Like most people I obsessed and worried about buying boots online because of the sizing problems - both in foot size and calf circumference. I read every review I could find on these boots and finally decided to go with my usual size which was European 42 or 11, and this was perfect. In retrospect on Amazons sizing chart 11 is 41-42 and 11 and a half is 42, so I guess I did order half a size down. The boots are everything I expected and more; the colour (gaucho) is great, they were comfortable from the moment I put them on, they were easy to get into, they were not too heavy. In short I am completely sold on Frye boots and am looking for my next pair already. Am drawn to the Harness 15R and some very helpful reviews say that this is a wide fitting boot and so hopefully the calf circumference won't be too tight, which is my usual problem in boots.
