I ordered these and could not fault the comfort when trying them indoors. I have wide feet and bunions, they make my feet look strangely normal. But we have a gravel drive and lots of rough terrain, so I didn't think the soles looked very practical. I ended up ordering the Cloudventure which are also super comfortable, and have no stone collecting grooves on the soles. But the Cloudventure shoes are waterproof, hence a bit hotter in the summer, so I couldn't bring myself to part with the OnClouds! They are superbly comfortable, and so light, they are ok for very hot weather as the upper is just a fine mesh. And in fact the stone collecting issue is not so bad, I have a metal tool on my key chain that I sometimes use to remove bits of stone. I love both my pairs of Cloud trainers.
