TRAIL TERRAIN
TR01 / ANATOMY

Protection where the mountain demands it.

Integrated grip

Anti-slip yarn woven directly into the sock helps keep the foot stable inside the shoe, especially on descents.

360° ankle protection

Perimeter reinforcement protects exposed areas from rocks, roots and lateral impacts.

Seamless toe

A clean seamless construction designed to reduce friction points during long efforts.

Adaptive compression

Progressive support that stabilises the foot without restricting natural movement.

Technical fabric

High-resistance technical polyamide with antibacterial properties for demanding conditions.

TR01 / PERFORMANCE PROFILE

Temperature

Designed for trail running throughout the year.

Cold All year Heat

Medium compression

A secure fit without an excessive feeling of pressure.

Low Medium High

Less friction. Lower risk of blisters.

Integrated grip, adaptive compression and the seamless toe help reduce unwanted movement, friction and moisture build-up during long efforts.

FRICTION CONTROL
TR01 / CONTROL SYSTEM

Control does not mean stiffness.
It means precision.

01 / LOCK

Foot stability

Integrated grip helps reduce unwanted movement between the foot and the shoe.

02 / SHIELD

Impact protection

Perimeter ankle reinforcement adds protection on exposed mountain terrain.

03 / FLOW

Natural movement

Adaptive compression follows the foot rather than locking it into a rigid position.

DESIGNED FOR THE DESCENT

More grip.
More protection.
More confidence.

A note about colour

Colour may vary slightly depending on your screen, brightness settings and device.

Between two sizes?

Choose the smaller size for a closer, more stable performance fit.

TR01 / FAQ

Everything you need to know before heading to the mountain.

Fit, grip, compression, temperature and care. The key answers about TR01 in one place.

01 What type of trail running is TR01 designed for?

TR01 is designed for training, races and long efforts in the mountains. Its construction prioritises stability, protection and control on technical terrain, especially during descents.

02 Can the anti-slip sole come off with use?

No separate rubber layer is glued onto the sock. The anti-slip yarn is woven directly into the structure of the fabric, helping maintain grip without relying on an applied external piece.

03 Does it help reduce friction and blisters?

Integrated grip, adaptive compression and the seamless toe help reduce unwanted foot movement, friction points and moisture build-up. This may help reduce the risk of chafing and blisters during long efforts.

04 What level of compression does it have?

TR01 uses medium compression. It provides a secure, stable fit without creating an excessively restrictive feeling.

05 Can I use it all year round?

Yes. TR01 is designed to balance protection, breathability and comfort across different conditions throughout the year.

06 Can I also use it for road running?

Yes, although TR01 is specifically designed for trail running. Its ankle reinforcement, grip system and protective construction are primarily intended for mountain terrain.

07 Which size should I choose if I am between two sizes?

We recommend choosing the smaller size. A closer fit helps keep the sock stable and allows the support system to work as intended.

08 How should I wash TR01?

Wash at a maximum of 30°C, inside out, and avoid tumble drying and ironing. This helps preserve the fabric, reinforcement zones and compression.
