Light weight shoe with great materials and flawless workmanship. I really like the sleek styling. The fastening system is quick and easy to use, providing an excellent customizable fit. Sizing is true. I'm a US size 12 and fit well into the EU 47. Cleat mounting was super-simple. The shoe overall is not as well-vented as others I've worn. It's great on cool mornings, but when the temperature gets into the 80's, my dogs are toasted. If your feet run cold, this is a great choice. If you cycle in warm climates, maybe not so much.
I'm pretty picky with shoes, and these are pretty solid. I really appreciate the extra toe box room and comfort for what otherwise feels and performs like a top-shelf racing shoe. The downsides are that they're a little pricey for a single-Boa shoe, and that the dial's positioning initially places pressure on the top of your foot (this goes away once broken in, but it was almost a dealbreaker initially).
