I'm supper picky when it comes to boots/shoes, but these are perfect! I was looking for an "easy on" boot, witch these are, slip on and zip up! I was looking for something to keep my feet warm (I live in NH and we get lots of snow and cold weather), these are so awesome. My feet are always cold, even inside. but I put these on in my house to walk around to see if I liked them and my feet got warm in them...something not even my slippers do (lol). I only wear ultra thin socks, that being said my feet still stay warm in these, but for someone who wears thicker socks might need a larger boot then what they normally would. A bit bulky but its not that bad. I feel like I am tall in them because the sole is thick witch keeps you way from the snow! Just so very happy with them, well worth the money!
