They provide remarkable insulation, keeping my feet toasty during the coldest, snowiest, and wettest winter days, ensuring comfort even during extended outdoor activities.Traction: The traction on these boots is nothing short of phenomenal. I've found myself leaving my traction cleats in my pack for all but the most treacherous icy trails. They've allowed me to confidently tackle varied winter terrains without slipping, which is crucial for both safety and enjoyment outdoors.Waterproofing: I've encountered no issues with water ingress during incidental shallow stream crossings, confirming their waterproof claims. The boots have successfully kept my feet dry in wet conditions, enhancing their utility in diverse winter environments.Versatility: They are not only comfortable for walking but also fit snowshoes perfectly when needed, making them a versatile choice for different winter activities.In summary, after a year of testing these boots in the coldest, wettest, and most demanding conditions, I can wholeheartedly recommend the KEEN Men's Revel 4 Mid Height Polar Insulated Waterproof Snow Boots.
