Great, lightweight racing shoe. I didn't give it 5 stars because they are a little difficult to get on for transitioning from bike to run. Only a big deal if you're using them for triathlons. The back of shoe is too rigid. The BOA lacing system is awesome. The shoe seems to run a bit narrow which works well for my foot. As previous comments suggest, order 1/2 size up. I typically wear size 11, and 11.5 fits perfect.
