Meisinuo Heated Insoles Lawsuit Update: Injuries, Recall Status, and Legal Options

CPSC warns that Meisinuo Heated Insoles, sold on Amazon.com, pose a risk of serious burn injury and fire. It told consumers on July 9, 2026 to stop using them. On December 3, 2025, one plaintiff sued Amazon and Meisinuo over these insoles in federal court in Oklahoma. The case is Caddell v. Amazon.Com Inc. She alleges the insoles exploded and burned her feet. No MDL or class action has been formed. CPSC issued a warning rather than a recall. The newest court order, from May 11, 2026, deals only with service on Meisinuo.

Latest Meisinuo Heated Insoles Lawsuit Updates

July 9, 2026: CPSC Issues Warning on Meisinuo Heated Insoles

CPSC issued Product Safety Warning #26-612 and told consumers to stop using Meisinuo Heated Insoles [1]. It knows of 17 reports of fires, explosions and other thermal incidents, with at least 15 reported burn injuries. The warning covers about 1,372 units. CPSC says the internal lithium-ion battery can explode and ignite. The manufacturer has been unresponsive to CPSC requests for a recall or information about this product.

May 11, 2026: Court Finds No Good Cause for Delay in Serving Meisinuo

The Western District of Oklahoma court found no good cause for the plaintiff’s failure to serve Meisinuo [2]. She made no attempt to serve it and chose to delay while seeking early resolution with Amazon. The court allowed 90 days from the order to serve Meisinuo. Absent proof of service or a changed procedural posture, the claims against Meisinuo will be dismissed without prejudice.

April 21, 2026: Court Orders Plaintiff to Show Cause on Service

The court ordered the plaintiff to show cause why the case should not be dismissed without prejudice [3]. The reason was failure to serve Meisinuo within 90 days after the case was filed. The order cited Federal Rule of Civil Procedure 4(m). It is docket entry 10 in the case before Judge Timothy D. DeGiusti.

December 3, 2025: Complaint Filed Against Amazon and Meisinuo

The complaint was filed in the Western District of Oklahoma against Amazon.com, Inc. and Meisinuo [4]. The plaintiff alleges heated insoles bought on Amazon exploded, caught fire and burned her feet. These are only the plaintiff’s allegations. The court has made no finding on liability, and its rulings so far deal only with service on Meisinuo.

Who May Be Affected?

The CPSC warning covers black, remote-controlled Meisinuo Heated Insoles. Amazon.com sold them from August 2023 through December 2024 for $35 to $90. Each pair has a lithium-ion battery in the heel area. The name “Meisinuo” is printed on the product or appears on the purchase receipt. Fires, explosions and burns while using these insoles are the events the warning and the lawsuit describe. Whether you have a claim depends on your own facts, and only an individual legal review of your situation can say.

Reported Injuries or Damages

The CPSC warning describes serious second- and third-degree burns requiring hospital treatment. MedlinePlus says second-degree burns damage the outer layer of skin and the layer below it [5]. The reports do not prove the insoles caused every injury. The complaint says the fire started a couple of steps after the plaintiff put on laced boots. She alleges she needed immediate medical treatment. CPSC explains how lithium-ion batteries fail in a Federal Register rulemaking on micromobility products [6]. An overheated cell can start a self-sustaining reaction called thermal runaway. That rulemaking does not name heated insoles.

Recall and Regulatory Background

CPSC’s action is a safety warning and not a recall, so no refund or replacement program exists. A warning does not establish liability for any injury. See our heated insoles warnings page for more on CPSC actions.

Evidence to Preserve

Keep these items:

• The remote, the charger and the charging cable.
• The original packaging and the Amazon order confirmation or receipt showing the Meisinuo name.
• Photographs of the insoles, the boots or socks, and any burns.
• Medical records and bills for any treatment after a fire, explosion or burn.
• Any messages with Amazon or the seller about the insoles or the incident.

Take the photographs first. Then take the insoles to a municipal household hazardous waste collection center, as CPSC directs. EPA also says lithium-ion batteries should not go in household garbage or recycling bins [7].

Filing Deadlines

Deadlines to file a claim over a product injury come from state law. These deadlines depend on where you live and when the injury happened. A claim with strong facts can still be lost once its filing deadline passes. Talk to a lawyer promptly about the time limits that apply to you.

Potential Compensation

The Caddell complaint pleads damages for medical expenses, pain and suffering, emotional distress and possible permanent injury to the plaintiff’s feet. Compensation amounts vary by case. Past results do not guarantee future outcomes. Potential compensation in the Caddell case depends on a court ruling or a settlement.
