How to measure

Stand on a sheet of paper with your heel against a wall and mark the tip of your longest toe. Measure from the wall to the mark in centimeters, and match it to the foot length column. Measure both feet in the evening, when they're at their largest, and use the longer one.

DESCRIPTION

The Primus Trail II Firm Ground is our original, best-selling trail-running sneaker. It’s light, durable and flexible for wide-ranging trail adventures that bring you closer to the earth.

Continuously improved through athlete testing and material innovation, the Primus Trail II FG has nothing more or less than exactly what you need – made with high-performance, recycled, vegan* materials.

First and foremost a trail runner, the Primus Trail II FG also excels at fastpacking and hiking. Its low profile even makes it popular for outdoor-forward city lifestyles, including HIIT workouts and strength training.

The wide, thin, flexible build offers supreme sensitivity and natural mobility on uneven ground. The quick-lace system allows for fast on-off and easy adjustments. And the Firm Ground sole balances sensitivity, grip and speed on varied hardpack terrain, building natural strength with every step.

MULTI-TERRAIN

Giving you grip and ground feel on everything from wet and dry, rocky and firm terrain.

Multi Terrain
URBAN

Stripped-back soles for barefoot living — so you're never too far from nature, even in the city.

Fit Feel Flex
FIT, FEEL, FLEX

For natural stability, natural sensory feedback and natural strength.

VEGAN*

*The main materials in all our Vegan* products are synthetic and aren’t derived from animals. We don’t (yet) have the transparency we need over the production of all the small components (such as adhesives and dyes) used in these products to ensure they meet vegan best practices. So, whilst we believe the shoes are vegan, we’re not yet able to guarantee it and want to be fully transparent.

BREATHABLE MESH

Breathable, lightweight and comfortable.

PUNCTURE RESISTANT

The Pro5 Puncture Resistant finish is a lightweight and flexible 0.8mm layer on the sole. Protective underfoot to keep painful bits out, but still letting all the feeling in.
