Long enough to cover my knees, and being 6'2", with long shins, I found that bizarre. Still, a comfortable sock. No holes to plug, yet!

I love these socks. They are thick enough to keep my feet warm on cold days and thin enough to fit in my boots perfectly.

Great sock for the price! I prefer wool socks to synthetics as they keep their shape much better after repeated used and don't get "brittle" and fall apart when dried in the hot dryer or by the campfire or when you have to use your camp stove to dry everything after skiing into that creek that i told you about last week which was covered with ice but today turned out not to be, dumbass.

I am a huge advocate of Merino wool and these socks definitely fall into that category. They have all the really good properties of the best Merino wool and Backcountry.com has given them a great cut so they fit amazing and they last a very long time. I go between these and the Cocona socks from Backcountry.com depending on how thick of socks I want at the time. Really great socks for a lot more than just skiing!

Just came back from skiing, worn both socks, I am size 6,5 or 37 for Europe, bought the S/M size. The socks are too long, it is not comfortable at all to have them above the knee, easy to get blisters at the back of the knee on the other side they stay up so you can easy put them more of them just above were your boot ends. I am 158cm(5,2"?). They stay put all day and that is really nice. I have had some problem with pressure injuries, but these ones were really comfy, with no prints or anything to make the surface uneven. They are not superwarm and were to cold for me skiing, then I am also one of them that freezes alot. They stay pretty dry, don't smell even after several days wear. Overall good sock for good price, but could be shorter and a little warmer.

Midweight Merino Ski Sock - Very warm and comfortable. They come up over my knee and I've got long legs. No problem with the construction or durability myself.

Good socks, plan and simple.

Great until the first wash. I ordered two pairs... and now have no pairs. The first use after the first wash i blew through both of the toes on both pairs... one on the left and one on the right. (So i guess i really have one pair left) the didn't hold up at all...fell apart like it was their job. My feet are pissed.

These socks are a great thickness. They keep my feet nice and warm, while not adding too much to stuff into my boot. Super soft and, of course, they never smell.

Love these socks, only I'm 6'2" and the S/M goes all the way up to my knee, and just a little bit above that. They're very comfortable, but the stitching on the toes is letting go, and I'm getting holes in the toe as well. I've only had these for about 2 and a half months.

These socks are awesome! They are really comfortable to wear, provide a little extra padding in my boots, and keep my feet toasty snowboarding. I wear a size 12 shoe and I'm about 6'1", the L/XL can stretch up onto my knee, definitely covers the entire calf.

These socks are warm, functional, and the best part is that they are not so expensive as other brand name socks

Merino equals never-stink-o. I've worn these each several times and been amazed that they don't ever get funky. I wash em anyway, just in case. Yeah, they do come up a little over my knee. But at least they stay there instead of sagging down and bunching up. Oh yeah, my feet are warm when skiing and they're great for wearing with shorts while out ballin' in the streets!

These sox fit great, stretch up pretty high on the leg, above your knee if you want them to, really lightweight and thin, backcountry makes amazing stuff for sure! comparable to smartwool no doubt!

love these socks in my AT boots. My AT boots have a little more room than my alpine boots, and I like a little more cushion and comfort. i have worn mine 10 times already and still going strong.

These socks are nice, the material and the fit of the foot were great. I wear an 8.5 mens shoe and the s/m fit my foot well. Where they lacked was the fact that they went above my knee when I put them on. Over the calf indeed. Good thing there is a great return policy, as I am not one to roll my socks down, or have them above my knee while skiing.
