reports describe several burns serious enough to require hospital treatment, so do not wait for it to worsen.
