These are my first pair of "trendy" boots!  They are very comfortable but not very warm on your legs.  I expected too much I guess.  That said, the shoe portion is great and keep your feet very warm.  I believe they run true to size.  I wear a 7.5 and ordered the 7.  They fit snug at first but have stretched to accomodate my foot with heavy socks on.  All of that said, I really like these boots and would buy them again.
