Mens Constrictor IceGrip Warm GTX, Winterboots, Black

The Constrictor IceGrip Warm GTX: In order to guarantee dry and warm feet in the cold season, Viking has consistently relied on the market-leading waterproofness of a GORE-TEX membrane. The Constrictor IceGrip Warm GTX also features the most advanced cold-weather grip system without spikes to date: Vibram Arctic Grip, which combines specially developed rubber technology with large-scale lugs to offer excellent grip on icy surfaces.

The outsole is combined with a comfortable and lightweight EVA midsole that provides shock absorption and a heat-reflective sockliner that provides insulating protection against the cold ground beneath. That's not the end of the isolation story, however. The Constrictor IceGrip Warm GTX also has the first-class PrimaLoft Gold insulation, which offers warm insulation even after repeated compression.

The PrimaLoft insulation is also Bluesign and Oeko-Tex Standard 100 certified, and made from 100% Global Recycled Standard (GRS) certified recycled materials.
