Built with active, frigid outdoor work days in mind, these men's winter boots combine the agility of a light hiker with the warmth of a down jacket. The waterproof, breathable KEEN.DRY membrane lets vapor out without letting moisture in. Lightweight, extremely compressible KEEN.WARM insulation retains its heat-trapping power, even when damp. The compression-molded EVA midsole delivers cozy cushioning for all-day comfort, and the KEEN.Polar Traction outsole provides great grip where others slip ... even on inclines!
