Built for wet, cold conditions, these men's hiking boots feature a Primeknit sock-like design inside a waterproof, insulated upper. They stretch and conform to your foot for extended comfort. An external sleeve zips up to help seal out the elements. The Boost midsole provides long-lasting cushioning that doesn't stiffen up in the cold. A Continental WinterGrip rubber outsole provides winter-specific traction on snow and ice.
