Have had these in a few colours and sizes now with no complaints from me or my kids. They're not itchy and they're warm.
Hi David,
That is wonderful news, thank you so much for sharing your experience with us. We hope you have a great day. We are excited to welcome you back in-store soon! 💙

Bought these in a couple of sizes and colours. They're very warm and not itchy. They also seem to be lasting well, they're just tossed in the washer and dryer and haven't shrunk or pulled badly.
Hi David,
We are so glad to hear you're enjoying the socks. Thank you for your review of them. Have a great day! :)
Jessie
Warm and fit just right
It's good. I am very satisfied with this. These socks are very thick and warm.
Hello Jieun,
Thank you for your feedback.
See you soon !

great socks, really warm, super comfy and excellent quality, especially for the price.
Still blissful (that's why I bought so many).
I don't hike. In fact at 80 years old I don't get out much at all! But this is the first time my feet have have been comfortably WARM in the house (which does have well-used CH). Bliss!
Good fit comfortable and warm
Really warm, very comfy, better than expected!
Great Warm socks
Good quality socks however I would prefer them warmer for British weather. I would probably buy them again only if they were on sale.
Good/soft /compatible product for winters
Not recommendable at all

How to choose the right footwear for hiking
To be well equipped in winter, we recommend you follow these guidelines : Warmth: Warmth provided by a warm pair of socks (ideally containing a suitable percentage of wool) Breathability: Choose the sock according to the intensity of the hike and make sure you wear a breathable model to minimize moisture. Boot height: Adapt the height of the sock to the height of the upper and preferably choose high models if you want more protection.
Pack of 2 pairs
This model is sold in packs of 2 pairs of socks in the same color.
How to select the right size for your hiking socks
Benefiting from the properties of the spandex used in all our socks, they conform to your feet and stay firmly in place when worn. Given that the length, width, and volume of our feet is always different, we advise you to try on your socks in store before purchase and then test them in use before setting off on a long hike.
