REVIEW: On Cloudflyer - The New Black
Shoe manufacturers have been going the highly cushioned route. This one with its stiffer but just right feeling on the road gives the extra lift on hilly terrain.
You first notice the cutout on the center of the sole. On claims that this boosts performance. While I don't doubt that, it tends to catch small rocks into it but nothing of great concern.
The laces forego the traditional flat thread for an almost rounded one. I find that the laces do not come loose with this set up.
I would recommend this shoe for long runs.
