WINTHERM® SAFETY guarantees the insulation from cold using two technologies combined together.

INSULATION: the thin fibres of the felt keep the air inside the shoe guaranteeing the insulation
from cold environment thanks to the physical properties of the string, which is a poor conductor
of heat but a very good insulating material.

REFLECTANCE: the presence of a microfilm of aluminium inside the felt enables to maintain
its reflective properties: the heat generated by the foot is preserved inside the shoe.

The union of these two technologies enables to obtain a very high level of thermic insulation with a low
thickness of the felt and a subsequent reduction of the bulk inside the shoe.

Wintherm® antibacterial guarantees a very good transpiration and meets fully the requirements
of permeability and water vapor coefficient foreseen by the regulation UNI EN ISO 20345.
