Safety and Benefits of our Thermrup Heated Insoles

Recently, media reports about heated insoles with integrated batteries have raised concerns about the safety of such products. As the market leader for heated insoles, we, Thermrup, would like to take this opportunity to clarify and show you the advantages of our Thermrup heated insoles with external battery.

Why are reports on heated insoles with integrated batteries critical?

In a recent report by ARD Marktcheck, warnings were issued about the risks of heated insoles with an integrated battery. The main problems with these models are:

• Mechanical stress: When walking, you stand and walk directly on the battery. This creates permanent pressure, which can lead to damage and, in the worst case, a fire risk.

• Limited lifespan: The battery is permanently installed and cannot be replaced. As soon as its performance decreases, the entire heated insole becomes unusable.

• Increased failure rate: Due to the limited height available in the sole, both the battery and the control board must be accommodated in a very small space. This leads to a higher susceptibility to defects.

However, these problems concern only heated insoles with an integrated battery – and not our Thermrup heated insoles with an external battery!

Advantages of our Thermrup heated insoles:

Maximum safety – No direct pressure on the battery, therefore no risk from mechanical damage or overheating.

Long lifespan – The battery is replaceable, so the heated insoles can be used for years.
High wearing comfort – Thanks to the external battery, the sole remains thin and flexible.
Easy handling – The battery can be conveniently attached to the calf or the shaft of the shoe.
