I was first attracted to these shoes for their very lightweight, lower drop foundation that gives a supportive feeling while not being too overbearing. In terms of running performance, the Cloudflows did not disappoint. I’ve been able to increase my weekly mileage with alternating terrains, and the shoes have kept me feeling strong and injury-free. When it came time to purchase a new pair of running shoes, I stuck with the newer version of the Cloudflows. I have to agree, however with a few other reviews. In the next generation, I figured some of the earlier kinks would have been ironed out, but I’ve still had issues with keeping the laces of my shoes tied tightly. They seem to loosen very quickly, almost immediately after tying. Secondly, the interior of both pairs of shoes has worn down rather quickly. I always untie my laces when putting on my shoes, but the areas around my heels have worn through the fabric and exposed the foam below. It happened after a few months with my first pair, and the same is beginning to happen with my next. All in all, solid running shoes though. Definitely recommend.
