Love these!

I love these shoes! They are very comfortable, and hold up great during my runs, walking through mud, and puddles.I have received several compliments so far, and have bought my sister a different pair of Vivos because I am convinced that these shoes are cool, functional, and resourceful. It took me a while to find an ethical vegan barefoot shoe, so this one meets my criteria. My only suggestion would be to make the ankle opening wider for those who have wider ankles or feet because I can see how it would be difficult for some people to put these shoes on. I also think that these shoes are true to size once you put in the extra soles that come with them in the box. Overall, great product and will be making purchases from this company in the future!

Glad for the eco-friendly material use!

Wish there was a 9.5 in this shoe as it is a tiny bit snug for my taste, although others may be OK with their toes at the very end of the shoe.

Have needed to wear socks with these as the ankle area rubbed the back of my ankle raw when I attempted to initially wear them without socks, but they are perfectly comfortable with socks also.

Good ankle support, although wishing it was a little bit more rigid at times. So glad that they are recycling bottles to make these and makes me feel a little better about having to buy new shoes!

Love these!

I absolutely love these! I like the high top version of this to protect my ankles when I go hiking. They fit well, however, they are a bit narrow. Since wearing minimalist shoes, perhaps my feet have gotten wider. If I wanted to add a thermal insole plus thicker socks for a long hike, it'll be a bit snug. But this is better than any other shoe out there.
