Primus Trail SG Womens DNA

Produced using animal free products and processes.

Breathable Mesh
Breathable Mesh

Synthetic multi-ply materials, to deliver optimum lightweight breathability and comfort.

Eco Rubber
Eco Rubber

A no-sew material, made from recycled tyres, with high abrasion resistance where you need it most.


Our new soft ground sole gives superior grip on wet terrains. It is quick draining, for minimal wet weight, with a lightweight ankle collar for support.

Built around the concept, less is more. Less shoe, less weight – more freedom to move. We had a vision for the lightest movement shoe possible; a shoe that followed the natural shape of the foot and had the least possible interference with human movement.


First pair and I'm certain they are not my last

These are my first pair of minimalist/barefoot shoes, but I’m certain they are not my last. I’ve had them for about a month, and overall I really like wearing them and I like how they look. They are comfortable even for my weirdly shaped feet (wide ball of the foot, narrower heel) for the most part. There is one spot where they are not comfortable yet, and that is because the back of the shoe comes up higher at the back of the ankle than would be just right for me, and I like to wear short socks. One other thing you might want to know about before buying these is that they don’t have a tongue. They are more like water shoes, so they are not the easiest shoes to put on. These things are slight annoyances to me, but they do not keep me from wanting to wear these shoes all the time.

Great shoes!

Fit is wonderful, shoes look great, very grippy on the trail. Very happy with these shoes.

Runs Big

Upon ordering, I was under the impression that these run true to size based on previous reviews I had read as well as recommendations from the website, so I ordered my normal shoe size. However, they were really big when I got them. I ended up returning them for this reason and will be reordering a smaller size once the refund hits. I really like the look of this shoe and I feel that with a proper fit, they will be a new favorite of mine.
