Fit:
Im a size US 9 in New Balance and bought this shoe in a 42 and its a perfect fit. The toe box seems to fit me perfectly. Usually at 42 mtn bike race shoe is too narrow in the toe and doesnt fit well.

Heel:
My first time trying a pair on I didn't buy them due to my heel raising up a bit because of the spandex achilles dirt gator in a walking test. But these aren't walking shoes and cant be tested as such. Clipped into bike pedals they shine and I don't have any raising heel issues. The spandex gator keeps debris out very well! What I initially thought was a fault is one of my favorite features.

Laces/strap system:
Ive ridden clipped in Ive been riding with Boa shoes for years, these are my first laces/strap pair since 2004. I like it much better. I could never get the right tension with the Boa and the top wire loved to cut off circulation when too tight. These laces tighten snugly with a pull of the tab. The tab also has Velcro on it to connect to the outer laces cover to ensure it won't come out while riding. The laces cover gives you more protection on the top of your foot, which Im happy for (I have permanent scars there due to a thin shoe and a large branch incident)

Pros:
-very comfortable
-laces covered
-lace/strap system
-Achilles dirt gator
-Michelin sole
-large amount of clip adjustment
-highly breathable
-lightweight
-look awesome (black/blue)

Con:
-Heel fit seems weird until clipped in

Highly recommended
