I've owned the Cloud for just under a year and run an average of 5-7 miles, 2-3 times a week. I have run a maximum of 24 miles in these shoes. I have a front to midfoot strike. Due to the type of sole it has, I restrict the terrain to roads and pavement (otherwise it picks up gravel, twigs, all sorts). First and lasting impressions are that it is extremely comfortable and feels almost weightless. The unique sole gives cushioned ride with a positive lift off. I've definitely enjoyed ticking the miles off in these. However, with my narrow feet I find the toe box a bit loose. I am used to this now, but there is a lack of lateral support when changing direction suddenly (even round a corner, for example). Because of that, I would not recommend these for general use (circuits / HIIT etc). However, for pure, uncomplicated road running these are a very good shoe.
