These are by far the warmest coziest socks I have ever worn ! In Gore Tex boots in the winter my feet pretty much are invincible! They some how make already comfortable shoes even more comfortable. Took them backpacking though the Scottish Highlands in late autumn they were perfect on those cold nights so much so that my partner ended borrowing a pair! Couldn’t recommend these enough, worth every penny

I LOVE these socks!!!!! I bought them for the high quality I was already familiar with Smart Wool and how well their socks work with my sweat feet! I needed something with more cushion this time because I'm hiking the West Highland Way in Scotland next week and my plantar fasciitis flared. They have been the perfect with for added passing during my training hikes. You Are always getting a quality product with Smart Wool!

These are a favourite of mine and several friends, but not for their intended use. We wear them daily at home to keep our feet toasty on cold floors. They're also great when camping.The fit is looser than my other Smartwool socks, even though I always size down. They're definitely not a technical sock. They should also be good in winter boots if your boot fit is roomy enough.If you're in the lower range of a size bracket I recommend buying one size down.

Replacements for 4-5 year old same product.Note that they are thick enough that sock material compression and buffering between low top trail running Saucony shoes end up allowing a lot of foot movement in the shoe and the opportunities to stop and retighten things while hiking.Arizona terrain, one hike around 5 miles 1000 foot elevation gain out and back and the other 8 plus and around 2000 gain, also out and back.Durability rating is based on my much older pairs that have many 6 to 15 mile hikes on them
I've been using wool socks for about 10 years now, but another brand. I decided to try Smartwool because they offer thicker, warmer socks than the brand I use. And boy, are they warmer! My feet stay warm all day long in these socks! Total relief! Thank you Smartwool!
I’m a woman with size 9 feet. I bought medium in these socks, which is what the size chart indicates. They are constantly sliding down in my boots. I wear them for farm work. I still wear them, but the slipping is a real annoyance. They’re not that warm either. I still get frozen toes in Oregon weather. Would probably try something else specifically designed for women’s feet next time.
I have LITERALLY lived in SmartWool Mountaineering socks since 1997. I buy 3 pr ever single year, and my wife EVERY YEAR without fail since 2000 had bought me 5 pr every Christmas. YES; over $160.00 a year every year on SmartWool Mountaineering crew socks. These socks have been reworked/engineered and are NOT the classic. THEY ARE NOT THE SAME. The knit is looser, they arent as thick on the sole, they removed the woven in size on the side of the foot, they are NOT as dense or heavy. They are not as warm. They took a product Ive loved and lived in for DECADES and made it worse. Its a sad sad sad day in my mountaineering sock world. (and yes I even wear them all summer, either in my ATAC boots, Vasques or with my TEVAs) These 'new' socks called "Mountaineer Classic" ... MoreI have LITERALLY lived in SmartWool Mountaineering socks since 1997.

I bought a pair online for my boyfriend for Christmas, and he loves them! He immediately put them on and now wears them frequently around the house since the winter temperatures are still with us. Also, the red pops of color are festive. We've loved Smartwool for years and these Mountaineer Maximum Cushion Crew Socks didn't disappoint! He hasn't worn them for a hiking trip yet, but I'm confident in their performance. (I don't wear anything but smartwool socks for hiking and I feel I may need a pair of the max cushion for myself!)
I've been wearing these Mountaineering socks for 20 yrs. The thickest plush I've seen. I wear these mens size Large super loose socks, tho I'm a women's 8.5 wide foot. The loose-ness is for early onset arthritic cranky feet and I wear them pretty much 8 months a year.Issues: for looseness, I must cut down a straight line down front of shin. Then fold them over. Overwise too tight on my calfs and it hurts my skin.Drying... I learned not to dry much in a dryer. Overdrying causes inner sock to get bumpy. Still usable, just not as soft or plushy. I dry in dryer about 5 min to take off pet hair, then hang dry socks.
I used these on a summit of Lobuche, Nepal. Starting in the dark/cold morning I had G2 Evo boots (double lined), these socks, another pair of Smartwool Performance, Injinji liners and chemical toe warmers. My feet were warm! Not using these socks or the warmers but with the other socks and a pair of Lowa Renegade GTX my feet were cold on Kilimanjaro, which I didn't want to repeat in the snow.I actually had to remove these on the descent because as the day warmed and I moved more quickly my feet got too hot. The thickness is great but comes at a cost in terms of durability. I'm not planning on these lasting years, but even if these lasted one climb I consider them money well spent. Anything to avoid cold feet!
