I have a unique challenge for footwear that I need to resolve before late august. I will be working as a hunting guide in the Mackenzie Mountains of the Northwest Territories starting around this time. Conditions will be variable, but may frequently dip to -15C. There will be long days afoot with rough ground and even some muskeg, and also frequently packing heavy (100+lb) loads, but also long periods of inactivity where frostbite would be a major concern. These are remote conditions, without a real base camp to rely on for up to 5 days. Obviously, having the right footwear is imperative.
So, what to wear? I am leaning towards either adventure racing shoes or hiking boots with layered socks and a layer of Gore-Tex socks, and carrying a pair of insulated overboots for the inactive times. I would prefer the shoes for walking long distances, but, even though I discount most of the hype about ankle support, these are extreme circumstances. As for overboots, the only ones I have found that seem appropriate are those made by Wiggy’s (http://www.wiggys.com/moreinfo.cfm?Product_ID=43), but I would be interested in other options.
I would appreciate for any thoughts or advice.
