Reviews

Great for mud runs!

I bought these Primus Swim Run trainers primarily for mud/obstacle runs. It held up very well. One suggestion: wear it with socks to avoid irritated skin around your ankle.

Super comfy

I'm a newbie to running but I'm in the process of changing all of my footwear over to some sort of barefoot/minimalist platform so the Swim/Run seemed like a great option.

I had to go a size up from what I'm used to but I'm really glad I did, the toe box is the perfect width and length. The sole construction feels really good as well, super flexible yet robust. I tried recently going out with the insoles in, this was ok but I think I prefer them without.

A good product for the trails

My Favourite Vivos

I love these shoes. The only downside is that if you use them on pavement the sole wears down (ball of foot) fairly quickly. I live in these all the time and dread having to put them away for the coming winter but have bought a pair MAGNA TRAIL MENS and Tracker FG Mens for that season.
