SmartWool Trekking Heavy Crew Reviews:


These are great socks for winter hiking. They fit true to size if you wear a liner underneath. They are fairly heavy, I would suggest the lightweight or PhD versions for summer hiking. These wick really well, and are plenty warm for winter hiking or even a day in the deerstand. I have put many miles on these, and they have held up well. You can machine wash these on cold cycle, but I recommend air drying, as I have had a few pairs shrink in the dryer. They will not shrink if air dried. If you have big boots, hike in cold weather, or want some super-warm socks, these are for you! Do make sure you have room in your boots for socks this thick, as they are really thick and pretty cushy!

Quite possibly the best socks in the world. I've been buying these for years for both my husband and myself. They are so comfortable I can't stand to wear any other socks on my feet. So glad they have them at Zappos now. They are thick and cushion, very soft (not itchy at all if you're sensitive to wool fibers) and very warm. OK, they're a bit pricey but you'll grab for them any time you need socks. I purchased some 100% alpaca socks thinking they would be softer and warmer than these, but they weren't even close. Get some and I bet you'll be back for more pairs.

I've been backpacking for over ten years, and SmartWool have always been my #1 choice for socks. I've used these trekking socks for month long trips on the Olympic peninsula, the Wasatch range, Southern Utah as well as on various cold-weather sailing trips. They are very comfortable and are great for regulating the temperature of your feet given their merino wool makeup. They dry super quickly as well, which is great for some mid-trip washing. They also won't hold all that lovely foot odor. Fit true to size.

I am something of a sock connoisseur, so it means something when I say that these are the best socks I have ever owned. They are beautifully warm and comfortable to wear on a mountain or around the home (I'm wearing some right now). I only ever wash them on impulse, as they never smell or feel like they actually need washing unless you've been walking around somewhere greasy or muddy. They are rather thick though, so not much good if your boots are already too small.

I bought these for a friend for the holidays and she is really happy with them. She commutes on foot in the middle of winter months and so I wanted to get something that would keep her feet warm.
Worn around the house they are so thick they almost have a slipper-like feel to them and will always keep your feet dry/warm.
I love SmartWool and these are one of their greatest products if you tend to run on the colder side.

WOW, I mean it. I am very picky about socks, since I don't like to wear them. These are my first pair of wool socks and thick socks. My feet felt very comfortable in lace up boots and regular boots. My feet never got cold in 15-30F while working outdoors working construction wearing regular leather boots. My feet did sweat a little, but no odor. The price is worth the wear.

Saved My Feet

Great Sock! Have used these a lot this summer in High Elevations. They are durable and did a great job keeping my feet dry. I would have to admit I wore these consecutively for 4 days at one point and they didn't get smelly. I would suggest buying a liner sock to wear between your skin and these socks though.

These socks are a must have!

When many are complaining of cold and sore feet I'm always thankful for my SmartWool Trekking Socks. These heavy weight feet savers not only make my La Sportiva boots more comfortable but also add warmth and life to my feet. I've been using these socks for over four years now (not the same pair all the time) and they never seem to wear out.

Cushion and Comfort Sock

I use this sock in the Fall/winter as an everyday sock because it really keeps my feet warm. I also use it backpacking and trail running in the colder months because I like the cushioning it gives me. I usually will wear these socks multiple days as they stay clean and don't smell like a cotton sock will.It fits true to size.

Hiking through deep snow is the best test of a pair of winter socks, and these pass all around. Durable, comfy and warm in the coldest of settings. Make sure you have room in your boots for them because they are a bit thick. If you're tired of having cold feet you won't be disappointed.
