COOWALK and COOWALI heated insoles have a lithium-ion battery that the U.S. Consumer Product Safety Commission says poses a risk of serious burn injury and fire. It covers about 6,000 units.
On June 4, 2026, CPSC told consumers to stop using the insoles immediately. A Colorado plaintiff has sued Amazon in federal court in Colorado, alleging the insoles burned her foot.
The Colorado case, filed in December 2025 against Amazon and three Shenzhen companies, is an individual claim. No class has been certified, no settlement has been announced, and no MDL has been formed.
Latest COOWALK Heated Insoles Lawsuit Updates
June 4, 2026: CPSC Warns Consumers to Stop Using the Insoles
The U.S. Consumer Product Safety Commission warned consumers on June 4, 2026 to stop using COOWALK/COOWALI heated insoles immediately. Warning No. 26-533 covers about 6,000 units sold through Amazon and GearTrade.com [1].
CPSC says the battery can explode and catch fire even when the insoles are off. It counts 26 reports of fires, explosions and other thermal incidents, with at least 23 reported burn injuries.
December 29, 2025: Monnier Files Burn Injury Complaint in Colorado
Monnier v. Amazon.com, Inc., 1:25-cv-04194, was filed in the U.S. District Court for the District of Colorado on December 29, 2025 [2].
Monnier alleges a COOWALK insole from Amazon ignited in her boot on February 10, 2024, and demands a jury trial.
Who May Be Affected?
You may be affected if you bought or used COOWALK or COOWALI heated insoles and suffered a burn or a fire from them.
The insoles are black or red, with a lithium-ion battery in the heel and a remote control. “COOWALK” or “COOWALI” is printed on the sole. They were sold between August 2022 and May 2026.
People who bought COOWALK insoles on Amazon, like the Colorado plaintiff, fit the product named in that case. Whether you can bring a claim depends on your facts, so only an individual legal review can say.
Reported Injuries or Damages
MedlinePlus explains that second-degree burns damage the outer layer of skin and the layer underneath, while third-degree burns destroy or damage the deepest layer [3]. CPSC’s reports, which are not court findings, include both.
The complaint alleges the insole melted and stuck to the plaintiff’s skin, causing severe burns to her outer right foot. It alleges hospital care on February 10, 2024, then wound care.
It alleges skin graft procedures on or about July 10, 2025 and August 7, 2025. The plaintiff also alleges ongoing pain, limited range of motion, weakness, gait impairment and a need for physical therapy.
CPSC’s June 24, 2026 Federal Register notice explains that a lithium-ion cell that overheats can start a self-sustaining reaction, called thermal runaway, that ignites the flammable electrolyte [4].
Recall and Regulatory Background
The CPSC action is a Product Safety Warning. It is not a recall. The Chinese manufacturer, Shenzhen Kubuzhineng Kejiyouxiangongsi, has not responded to CPSC requests for a recall or information about the insoles.
No recall, refund or replacement program is offered, and CPSC gives disposal guidance only. A warning is not a finding of liability. Other heated insole brands have drawn their own CPSC warnings: heated insoles recall warnings.
Evidence to Preserve
Keep these items, because they show what the product was and what happened to you:
- Photos of the insoles, the battery, your burn and any damage to your boot or sock, plus photos as the burn heals.
- The Amazon.com or GearTrade.com order and receipt, and any packaging showing the COOWALK or COOWALI name.
- Medical records, wound-care records and bills, from the first hospital visit to any later surgery or therapy.
- Messages with the seller or Amazon, including any complaint you sent about the insoles.
Filing Deadlines
Filing deadlines for a burn injury claim come from state law and depend on where you live and when you were hurt.
Missing a deadline can end a claim even when the facts are strong, so it helps to check with a lawyer promptly.
Potential Compensation
A claim over a burn injury could potentially cover medical and wound-care costs. It could also cover surgery, skin grafting, rehabilitation, lost income during recovery, pain and suffering, and scarring.
In the Colorado case, the complaint asks for compensatory damages, punitive damages, and interest and costs. That is the plaintiff’s request. It is not an award.
Compensation amounts vary by case. Past results do not guarantee future outcomes. Each person’s potential compensation depends on the facts.
Frequently Asked Questions
Is There a COOWALK Heated Insoles Lawsuit?
Yes, there is a COOWALK heated insoles lawsuit. One individual product-liability case names Amazon: Monnier v. Amazon.com, Inc. in Colorado, assigned to N. Reid Neureiter. The Colorado complaint also names three Shenzhen companies as defendants.
What Does the Monnier Complaint Allege About Amazon’s Knowledge?
The Monnier complaint alleges Amazon knew of earlier incidents. It says a consumer contacted Amazon from the hospital in December 2023 to report serious injuries from the heated insoles, and that the listing stayed available until at least November 2025. These are allegations, not findings.
How Can Heated Insoles Catch Fire?
Heated insoles can catch fire when a lithium-ion cell overheats. CPSC’s battery notice says heat from one failing cell may spread to other cells, and the results can include gas releases, explosions, burns and smoke inhalation.
How Do I Dispose of COOWALK or COOWALI Heated Insoles?
To dispose of COOWALK or COOWALI heated insoles, keep the battery out of the trash, general recycling and used-battery boxes. Call your household hazardous waste center first and ask if it takes defective lithium-ion batteries. If not, contact your municipality.
How Do I Report a COOWALK or COOWALI Heated Insoles Burn to CPSC?
To report a COOWALK or COOWALI heated insoles burn to CPSC, go to SaferProducts.gov. CPSC asks for reports of any incident involving injury or product defect. You can also call the CPSC hotline at 800-638-2772. For TTY, call 800-638-8270.
