Men’s insulated foil insert FM (-30°C)

The insert is made of a multi-layer sandwich, which works to protect against the cold, preserve body heat, remove moisture and facilitate movement.
Foil cloth reflects the cold outside. It creates the effect of a thermos and allows you to maintain a comfortable temperature. Holes in the foil contribute to the removal of moisture from the liners.
The non-woven cloth keeps the feet warm.
Soft fur with the addition of 30% natural wool warms and adds a feeling of comfort.
The heel insert is externally reinforced with dense, smooth fabric.
The edges are trimmed with a special strong tape.
