I Love FRYE boots and went ahead to get myself my 2nd pair, this time in Tan color..the pair looks smart & the leather is tough, masculine and of good quality, however the zip is not as smooth as it should be and the size is wrong!! (which I hear is a problem being faced by other people who have got FRYE boots) although the size on the pair as well as on the site says US sizes..my pair fits tight. So I suggest, that for example if you buy a size 9 normally..please take this style in either size US 9.5 or go for a US 10 (i.e. If you plan to wear the boots with slightly thicker socks)
Hope someone at FRYE does something about this confusing size issue.
