Product Customer Reviews

Were great for skiing! Didn’t feel the cold at all and they’re very comfortable. Thin enough that you can still wear your ski boots or regular shoes comfortably but thick enough that they keep you warm.
Very warm socks, very stretchy and durable and very good deal with the price.
Very comfy and nice fit.
Comfy, warm, feet don't sweat, but a bit itchy
Decently warm enough socks for active wear in winter weather. I use them on my commute to work on my bike and once I work up a bit of heat, they're warm-ish. The wool seems to be concentrated around the top of the sock and the thick synthetic fabrics hug your foot. A little disappointed by this as longer rides allow a chill to get in. Buy an all-wool sock if you're looking for something warmer.
Great products
2 different sized socks.

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,

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 !

Comfortable warm merino wool socks. Anatomically designed so need to follow the L&R label stitched in. Review questions make you laugh when the ask about abrasion resistance when you’ve only had them a week.But so far thankfully no holes in them 😉
Very happy with these for the everyday use on the coldest winter days in Scotland.
Comfortable and warm socks
Feet the feet amazing, I keep buying these and will continue to do so. I've slim ankle but would appreciate a little more room/give on elastic top to compensate for after numerous general 30° washes. Not uncomfortable mind, as I keep purchasing, being particular. Bonus, keeps the dirt and grime out!

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.
