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.

Love this Shoe

I am still new to exercising with a barefoot shoe. The Primus Trail Iffley Road gives me a little more sole for rugged terrain. Before switching to these barefoot shoes I always got blisters on the back of my heel or inside of my toes (from my toes being squished together.) So far, I have had no issues with discomfort and that makes being active so much more pleasant! It also doesn't hurt that the style of this shoe looks amazing as well. Five stars all around.

So far so good ...

So far so good.
Thus far I have worn these shoes without the insoles that are provided, however I will be putting them in (my feet are very narrow, so I think this will help close the forefoot space a little).

I initially ordered a size 7.5, as my previous shoes, Skora, were that size. However, Vivos run larger, so I had to return and got a size 7 - which are great.

These have great grip, and really provide the underfoot feel specific to barefoot/minimal running shoes.

Super easy (gratis) returns, really appreciate the return label in the box.

As a point of reference for people transitioning to barefoot/minimal shoes, I used to wear a size 8.5 in Asics back in the day.

Looking forward to buying more pairs. Thanks Vivo!
