I have a pair of Keen commuter bike shoes (they are more like sandals, but they protect the toes). The nice thing about these shoes is they are a US size. I usually wear a size 6 1/2 to a 7 in a US size. I know bike shoes usually run small (at least for me). I was thinking along that line when I purchased the Keen commuter bike shoes - I ordered them in a size 7 1/2. I have found they run true to US size. I should have ordered the size 7. I love these shoes, they are so comfortable and they do have the ability to use clips.
