Which size should I choose?

These socks are unisex. Choose your usual shoe size: each size covers three shoe sizes (36/38, 39/41, 42/44 and 45/47).

How high is the upper?

These are mid-height socks: they cover the ankle.

Do they help prevent blisters?

They reduce friction: silicone strips hold the foot in place inside the shoe, while a targeted compression zone supports the ankle. A well-fitting shoe is just as important.

Can you feel the terrain through them?

Yes. At 35g per pair in size 39/41, their thin construction keeps you in close contact with the shoe for precise footing on technical terrain.

Are they made from merino wool?

No, these are synthetic socks: 56% polyamide, 32% recycled polyamide and 12% elastane, with no wool. They contain at least 32% recycled material.

The fabric is described as durable, but these are thin socks (35g per pair in size 39/41): like any lightweight socks, they wear with the miles.

How should I wash and dry these socks?

Wash them at 30 °C maximum without fabric softener, and leave them to air-dry. Do not tumble-dry. They are made from polyamide and elastane, synthetic materials that release plastic microfibres into the environment during washing.

What are the delivery times for this product?

All orders placed by midnight are prepared the next day. In France, orders placed before 1 pm (excluding weekends) with Chronopost 24h are dispatched the same day. Delivery then depends on the carrier and takes 1 to 4 days in France. Delivery times for Europe and the rest of the world vary by destination.

Can I return the item if the size doesn't fit?

Yes, absolutely. You have 30 days to return it and get a refund or an exchange. Return shipping is free. The item must be new, unworn, unwashed, and have its original tag.

In summary This content is written by AI

Customers particularly appreciate their comfort and secure fit: most find them comfortable, well adjusted and pleasant to wear both for running and in everyday life. Thin, understated and efficient, they provide light support that is appreciated on summer trail outings, while several customers praise their perceived quality. They also hold up well in caving: after two months in this demanding activity, one customer says they have not changed. A reliable choice for running in spring or summer.

Excellent socks. I wear them often for caving. It's quite demanding on socks, and after 2 months, they haven't budged.
