Ok. The shoes are very cool - in both senses of that word. And if they fit, I suspect they would be very comforable. But the sizing business is utterly ridiculous. I wear a European 44. In some shoes (including my first KEEN shoes, a 43 is a better fit. I read the warnings that they run small, and took the advice to go up a half size. I ordered 45, and they fit like sausage casings and cut off circulation.  I suspect that even 46 might be too snug. NB; This is not just  a question of width. The 45s are barely long enough. If you are able to send shoes back and forth until you get the right fit, then go for it. These are a great design. (I live overseas, so can't swap until I get my size.) KEEN should really work out the true measurement of each of the UNEEK sizes and sell people the size they need. Throw a note int he box to tell people to ignore the size printed on the shoes.
