It's been cold here lately - aka: below freezing.  I've been wearing my boots outside and I'll be cold everywhere, except for my feet.  My feet have been so warm, they've been sweating in these boots, which is unusual for my feet.  The boots are very comfortable and have kept my feet dry through mud puddles and pouring down rain.  For sizing, I normally wear about a 9.5, but I ordered a 10 - I should have ordered a 9.5, I might have even been able to get away with a size 9.  The only problem with the boots, is that they are difficult to tie, with the laces tight enough, which part of the is problem is that they are slightly too big.  I love these boots though!  Great for wearing when checking on my chickens.
