Detailed description

Working in a cold environment or outdoors during the winter months requires extra protection for the feet against the thermal risks of cold. For this reason, JLF Pro has created the Thermal insole, made of 100% natural wool, to provide effective protection and insulation from even the worst cold and damp.
The aluminium-covered film, the closed cell foam and the wool in contact with the foot provide immediate warmth and make this product very effective. This insulating shoe insole is the perfect accessory to warm the feet and improve comfort at work.
  • 100% natural wool felt in contact with the feet against cold
  • A closed-cell foam trapping the air
  • An aluminised anti-slip film reflecting the cold coming from the ground
