Latest Meisinuo Heated Insoles Recall and Lawsuit Developments

December 2025
- December 3, 2025 – A federal personal-injury product-liability complaint was filed against Amazon.com Inc. and Meisinuo in the Western District of Oklahoma as Caddell v. Amazon.Com Inc. et al., Case No. 5:25-cv-01451. The docket identifies the matter as a personal-injury product-liability action and does not constitute a finding that either defendant is liable [3]
What Are Meisinuo Heated Insoles?
Meisinuo Heated Insoles are black battery-powered shoe inserts designed to warm a user’s feet. CPSC says the products contain an internal lithium-ion battery in the heel area and are operated by a remote control.
The insoles were sold through Amazon.com from August 2023 through December 2024 for between $35 and $90. They were manufactured in China.
Because the battery is built into the heel area, a thermal failure can occur close to the wearer’s foot, shoe, sock, and surrounding clothing.
Why Did CPSC Warn Consumers to Stop Using Them?
CPSC says the lithium-ion battery can explode and ignite. A failure can expose the wearer to intense heat, flame, smoke, and fire inside or immediately around the shoe.
The July 2026 action is a CPSC product safety warning rather than a cooperative recall with a manufacturer-provided refund or replacement.
Meisinuo has not agreed to recall the products or offer a remedy, so CPSC advises consumers to stop using the insoles and follow local hazardous-waste disposal procedures.
How Many Incidents and Injuries Have Been Reported?
CPSC is aware of 17 fires, explosions, and other thermal incidents involving Meisinuo Heated Insoles.
Those incidents resulted in at least 15 reported burn injuries. CPSC specifically identifies serious second- and third-degree burns requiring hospital treatment.
The warning does not provide detailed medical histories for each injured consumer. Individual cases should therefore rely on the specific medical records and incident evidence involved.
What Is the Current Meisinuo Heated Insoles Lawsuit Status?
A federal lawsuit naming Meisinuo and Amazon.com Inc. was filed on December 3, 2025, in the U.S. District Court for the Western District of Oklahoma. The public docket categorizes Caddell v. Amazon.Com Inc. et al. as a personal-injury product-liability case.
Amazon filed an answer in January 2026. On May 11, 2026, the court granted the plaintiff 90 additional days to serve Meisinuo.
The May order states that the plaintiff and Amazon were attempting an early resolution. The cited court materials do not establish what occurred after that order, so this page does not characterize the action as settled, dismissed, or otherwise resolved.
What Does the Caddell Lawsuit Establish?
The existence of a lawsuit establishes that at least one individual federal product-liability action has publicly named Meisinuo. It does not establish that Meisinuo, Amazon, or another party is legally responsible for an individual consumer’s injuries.
Allegations in a civil complaint are claims made by the plaintiff rather than judicial findings. Liability must be established through the evidence and applicable law or resolved by agreement between the parties.
The cited docket is an individual personal-injury action and should not be treated as evidence that a class has been certified or that an MDL has been created.
How Can the Battery Failure Cause Injury?
A failure may produce heat, flame, or an explosion inside the heel portion of the insole. Because the device is worn inside a shoe, a consumer may have limited time to remove it after a thermal event begins.
The shoe and sock can also keep the heated device close to the skin while the wearer attempts to respond.
An investigation may examine the battery cell, charging components, wiring, insulation, heel enclosure, remote-control system, warnings, and physical condition of the insole.
What Injuries Have Been Associated With the Insoles?
CPSC specifically reports serious second- and third-degree burns requiring hospital treatment. The agency does not identify the precise location or treatment course for every reported injury.
Depending on the individual event, medical records may document emergency treatment, hospitalization, wound management, surgery, rehabilitation, or follow-up treatment.
Potential claims should be based on the consumer’s actual diagnosis, treatment, prognosis, and documented losses rather than assumed medical outcomes.
Why Foot Burns Can Affect Daily Activity
The feet bear body weight and are involved in standing and walking. A significant heel or foot burn can therefore affect mobility during recovery.
Restrictions on walking, standing, work, exercise, or footwear should be documented through treating providers rather than presumed from the injury alone.
Medical records, work restrictions, photographs, and rehabilitation records may help document the practical effects of an injury.
Who May Be Affected?
Potentially affected consumers include people who purchased or used black Meisinuo Heated Insoles sold through Amazon.com from August 2023 through December 2024.
Other people may also be affected if an insole explodes or ignites near them. Family members, coworkers, roommates, or bystanders may be exposed to smoke, flame, or resulting property damage.
Property losses may include damaged shoes, socks, clothing, flooring, furniture, bedding, vehicles, or other items affected by the incident.
Who May Be Liable?
Potentially responsible parties may include Meisinuo, a manufacturer, battery-cell supplier, component supplier, distributor, seller, marketplace entity, or another business involved in placing the product into commerce.
Potential legal theories may include defective design, manufacturing defects, inadequate warnings, negligence, breach of warranty, or other claims available under applicable law.
The CPSC warning and the existence of the Caddell lawsuit do not automatically establish liability in another case. Product identity, defect evidence, causation, injuries, damages, and governing law must be evaluated individually.
Do I Qualify?
- Did you purchase or use Meisinuo Heated Insoles sold through Amazon.com?
- Did the insoles overheat, smoke, explode, ignite, or catch fire?
- Did the incident cause burns, medical treatment, smoke exposure, or documented property damage?
- Do you have the insoles, remote control, charger, Amazon records, photographs, medical records, or damaged property?
An individualized legal review can determine whether the product, battery failure, injuries, damages, available evidence, and applicable filing deadlines support a potential claim.
What Evidence Should I Preserve?
Preserve photographs of the insoles, heel area, remote control, charger, cable, packaging, labels, and visible fire or burn damage when this can be done safely.
Save Amazon order histories, receipts, listing screenshots, seller communications, photographs, videos, damaged footwear, medical records, fire reports, and insurance documentation.
Do not intentionally recharge, test, puncture, open, or disassemble an insole after a thermal incident.
How Should Meisinuo Heated Insoles Be Disposed Of?
CPSC warns consumers not to put the defective lithium-ion battery products in household trash, curbside recycling, general recycling streams, or ordinary retail battery-collection boxes.
Consumers should contact a municipal household hazardous-waste facility before bringing the insoles there and confirm that the location accepts defective lithium-ion devices.
EPA likewise advises that lithium-ion batteries and devices containing them should not go in household garbage or municipal recycling because they can create fires during collection, transport, or processing [4]
Why Evidence Preservation Matters Before Disposal
CPSC advises consumers to dispose of the defective products, but an injured consumer may also need evidence establishing product identity and the condition of the insole after an incident.
Before disposal, photograph the product from multiple angles, including the heel area, charging components, burned or melted material, footwear, and surrounding scene when safe.
Digital records should be retained even if the physical product ultimately must be surrendered or discarded for safety reasons.
