A good shoe for recovery runs. I suffered a broken tibia that required surgery / a plate and screws. It was a long recovery to get back to a decent pre-injury level and have to say that the Cloudsurfer was a big part of my recovery as it was my go-to shoe. It offers a very soft ride and great fit. I liked it so much that I included a pair of cloudflyer's and cloudcruiser into my rotation once I was able to introduce speed and distance to my training.
I still keep the Cloudsurfer in my rotation but definitely not a racing shoe as it is too heavy. Additionally, I tend to sweat alot during the hotter months so I had to limit these shoes to no more than 1 hour of running as the soles soaked up the perspiration like a sponge making them that much more heavier. In a perfect world, ON Running will make this shoe lighter and find a way to better dissipate the sweat that collects in the sponge-like material.
Overall, a solid shoe for recovery runs.
