I bought these boots because I wanted a really tall boot... for some reason a lot of "tall" boots only go mid calf while these go right under the knee.  They are light but hard to pull off - a side zipper would be nice in next years version.  I typically wear a 7 but went up to 7.5 to take into consideration thick winter socks - almost wish I went to an 8 because I tried these on without anything and my foot fit perfect - may be a little scrunched with a thick winter sock.
