COOWALK Heated Insoles Lawsuit Investigation

COOWALK and COOWALI heated insoles have a lithium-ion battery that can explode and ignite, even when turned off, says the U.S. Consumer Product Safety Commission. The agency has reports of serious burns. Some needed skin grafts. On June 4, 2026, CPSC told consumers to stop using the insoles immediately. One woman has sued Amazon and three Shenzhen companies in Colorado federal court. She alleges the insoles burned her foot. The case is an individual claim. Her docket is open with no certified class and no settlement, and no MDL has been formed.

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. Match your situation to these circumstances: a burn from the insoles, a fire or explosion in your boot, or treatment such as wound care or skin grafts. 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

CPSC says some reported burns were serious enough to need skin grafts. These are agency incident reports. They are not court findings. MedlinePlus explains that second-degree burns damage the outer layer of skin and the layer underneath [3]. Third-degree burns destroy or damage the deepest skin layer. CPSC’s reports include second- and third-degree burns. 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 thermal runaway. A lithium-ion cell that overheats can start a self-sustaining reaction that ignites the flammable electrolyte [4]. The notice covers micromobility products, not heated insoles.

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, and our heated insoles recall warnings page covers them in detail.

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.
