Excellent Trail Running and Workout Shoe

I got these shoes for my fiancé so that he would have some barefoot workout shoes for running and exercising in the gym. According to him, they fit great, feel great, and it doesn't hurt that they look nice too. :) Would definitely recommend—thanks Vivo!

Rugged Yet Tidy

These are very rugged, and I love the pull-to-tighten laces! My one concern is that the shoes may be a bit too breathable when it rains or during cold winds. I guess I'll find out over time and report back. I used to have Evo IIs which had more protection against weather but still had a low profile, but no shoes like that appear to be on offer currently.

My third pair of vivos

This is my third pair of shoes from this company. My first two I bought about 4 and 6 years ago. I really liked the feel and comfort of them. They were very flexible and comfortable. Those two were more fabric feeling material.
I was excited to try these shoes as they look a lot different then my first ones.

These pair seem comfortable so far. My only issue is the material it is made of seems more plastic, not as flexible and conforming to my feet. They are a good pair of shoes and I have been wearing them for a couple weeks. So far so good. They may last longer since there does not seem to be any seams between fabric material to rip.
