Remove insole and dry at room tempreture. Keep out of direct sunlight and avoid putting on a radiator.

LIQUIPROOF PREMIUM PROTECTOR. With wear, your shoes may loose some water resistent quality that is applied to the textile of the shoes. This product can be used to replenish the water repellent qualities.
Repair Options
Laces and insoles can be replaced.
End of life
Once you can’t repair or don't need them anymore, send us your old Vivos and we’ll make they sure they’re given a second life, or if they’re really well-loved, we'll store them until we launch our recycling solution.
Feel the earth
Tough, all-terrain trail trainers – one step closer to circularity
Fit
Better Balance and Posture
Foot-shaped fit enables toes to splay supporting balance and a stable base of support.
Feel
Improved Coordination And Agility
Thin sole allows the thousands of nerve endings in each foot enabling the sensory feedback the brain needs to move with skill.
Flex
Improved Strength and Natural Movement
Flexible footwear let the muscles and tendons load and recoil, supporting stronger, more resilient feet over time.
Run and roam wild
Built for trail running and adventuring closer to nature
We're on a mission to create a fully circular shoe – a new Vivo made from an old one, which can in turn be made into another. The Primus 3.5 is a big step forward on this journey.
With an already mechanically recyclable outsole, the challenge is making an upper from 100% polyester, which can be recycled. The new Primus Trail 3.5 upper takes us from 34% to 76% polyester, of which 93% is recycled. Why not 100%? Because some parts of the upper still need extra durability that polyester can't yet provide. We’re working with our partners to figure out this final piece of the puzzle.
multi-terrain
Giving you grip and ground feel on everything from wet and dry, rocky and firm terrain.
Urban
Stripped-back soles for barefoot living — so you're never too far from nature, even in the city.
Fit, Feel, Flex
For natural stability, natural sensory feedback and natural strength.
Firm Ground outsole
The Firm Ground outsole is made sticky rubber compound that provides excellent grip and durability. With a 3mm base and 2.5mm lug height, plus a textured arch for zonal grip (ideal for technical trail movement), this sole will keep your feet firmly planted on multiple terrains - wet to dry, concrete to rocky.
Sole base
3mm
Tread Depth
2.5mm
Welcome back the wild.
Human beings aren’t separate to nature, we are nature. When we listen to its rhythm and connect to its intelligence, we thrive. It's time to get outside and rewild.
