Popular Running Shoe Comparisons
The ASICS S4+ YOGIRI and On Cloudboom Max are both racing shoes geared toward 4-hour marathoners, but each makes slightly different adjustments that move them from the front to the middle of the pack. The S4+ YOGIRI still has a very rigid carbon plate and the streamlined profile of a top-tier racing shoe, but a less pronounced rocker. The Cloudboom Max, meanwhile, features an aggressive rocker, a plastic-plated midsole, and a very wide base that adds stability but also considerable extra weight. For intermediate marathoners who are concerned about their form or worried about instability, the Cloudboom Max is the more solid option. For marathoners who are confident in their form and want the relatively lightweight feel of a super shoe, the S4+ YOGIRI is a livelier option for achieving a sub-4-hour finish.
