Great shoes for trail running

Very light and comfortable. Well designed, sturdy and the sole offers a decent grip on the trails, even on wet trails and rocks.
Quick release lacing system is OK, and it holds the shoe with nice fit around your foot, but it could be improved to work smother. If you don't like it, there is extra shoelace in the box included.
I am very happy with this pair of primus, they're my second pair of Vivo and since I get used to them I don't wear any other shoes. Even when it's snowing or raining they are still on my feet wherever I go.

Good product with minor doubts

I like many things about my new shoes. It feels and actually is very lite on the foot. My only doubt is about the heel, after wearing the shoe for a little more than two weeks, it hurts a little bit. I will further test it and see if the (small) pain persists.

great outdoor shoe

This shoe feels amazing on your feet. The sole offers more grip but still feels very natural. You can still feel the different surfaces on the ground.

The new soles are great to keep your feet warm.
I'm gone love wearing these this winter :)
