BERGAL Thermo Soft - super light, odour-inhibiting and wonderfully warming insole for cold days. For the first time, the functional fibre PrimaLoft is processed in a sole. The innovative material is particularly used in winter jackets and gloves and has similar properties to the natural down fibre. The high-tech fibre PrimaLoft Gold Eco is made from 90% recycled polyester and is bluesign certified. It has excellent heat output and stores up to 38% of body heat in the shoe. In addition to this unique material, a cuddly soft outer material ensures pleasant first comfort. While the memory latex comfortably cushions the sole, the incorporated activated carbon absorbs and neutralises foot odour. The aluminium layer also insulates against the cold from below. Finally, a thin grip latex protects the sole from slipping in the shoe and thus ensures a firm stand. Thanks to the non-bulky height of the Thermo Soft winter insole, it can be worn in everyday shoes in the transitional period as well as in the winter time as well as during sporting activities.
