FAQs

Are these suitable for road running?

While they can be used on roads, they are primarily designed for trail use. The outsole offers good grip on natural surfaces. For extensive road running, consider models specifically designed for pavement.

What is the advantage of the knit upper?

The knit upper provides excellent breathability, keeping your feet cooler. It also offers a flexible, sock-like fit that adapts to your foot shape and helps to keep out small debris.

How do I know if I have the right size?

Ensure there is enough room for your toes to splay naturally without hitting the front of the shoe. The heel should feel secure, and the shoe should feel comfortable without being tight.

Can I wear socks with these trainers?

Many users prefer to wear them sockless to maximize the barefoot feel. However, thin, moisture-wicking socks can be worn if preferred for added warmth or hygiene.

How durable is the Primus Trail Knit FG?

These trainers are built for trail conditions. The materials are chosen for durability, but like all footwear, longevity depends on usage and care. Regular cleaning and avoiding excessive harsh conditions will prolong their life.

Are these waterproof?

No, the knit upper is designed for breathability and is not waterproof. They offer some water resistance but will not keep feet dry in prolonged wet conditions.

What does 'FG' stand for in the model name?

FG stands for Firm Ground, indicating that the outsole is optimized for traction on hard, dry, and slightly wet natural surfaces like packed earth, gravel, and short grass.

Troubleshooting

Feet feel sore after initial use.

This is common when transitioning to barefoot footwear. Reduce wear time and gradually increase it as your feet and muscles adapt. Ensure you are not overpronating or supinating excessively.

Trail debris enters the shoe.

The sock-like construction is designed to minimize this, but for very loose or dusty trails, consider pairing with gaiters or ensuring the shoe is snug.

Grip is insufficient on wet surfaces.

The FG (Firm Ground) outsole provides good traction on dry surfaces. For consistently wet or muddy conditions, a more aggressive tread pattern may be necessary. Ensure the sole is clean for optimal grip.

Knit upper feels loose after some wear.

The knit material is designed to be flexible. Ensure laces are appropriately tightened. If significant stretching occurs, consider professional assessment, though this is rare with proper care.

Setup, Compatibility & Care

Setup: These trainers are ready to wear out of the box. Ensure you have selected the correct size for optimal comfort and performance. Due to their minimalist nature, an acclimatization period is recommended for new users, gradually increasing wear time and distance.

Compatibility: Suitable for a wide range of adult foot shapes, particularly those who prefer a wider toe box and minimalist footwear. They are designed for use on natural surfaces like trails, grass, and light gravel.

Care: To clean, gently brush off loose dirt. For more thorough cleaning, use a soft brush with cold water and mild soap. Allow shoes to air dry naturally away from direct heat. Avoid machine washing or drying. Regular cleaning will help maintain the integrity and lifespan of the knit material and sole.
