I really like these boots but I ordered an 8.5 which I usually wear and sent it back for a 9.  The calf in the 8.5 fit snug but on the 9 one was tighter than the other...almost too tight which I think is a manufacturing flaw.  I'm considering returning them as well.  I really want to keep them as a friend got them and hiked all over Iceland in them.  Said they were sooo comfortable, did not need breaking in and were easy to clean because they are water resistant...just hose them off.  I bought my college daughter a pair for cold weather trekking in the rain and dry on campus.  The top of the boot does not come up as high as a normal riding boot style which is good for me because I am short.
