Our Take 

The CloudRunner still fits a relatively neutral foot but has some added support elements that make it a more stable option when compared to the CloudGo and CloudSurfer without sacrificing the cushioned feel that On is known for.  This is done by adding a bit of width to the platform of the shoe and using a slightly wider Speedboard combined with a foot cradling design that supports the foot on every footstrike.
