I've been using the Asolo TPS 520 boot for about 3 years now. They're a park builders dream boot. Great traction either on dirt, snow or even ice. Extremely durable (I've been on the same boot for 3 years now), and crazy waterproof (Standing in wet spring slush for 8 hours and still having dry socks is pretty rare with other boots, these will keep your feet warm and dry). I use them for hiking, building, and even setting up during urban missions. They're pretty much the best boot I've ever used.
