I know it is a little steep but I camp and work outside a lot and there are days where
i would pay anything to be able to work with out cold feet.
maybe its i'm getting to old or have froze my feet to many times to were my feet hurt that i could really use something like this some days.
last year i remember camping with the boy scouts were it was a high of 10 degrees
for 3 days. it was so cold the propane didn't burn right and we had vegatable oil freeze. My feet took a beating that week end
