I bought these shoes for my boyfriend. This is his second pair. They are a very good MTN bike shoe. They are great for narrow feet. If you have really wide feet, They are not the shoe you are looking for. He wears between a 10.5 and 11 US shoe and I bought the 45.5 and they fit great. The only issue he has had is that, over time, the plastic mount, where the pedal clips in, wears down and it gets a little bit of play. Also, if you are walking a lot up hill off your
bike you will peel off the material on the toe. It doesn't affect the function of the shoe, it just looks bad. Ride on!!!!
