Pros: I love vivo shoes and have a pair of Breatho trails that I wear whenever I can. I got these for gardening and dog walking on hot days when you need something more stable than thongs but just as cool. These are good for both those activities.
Cons: I've worn these on the beach and they're not great water shoes because the drainage holes are all on the top of the shoe. This means that once you've stepped in water, an inch of water stays sitting in the bottom of the shoe. The holes also let a lot of sand a grit in which can be very uncomfortable.

I've edited this review and changed it from 4 to 5 stars. They're still not good beach shoes but I've been using them for almost everything else through the Australian Summer - running, gym, etc - and I love them. I'm wearing them even more that my vivo brethos. They lose points for fashion because they look like crocks but they're the most comfortable summer shoes ever. I often wear them with ordinary cotton sports socks unless it's very hot.
