Latest Updates
On July 9, 2026, the CPSC issued a product safety warning urging consumers to immediately stop using and dispose of Meisinuo heated insoles due to the risk of serious burn injury and fire [1]. The seller, Meisinuo, has not agreed to recall the insoles or provide a remedy to consumers. Federal law prohibits any person from selling products subject to a CPSC safety warning of this nature.
What Product Is Affected?
The warning covers Meisinuo heated insoles — black insoles containing a lithium-ion battery in the heel area, operated by a remote control. Approximately 1,372 units are affected.
The defective insoles were sold exclusively on Amazon.com from August 2023 through December 2024 for between $35 and $90. They were manufactured in China by the seller identified as Meisinuo.
What Is the Hazard?
The internal lithium-ion battery inside the recalled Meisinuo heated insoles can explode and ignite during use, posing a serious risk of burn injury and fire. Because the battery is embedded in the heel of an insole worn directly against the foot inside a shoe, a battery explosion or ignition can cause immediate and severe burns to the foot with no opportunity for the user to react.
Incidents and Injuries
The CPSC is aware of 17 reports of fires, explosions, and other thermal incidents involving the Meisinuo heated insoles. Those incidents have resulted in at least 15 reported burn injuries, including serious second- and third-degree burns that required hospital treatment.
No Recall, No Remedy — What That Means for Consumers
Unlike most product safety situations where the manufacturer cooperates with the CPSC and provides a refund or replacement, Meisinuo has refused to issue a recall or offer consumers any remedy. That refusal does not leave injured consumers without legal options — it may actually strengthen the case against the company and against Amazon as the platform that sold the product.
Under product liability law, retailers and online platforms that sell dangerous products can face liability regardless of whether the manufacturer cooperates with regulators. Attorneys investigating these claims are actively pursuing cases against both the sellers of defective heated insole products and the platforms that made them available to consumers.
What Should Consumers Do?
The CPSC urges consumers to dispose of the defective Meisinuo heated insoles immediately and follow local hazardous waste disposal procedures. The defective lithium-ion battery must not be placed in regular trash, curbside recycling bins, or standard retail battery drop-off boxes.
Consumers should contact their municipal household hazardous waste (HHW) collection center ahead of time to confirm it accepts defective lithium-ion batteries before bringing the product in for disposal. Any incidents involving injury or product defects should be reported to the CPSC at www.SaferProducts.gov, or by calling the CPSC hotline at 800-638-2772 (TTY 800-638-8270), available Monday through Friday, 8:00 a.m. to 5:30 p.m. ET.
Can I File a Lawsuit?
Consumers who suffered burn injuries from Meisinuo heated insoles that exploded or ignited — particularly those who required medical treatment for second- or third-degree burns — may have significant legal options against the seller, importer, and online platform. A class action lawsuit could allow affected consumers to seek compensation for medical expenses, hospitalization costs, pain and suffering, permanent scarring or disfigurement, lost wages, and other related losses. Contact an attorney as soon as possible to learn more about your rights.
