The Be Lenka ThermoWool multilayer insole is an ideal solution for cold days. The top layer of natural merino wool provides excellent thermal insulation, is pleasant to the touch, and naturally resistant to microbes and mold. The lower layers (CARBON latex and ALU foil) effectively prevent cold from penetrating the shoe, and the perforated latex foam with anti-slip effect ensures stability and comfort. The insole is suitable for all Be Lenka adult shoes, except for models with an AlldayComfort sole (e.g., moccasins and ballet flats).Textile 100% natural Merino wool 4-layer material combination 100% natural Merino wool 100% CARBON latex ALU foil Perforated latex foam EAN/SKU: %eanorsku%
