I am obsessed with this shoe and only wish I lived closer to trails that warranted the FG sole! This is my second pair of Vivos and they are true to size, requiring no breaking-in which is such a relief. I think I'll be a barefoot runner for life.

Pretty Comfy

I've spent hundreds of dollars trying to find a shoe that would not hurt my feet, shins and calves. I never thought I would need to go 'barefoot' to find it but I should have thought about it as much as I like to walk around without shoes.

I finally put these shoes on last night and they feel wonderful and they fit like an extension of my feet.

Well made and cute to boot; can't wait to take them off road.


Exactly what I needed and wanted for trail running and hiking. I was looking to replace worn out running shoes that never performed too well in mud, over rocks, all the fun stuff! These are sturdy, comfortable, and lightweight They also fit like a gem, with the cable laces easily adjusting to the width of your foot.
