I had to order two different sizes as my left foot is swollen right now from a broken leg. It worked! They are very comfortable, keep my feet warm in this cooler weather, and keep my feet dry! I am really happy how nice they turned out! And when I get both my feet the same size again, I will have 2 pairs to wear with different size socks for different weather. When you have a good shoe, it is great to have 2 pairs!!!
