This is late to the party but - I use boots for walking only in extreme cold and then I must say I am less and less inclined to walk . But in normal nasty cold, I find they're feet get cold enough to lift and limp when we first start out. If I just give them a quick warm up with my mitt and then a quick pace for the next bit to get the blood flowing, then they are usually fine. My Jack never needed boots in any weather but I find these two are less hardy souls
