If you’ve been anywhere near a gym, an airport, or a city sidewalk lately, you’ve seen them. The distinctive perforated pods on the sole make on cloud shoes instantly recognizable. The Swiss brand On has taken the athletic and casual footwear world by storm, but with a lineup that includes the Cloud 5, Cloud 6, Cloudsurfer, and Cloudmonster, finding the right pair can be overwhelming. The truth is, while the brand promises a \"floating\" feeling, each model delivers that sensation in a completely different way. Some are designed for traveling through airports, while others are built to eat up marathon miles.
