Classic Mountaineer Sock delivers heavyweight warmth and all-day comfort
What Our Gearhead® Experts Are Saying:
"On multi-day trips in cold conditions, these are my go-to socks. The cushioning is thick and plush, so I can hike or climb for hours without any hot spots. They wick moisture impressively well, and even after long days in boots, my feet stay warm and comfortable instead of soggy and sore."
We trust the Smartwool Classic Mountaineer Maximum Cushion Crew Sock to keep our feet happy and warm from the first step to the summit. Designed for long days in the mountains, this heavyweight sock blends plush comfort with technical performance, making it ideal for alpine missions and winter treks.
The ultra-thick merino wool knit regulates temperature and fights odors naturally, while the strategic cushioning absorbs impact to prevent fatigue and blisters. Reinforced zones boost durability for season after season of use, and the smooth toe seam eliminates rubbing inside heavy boots. From frigid dawn starts to summit views, these socks bring warmth, protection, and comfort to every expedition.

Great socks
Really nice high quality socks. I have skinny feet, and the thickness of these help my heavy leather boots fit better. I’m sure they are warm in cold weather, but I wear them all day long in 100+ desert heat, and my feet stay dry and comfortable.

Trash quality
- Familiarity:
- I've used it once or twice and have initial impressions
I have worn these socks twice, both times around the houses. There are multiple loose threads. The threads around the toe and ankle are starting to pull apart, and there is already the beginning of a hole around the toe. The elastic that keeps the sock up already seems stretched out and loose. These are quite possibly the most poorly constructed socks I’ve ever bought. Smart Wool is no longer a quality brand. Extremely overpriced, even on sale. Very disappointed. Avoid.

Great socks that wick away sweat
- Familiarity:
- I've used it several times
They are a great fit. The cushion in them makes my hikes more enjoyable. I really like how they wick away the sweat and keep my feet dry.

I would buy again... I hope a better person packs them up
[This review was collected as part of a promotion.] The socks are great, and I would 1000% buy them again. The shipping wasn't the best, and they heat-sealed one of the socks together with the packaging.

mountaineer socks
[This review was collected as part of a promotion.] Being an avid hunter and Outdoor enthusiast,I've been using your socks as long as I can remember. Their thickness and ability to dry quickly in challenging environments, is a big plus ! and they last a long time ! Don't let the executives take this sock off your lineup !!

5/5! Best Pair Of Socks I've Ever Had
[This review was collected as part of a promotion.] These are the most comfortable, durable socks I've ever worn! I wear a size 12, 6e shoe with extremely wide feet. These are one of the few socks that can withstand long runs/hikes.

Fantastic socks
These socks are absolutely fantastic. They are 100% worth the money. I've owned multiple pairs over the last 12 years and smart wool continues to improve on them. They were great to start with and they're even better today. I primarily use them as lounge socks.

Fabulous highly padded hiking socks!
[This review was collected as part of a promotion.] 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!

I will restock my sock collection with all Smartwool
[This review was collected as part of a promotion.] 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!
