thinking about getting a pair of ON running shoes. Anyone know what the difference is between the cloud runner and cloudsurfer? I've been reading up on them and it seems like the pods were designed for a certain pace n mind. The company website has certain running paces for each shoe so does that mean you won't get the full cushioned benefits of the shoe unless you stay in that pace range? I want maximum cushion but my pace probably fits the cloudsurfer.
