Awesome shoe. Got the white version and it looks sharp. The entire upper is of a smooth synthetic material and lightly padded. The both BOA dial assembly are in the perfect location. The upper cinches the upper portion of my feet really well and the lower one cinches the entire lower portion of my feet very securely. Just loved the way this shoe provides secure wrap around feel once BOAs are secured. For my size, the heel cup is very secure and comfortable. I love the rubberized heel padding and it is very comfortable.
The sole is very stiff. I have the RX8s and it was already stiff enough at the index of 10, this one is at 11. This is all out a racing shoe, very similar to the RX8s, but provides much better comfort for me.
I wear size 9.5 shoes with normal width and 42.5 fits me perfectly. With normal cycling socks, my big toe is just touching the front edge of the shoe. The width of my feet, especially near the ball of my feet fills out the side of the shoe.
Don't even think about it just go with it. Unless you don't want the best MTB shoe on the market.
