This shoe has many great features but the best one for me is the sole - it has a carbon section that is not like many road shoes. This carbon piece does not extend for the entire sole of the shoe
The carbon piece is positioned under the cleat mounting section to distribute the load from the cleat/pedal interface. Many mountain bike cleats are small and the load can get concentrated under a small portion of your forefoot. With this one , it gets spread over a larger area and reduces the risk of having a sore foot.
Why is the carbon piece smaller? It is so that you can not walk like Frankenstein when you are off the bike. The rubber that makes up the midsole is great because it provides some cushion, but it is not too soft - it is just right :) You can walk around easily and it also provides stiffness on the bike - ingenious.
The heel cup retains your foot while riding as well. Probably the best feature of this shoe is the dual BOA enclosure. With the two of them, you can adjust the fit to just how you need it at any point in the ride. Too tight? Rotate the dials to loosen - no need to pop them back up, they are bidirectional. You just have to remember that the dial on the left is backwards of the one on the right :)
I do not mean to sound like a shill, I am just thrilled with this shoe. I moved from a pair that was not that stiff in the forefoot and it resulted in some sore feet. Those shoes also had traditional strap and ratchet enclosures.
This is a great shoe. Any downside? Maybe the lack of airflow, but that is a personal preference and with a mountain shoe - it is a tradeoff with getting water and trail/road debris in the shoe.
Two thumbs up for this shoe!
