Incident Overview

On February 5, 2026, an incident was reported involving a Metas No Unknown heated insole. According to the report, the insole caught fire. Crucially, the product was not turned on at the time of the fire. The incident resulted in severe burning to the foot.

Safety Concerns

The incident with the Metas No Unknown heated insole presents serious safety concerns, primarily revolving around uncontrolled fire and burn hazards:

  • Immediate Dangers: The most immediate danger is the risk of severe thermal burns to the user. As evidenced by the report, these burns can be debilitating and require extensive medical attention.
  • Fire Hazard: A product catching fire, especially when not turned on, poses a significant risk of property damage. Such an event could easily escalate into a larger structural fire, endangering homes, vehicles, and other personal property.
  • Uncontrolled Ignition: The fact that the insole caught fire while *not* turned on indicates a failure mode that is not tied to active use, which means the product could pose a hazard even when stored or seemingly inactive.
  • Who Might Be Affected: Anyone owning or using Metas No Unknown heated insoles could be at risk. This includes individuals who rely on such products for warmth or therapeutic purposes.
  • Long-Term Risks: Severe burns can lead to lasting physical damage, including nerve damage, scarring, and chronic pain, requiring long-term medical care and potentially impacting quality of life.

What Consumers Should Do

Given the severity of this incident, consumers who own or have purchased Metas No Unknown heated insoles should take immediate action:

  • Immediately Cease Use: If you own a Metas No Unknown heated insole, discontinue its use immediately. Do not attempt to turn it on, charge it, or use it in any capacity.
  • Isolate the Product: Store the product in a safe, non-flammable location, away from combustible materials, until further guidance is provided.
  • Check for Ownership: Verify if the product you own is a Metas No Unknown heated insole from the manufacturer METASONO-US. Check packaging, instructions, or directly on the product itself.
  • Report Incidents: If you have experienced a similar incident, or if your product exhibits any signs of overheating, smoke, or unusual odors, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov.
