The only mountain shoe with invisible fabric.
Primus Trail Knit FG.
You've already experienced freedom and movement on your feet with the Primus Trail FG I and II.
Now you can take it to the next level.
This knitted mesh fits your feet like a second skin. It contracts and stretches with every flex, rotation or stretch of your feet.
More movement = more breathability.
As you move, the yarns stretch, allowing air to flow in and out with ease, keeping your feet fresh in any situation.

It's not just the fabric.
The Primus Trail Knit FG also has all the ingredients your feet love:
- Total freedom. The wide last allows your toes to spread and move just the way they want to: without restriction. Reducing uncomfortable chafing and maintaining the natural linearity of your toes.
- Maximum feel. The multi-directional lugging of the Firm Ground outsole matches every terrain shape. Letting your foot act and have the freedom to do what it needs to do: feel, move and make it stronger.
- Protection yes, but just the little you need. The Vivobarefoot sole protects your feet from the elements. So you can go into nature in the most natural and lightest way. The only thing that will weigh you down will be the regret of not having them on your last adventure.
- Zero Strain, Zero Drop. With no heel, your body weight is evenly distributed over the entire foot. Reducing pressure on the toe area and relieving your back of tension. So you have more control and more balance in every step.
