Once the leaf-lookers clear out and the fall litter that covers the trails is blanketed with several feet of snow, pull on a pair of Keen Men's Durand Polar Boots and enjoy the solitude only mid-winter mountains can deliver. The Durands are made in America and heavily insulated with KEEN. Warm synthetic insulation for serious warmth. Their waterproof, breathable insert prevents heat-robbing moisture from creeping through as you break trail through the fresh snow. Underfoot is a heat-trapping footbed to prevent heat loss through the sole of the boot. A cushioning PU midsole with stability shank ensures stability and comfort when the snow turns to compacted ice. Their sole is made from a multi-density rubber with an aggressive tread pattern to keep you on your feet on all but the iciest surfaces.
