Our Verdict
On Cloudmonster 2
On Cloudmonster 3
The On Cloudmonster 3 has several notable updates that set it apart from the On Cloudmonster 2. The upper of the third version has been reworked, and now has a bit more structure, so the fit is more snug and less baggy than the 2nd version. Underfoot, the two shoes have a similar configuration, with a plastic 'Speedboard' and pockmarked Helion foam, but the 3rd version is less firm and absorbs impact better.
