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).

Why wear high-cut socks for running?

The edges of a high-cut shoe repeatedly rub against the ankle, especially on descents. The high cuff and its anatomical fit protect this area.

Do they help prevent blisters?

They reduce friction thanks to an anatomical ankle cuff, a reinforced heel and a left- and right-foot-specific fit that limits bunching. A well-fitting shoe matters just as much.

Are they warm enough for winter?

Though thin, they keep feet at a comfortable temperature during exercise. During long stops or in extreme cold, they do not insulate like a thick sock.

Can I wear them for hiking?

Yes. Their high cuffs are also suitable for hiking on varied terrain, including with high-cut shoes.

Are they made from 100% merino wool?

No: they contain 17% merino wool, 44% polyamide, 21% recycled polyester, 14% polypropylene and 4% elastane.

How should I care for these socks?

Follow the care instructions on the socks’ label. They release plastic microfibres into the environment when washed.

The reinforced heel area resists abrasion on rocky descents, and the durability rating classifies the fabric as hard-wearing. They are thin, though, and will wear with the miles, like any thin socks.

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.

Who did we design them for?

For trail runners and hikers on varied terrain who want a high cuff to protect their ankles from the edges of their shoes.

How warm are they?

Thin despite their high cuff, they can be worn year-round. Merino wool regulates temperature; in extreme cold, a thicker sock is a better choice.

What height?

High-cut: the cuff extends above the ankle, making these suitable for trail or hiking shoes whose edges reach the ankle.

What material is it made from?

44% polyamide, 21% recycled polyester, 17% merino wool, 14% polypropylene and 4% elastane. Merino wool regulates temperature and helps limit odours.

A high cuff you’ll barely notice

On technical trail runs, your ankles take a beating. Higher shoe collars create repeated friction on ordinary socks. And pure synthetics only amplify the sauna effect on descents.

These socks tackle both issues: a high cuff with an anatomically shaped top hem reduces rubbing at the ankle, while merino wool regulates foot temperature and reduces the feeling of dampness.

The reinforced heel absorbs shocks on rocky descents, while the left- and right-foot fit prevents creases at the base of the toes. All without weighing your feet down.

Because a high-cut sock should protect your ankles, not rub them raw.

Customers love these socks for their comfort, softness and breathability: many wear them comfortably even during intensive use and appreciate that they stay odour-free.

I love these socks. They're wonderfully soft, don't wrinkle, and my feet sweat much less than with other brands. I've been wearing the shorter version for over a year now and have just ordered the longer one for cooler days. Highly recommended!
