I wasn't sure how I'd like the boots. I've had a pair of Danner Sharptail boots that are similar (back zipper) and I really like them. I got the Guidefitter deal with these Rocky boots and decided to try them out. First, they are more comfortable than my Danner's. Second, warm...and I mean they keep my feet warm all of the time. I did get cold feet in them yesterday, but it was during an ice fishing trip and I wanted to push their limits. Still, as an uninsulated boot...very nice. Lastly, they have a little slop in the top...but this is consisted with my Danner's as well...so be sure that you don't mind a little looseness around your calf. Around the foot (where you need it) they fit fine.
