I'm spending my first winter in SW Colorado and am so pleased with this boots. They are very comfy and warm, good arch support, great traction, and are water/snow-proof. I ended up ordering a 1/2 size larger to accommodate thick socks + sock liners. I definitely made the right decision there, as my normal size would have been too tight with the padded socks. I wear these with knee-high gaiters to hike in the deep snow, and just wore them with snowshoes for the first time. I was out for several hours with temperatures in the teens and came home with warm/dry feet. The laces are well-constructed too (a problem I've had with other hiking boots). This is my fourth pair of Keens, my first pair of their boots, and they definitely have a loyal customer here. Plus I got them a fantastic price!
