How do they reduce friction and discomfort over long distances?

Comfort comes down to construction details designed for long days out. The terry loop cushions the arch against repeated friction, the shaft supports the ankle and protects the ankle bone from contact with the shoe, and the re-knitted toe seams eliminate any bulky overlaps.

Can they dig in or leave marks on the skin?

The cuffs are designed to be non-compressive, with no pressure points that dig into the skin or restrict circulation, even after several hours.

Will my feet stay dry and odour-free after a long day?

Yes. Merino wool naturally regulates temperature and manages moisture without any wet feeling, kilometre after kilometre. It also neutralises odours throughout the day, with no chemical treatment.

What are the delivery times for this product?

Hiking

Merino wool in its purest form

Typically, merino wool undergoes chlorine treatment for easy machine washing. This process leaves chemical residues in the fibres, in direct contact with your skin throughout your hike.

These socks take the opposite approach. Their chlorine-free merino wool preserves the natural structure of the fibre: softer, more breathable, residue-free.

63% wool for intense warmth. Polyamide for long-lasting durability. Seamless linked toes and non-binding cuffs for pressure-free comfort.

Because true comfort should never rely on chemical treatments.

In summary This content is written by AI

Customers mainly appreciate their warmth, comfort and quality construction. Several find them very warm, pleasant and comfortable, even in bitterly cold conditions, while their thickness adds to the feeling of protection. They have been appreciated for hiking, including between 1,000 and 3,000 metres, and recommended for winter; one customer found them warm and dry in those conditions. One point to bear in mind: it is still too early to assess their durability, as several customers have only worn them for a few days or weeks.

My son likes these socks and they work well with his boots. He was worried wool would be too warm and sweaty but has since realised wool regulates temperature so much better than man made fibres

These socks are a bit on the thin side but fairly warm….in boots thicker socks preferable, but they are well made,nice flat toe-seam and cuff not too tight which most sock makers overlook it seems.

I wear size 41/42, the socks fit perfectly, feel great, keep my feet warm, and even after two days of hiking, they don't smell at all. Exactly what I was looking for, I highly recommend them. I'll definitely be ordering more.

Working on a glacier at 3200m and wearing SPORTIVA boots, both pairs of socks are comfortable and warm, but these are more effective than the others.

They fit correctly. I use them for hiking in both summer and winter, as they are comfortable and I don't need double-layer socks (for me).
