I used this shoe to do my steady miles in the build to the Toronto Marathon. What surprised me was the combination of cushioning and weight. This has been achieved by using a lightweight but very strong upper.

The first pair did 800 miles before losing their cushioning (more than I usually get) and the second pair are still going.

Good off road grip and space for my orthotics. So nothing really to complain about. A good everyday shoe.

Comfortable ride and some medial support makes this a good choice for longer races. Take care on the sizing.
