Asphalt eaters, light and quick!
The best way for me to see how good the Cloud are is to wear my previous pair of shoes and feel how much weight I don't have to carry anymore. The confort is great, it feels faster and my times are definitely proving it. Are my legs in better shape at the end of a run? Probably.
The only downside (hence the missing star) is it's inconvenient to run on surfaces other than asphalt or small gravel. Over a few weeks of running with it, I already had to stop a few times because I had a medium sized gravel rock stuck in. I am not really running on those surfaces but it happens that I have to cross areas where there are some. The street sides are also not exempt of those gravel rocks and I have to be careful to avoid them.
