I initially ordered size 10, and they were way, way, WAY too long. Then I noticed that the tag said EU 42, which is actually US size 11. That made sense, because they fit like 11's. I considered the 9 wide but was worried that it would be sloppy around the heel and potentially too short in the toe box, so I ordered the 9-1/2 and it's a perfect 41. They are still a little long in the toe but I am happy with that as I usually have trouble with not enough toe room on the left. I have long narrow feet and long toes, and these are a perfect fit, and very very comfortable. Timberland seems to be one of the few bootmakers, along with El Naturalista, who does not assume that large feet means giant ankles. The leather is gorgeous and feels wonderful. These are a perfect match for my winter obsession with short sweater dresses and long leg-warmers!
