The CPSC warns that COOWALK and COOWALI heated insoles can explode and ignite while switched off. Their lithium-ion battery sits in the heel of each insole. One federal complaint alleges an insole burst into flames and caused severe burns. On June 4, 2026, the CPSC issued a stop-use warning. It is not a recall. The complaint, Monnier v. Amazon.com, Inc., was filed in federal court in Colorado on December 29, 2025. The case is individual. No class action, MDL or settlement names these insoles. If you own a pair, stop using them right away and follow the CPSC disposal steps.

June 4, 2026: CPSC Warns Consumers to Stop Using the Insoles

The CPSC warned consumers to stop using COOWALK and COOWALI heated insoles immediately. The warning says the lithium-ion battery can explode and ignite, even when the insoles are turned off [1]. The CPSC cites about 6,000 units. It has 26 reports of fires, explosions and other thermal incidents, with at least 23 reported burn injuries. The CPSC adds that the maker has been unresponsive to its recall requests.

December 29, 2025: Complaint Filed Against Amazon and Shenzhen Companies

A federal complaint was filed in the U.S. District Court for the District of Colorado. It names three Amazon entities and three Shenzhen companies. The case is Monnier v. Amazon.com, Inc., No. 1:25-cv-04194 [2]. The complaint lists five counts. Three are strict products liability claims for design defect, failure to warn and manufacturing defect. The other two are negligence and negligent undertaking.

Who May Be Affected?

The people most directly affected bought or used black or red heated insoles. Each has “COOWALK” or “COOWALI” printed on the sole, a lithium-ion battery in the heel and a remote control. The CPSC says they were sold on Amazon.com and GearTrade.com from August 2022 through May 2026. People whose insole caught fire, exploded or overheated, including while turned off, are also affected. So are people who were burned or had property damaged. Whether your facts support a claim depends on an individual legal review.

Reported Injuries or Damages

The complaint alleges that an insole overheated and burst into flames inside a boot on February 10, 2024. It alleges severe burns to the outer right foot [3]. It also alleges an Integra skin graft on or about July 10, 2025. A split-thickness skin graft followed on or about August 7, 2025, with prolonged physical therapy. The CPSC warning also describes serious second- and third-degree burns requiring skin grafts. Its reports do not prove that an insole caused each injury. The CPSC’s lithium-ion battery rulemaking explains thermal runaway. An overheating cell can ignite its flammable electrolyte [4]. The proposal covers micromobility products only. MedlinePlus says third-degree burns damage or destroy the deepest layer of skin and tissues underneath. Burns can lead to infections [5].

Recall and Regulatory Background

The CPSC issued a Product Safety Warning for these insoles. It is not a recall. The manufacturer is Shenzhen Kubuzhineng Kejiyouxiangongsi of China. For recalls of other heated insoles, see our heated insoles recall page.

Evidence to Preserve

Keep records that show which insole you had and what happened to you:
  • Product marks: “COOWALK” or “COOWALI” on the sole, the color and the listing name.
  • Purchase records: the Amazon.com or GearTrade.com order, the receipt and seller messages.
  • Photos of the insole, the boot or sock, the burn and any damaged property, taken before disposal.
  • Medical records and bills: hospital, wound care, surgery and therapy records, plus prescriptions.
  • Report copies: a SaferProducts.gov report number or any messages with the CPSC.
The CPSC says not to put the defective battery in the trash, the recycling or store battery boxes. Call your household hazardous waste center and ask if it takes defective batteries. The EPA guidance says lithium-ion batteries can cause fires during transport or at landfills and recyclers. It adds that devices containing them should stay out of household garbage and recycling bins [6].

Filing Deadlines

State law sets the deadline to file an injury claim, and it depends on where you live. Dates can also depend on when the injury and the burn diagnosis happened. Waiting too long can end a claim even when the facts are strong. If you were burned, speak with a lawyer promptly.

Potential Compensation

A burn claim over a heated insole may involve several kinds of damages, including emergency and hospital care, burn and wound treatment, surgery, skin grafting and follow-up care. A burn claim could also involve medication, physical therapy, future medical needs, lost income, pain and suffering, emotional distress, scarring and property damage. Compensation amounts vary by case. Past results do not guarantee future outcomes. Potential compensation in the complaint includes compensatory and punitive damages, along with a jury trial.

Frequently Asked Questions

Is There a COOWALI Heated Insoles Lawsuit?

Yes, one federal complaint over a CooWalk heated insole was filed on December 29, 2025. The CPSC warning covers COOWALK and COOWALI together, and Magistrate Judge N. Reid Neureiter was assigned to the lawsuit.

Did CPSC Recall COOWALI Heated Insoles?

No, the CPSC did not recall COOWALI heated insoles. It issued Product Safety Warning 26-533 instead of a recall notice. No recall number, refund or replacement program has been announced for the insoles.

Does the CooWalk Heated Insoles Complaint Say Amazon Knew of Earlier Incidents?

The CooWalk heated insoles complaint alleges Amazon had actual knowledge of earlier safety incidents. It names the Chinese companies out of an abundance of caution and alleges they are not subject to U.S. jurisdiction.

How Can Heated Insoles Catch Fire?

Heated insoles with lithium-ion batteries may catch fire through a general battery mechanism, which a CPSC proposal on micromobility products describes. An overheating cell builds pressure that can expel hot gases, burning cell materials and flames. That is not a finding about these insoles.

What Does the Research Say About COOWALI Heated Insoles?

The CPSC warning is the main research on COOWALI heated insoles. It counts 26 reports, at least 23 of them involving burn injuries. The reports do not settle what caused each burn.

Where Can I Report a Heated Insole Burn?

Report a heated insole burn or defect to the CPSC at SaferProducts.gov. You can also call the CPSC hotline at 800-638-2772 (TTY 800-638-8270), open 8 a.m. to 5:30 p.m. ET.
