The patented ultrathin insulation surrounds foot fingers only, the most sensitive to cold. It keeps your feet much warmer outside up to 7 times more than a traditional loft insulation, but your feet are not overheated when you are in a closed room, offering comfort all day long.

The GORE-TEX INFINIUMTM THERMIUMTM revolutionary technology used by FRAU does not change shoe appearance but it insinuates itself silent and invisible ensuring heat without giving up glamour and the quality of a 100% Made in Italy product.
