Primus Trail Swimrun Womens


Wear your sustainability statement with the Primus Swimrun FG, designed for endurance over land and sea. Using recycled plastic bottles to create a quick-draining mesh that minimises water-weight. The lightweight construction is paired with low-profile lugs for off-road traction and a neoprene ankle collar to keep out grit, ready for amphibious adventures.

We're confident that after experiencing the joys of natural foot freedom, your feet won't want to go back to 'normal' shoes.

So confident, we've introduced a 100 day trial to all orders. If you change your mind within that period, we're happy for you to return your shoes for a full refund with no hassle.

Your trial will commence automatically from the date your order arrives. Simply check out with your shoes as usual and we'll take care of the rest. (Standard Ts and Cs apply).



The Swimrun collection was developed in collaboration with OÃàtillOÃà, founders of the Swimrun World Championship. Seamlessly transition between wet and dry while keeping out grit and silt -- perfect for triathalons or any extra-sloppy trail runs.

Totally worth the money

After having knee surgury and going back to work, I needed a shoe that was comfortable for both my everyday walking, and being on my feet all day!
I have nervous about spending €150 on shoes after not being at work for a month but when I tried them on when they arrived- I was sold.
They are worth every cent!
If you are on the fence, just do it. You wont regret it!

Fab but narrow

This would be a very good trail shoe for running. You would just need to wear a thin sock, because it is not roomy in that shoe. It seems to be neater around the instep, and the normal width at the toe.

Otherwise, be sure to wear a sock that goes up your heel a bit, because the neoprene section will rub you if you only wear secret socks. They are pretty hot.
