I've had these boots for a few months now and LOVE them.  Unintentionally, I've been wearing them as "winter boots" but they are not.  I have been lucky though,  b/c they keep my feet warm!  I normally wear a size 8 and purchased an 8, but they are a little big.  Could have probably gone with a 7.5.  All in all, I've been very happy with these boots!!!

PS, have not had any issues with the soles or zippers or anything.
