I wear these as my casual/work shoe 24/7 (along with my lunas). If you're going to be putting in real miles, I would say proceed with caution. The Altra One2 is my bet for a great neutral trainer that you can blast away with on long runs, track workouts, and marathons. If you are very well adapted to barefoot running, then I would say go for vivos, but they are BAREFOOT shoes, so keep that in mind. Wonderful for daily life though. I usually get a new pair every year and wear them all the time till they fall apart. Amazon has good deals on them usually.
The Altra One2 is my favorite shoe right now as well Greg. Great minds think alike. I will continue to use those for all things running but thought the Vivobarefoots would make a great casual/walking around type shoe.
Most of my time is spent in other Vivos, Luna Sandals or VFFs. But for running, even hill sprints etc, I use the One2. I don't know many people who have success running volume in Vivos, though they certainly exist. Good for short runs to work on cadence and form though, for sure, though many options exist for that. I think if you're going to go barefoot you can actually do better than Vivos for running. And on that note, why not just go barefoot in the grass once a week for 20 minutes?
Hmmm, I have several ultras in Vivobarefoots. Switch between them and Topo Athletic for trails. Why caution?
Caution only in the sense that one needs to be smart about building up to the distances in minimalist footwear. I love it when I see folks out there doing marathons and beyond in Lunas, Skoras, and vivos. Just cautioning not to go from a cushioned shoe directly into running 50 miles barefoot overnight.
Could not agree more that folks who are not used to using their foot muscles correctly in the past need to transition slowly - the same with any muscle building and training transition.
