Be Lenka ThermoWool Insole – Cacles Barefoot

Meta Description (SEO):

Be Lenka ThermoWool replacement insole with merino wool, carbon, and aluminum for cold insulation. Compatible with Be Lenka footwear, 5 mm thickness.

Be Lenka ThermoWool Insole – Four technical layers to insulate against the cold in your barefoot footwear

At Cacles Barefoot, you will find the Be Lenka ThermoWool replacement insole (ref. 90050276), designed for cold days. It combines a top layer of natural Merino wool with three additional technical layers that block cold from the sole, maintaining a 5 mm thickness that does not compromise the natural sensitivity of barefoot footwear.

Why choose the Be Lenka ThermoWool Insole?

  • Thermal insulation with Merino wool: The top layer, made of 100% natural Merino wool, offers outstanding thermal insulation and a soft feel against the foot.
  • Natural resistance to microbes and mold: Merino wool has natural properties that resist the proliferation of microbes and mold, without the need for added treatments.
  • Four-layer structure: Beneath the Merino wool are a CARBON latex layer, an aluminum (ALU) sheet, and a perforated latex foam layer, which together effectively block the cold.
  • Anti-slip effect: The perforated latex foam on the bottom layer provides stability and comfort, as well as preventing slipping inside the shoe.
  • Reduced 5 mm thickness: A thickness designed to replace the original insole without excessively altering the fit of the footwear.
  • Wide compatibility: Suitable for all Be Lenka adult footwear, except for models with AlldayComfort soles, such as loafers and ballet flats.

Benefits of the barefoot design

  • Zero drop: The absence of a drop between the heel and the toe favors a more natural stride and a more aligned body posture.
  • Wide toe box: Allows the toes to move freely and distribute weight better with each step.
  • Sole flexibility: A flexible sole respects the natural movement of the foot rather than restricting it.
  • Increased proprioception: By reducing excessive cushioning, the foot better perceives the terrain it walks on.

Cleaning and maintenance tips

  • Clean the Merino wool layer by hand, with warm water and a mild soap, without rubbing excessively so as not to damage the fiber.
  • Always let the insole air dry away from direct heat sources, avoiding radiators or dryers, so as not to deform the latex and aluminum layers.
  • Do not submerge it completely in water for long periods, as the ALU sheet and CARBON latex are technical layers not designed for prolonged immersion.
  • Air out the insole regularly to take advantage of the natural resistance of Merino wool to microbes and odors.

At Cacles Barefoot, you can find this Be Lenka ThermoWool insole to add extra warmth to your barefoot footwear during the winter.
