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 ÖtillÖ, 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.

Saved me a couple of times

This is probably the best shoes for climbing, hiking, and jogging in wet conditions. I took it to couple of waterfalls, immersed in water, climbed rocks, and it helped me gripping to the ground like magic. It actually saved me from slipping and falling a couple of times.

Innovative product

These are good, innovative shoes. I bought them in the saddle in a size too big and they're very spacious length wise. I actually wonder whether in an ideal world I'd have needed to size down from my usual size. They're not as comfy as my Stealths but do a great job of keeping the water out. They feel a bit thicker on the sole, presumably due to the lugs, and only two niggly points: 1. I have narrow feet but the mid section is particularly narrow, even for me. 2. Maybe it's just mine but they're verging on being an odd shape... Like they kind of bend Inwards slightly rather than being straight. I wear them to the gym nonetheless and they're comfy and practical.
