SmartWool Hiking Liner Crew Sock

These were more an experiment than anything for me. I almost exclusively wear Smartwool's trekking socks while I'm backpacking. I gave these a shot with some other sock combinations to see if I liked them... and I do. It turns out that I actually prefer to not use liners, but of the four or five types of liners I tried... these were easily my favorite. They are still occasions where I still use them, and when those times come around I always find myself impressed with how comfortable and durable these are.

If you prefer liners with your boots and socks... give these a shot. You won't be disappointed.

I always get cold feet really no matter what I have on for socks
I use the smart wool extra heavy weights but I tend to sweat a little
and then I loose the heat, I added these liners they work good my feet dont sweat and it keeps the good heat inside.
They actually feel like dress socks

I wasn't sure about using liners but I am glad that I gave them a try. On really cold days they help and I have also used them on very warm days as my only sock. They are durable for such a lightweight material.

I've used Patagonia and REI liners up until now when I wanted to try these since all mine have holes by now. These are slightly heavier then the prior brands, and I welcomed it - still light, but less likely to rip after a season. Substantial. I highly recommend these liners, they performed on the trail --and they can also hold their own in the city if I'm in a rush and they're the only socks I can grab. I plan to get more.

I always get holes in the big toe area of these liners. The fabric there is too thin. I love how they feel but after going through 3 pairs and getting holes, I cant justify buying them anymore. Trying other liners next.

Well, when I go out for longer, agressive trips I really like the benefits that liners give. Helps protect your feet against blistering, and helps to keep tape snugged up on your ankles. I don't really need to wear em in cold weather, but I'm sure for some there is a benefit. All around, a nice sock to keep in your drawer. It'll get used.

I have always used these primarily under a heavyweight sock

but these actually work great for a summer sock.

They are very thin and breath great also dry very fast.

All their socks are great. I use these liners for bicycling and hiking. They are a little thicker than my polypro liners, but not so much that they make my shoes and boots too tight. They were especially a good value when Backcountry had them on sale.

I wear these liners as a source of extra warmth, to further reduce friction and help wicking. They dry very fast overnight, just wring them out, spin them a few times and hang. As others have stated, they even make a great "dress sock" worn alone with shoes. In high heat, i've worn them alone with low hikers for fast short hikes. Highly recommended.

I use these socks for both trekking/climbing and as dress socks. For trekking/climbing they were very comfortable under heavier socks and did an excellent job of wicking away moisture. I didn't get any blisters, even with heavy mountaineering boots and my feet were stink-free (which can be a problem with my feet). They double well as dress socks as they are very comfortable as a stand-alone.

I have SmartWool sock from medium to heavy and have been very happy with them. These are for the summer and once again, SmartWool does not disappoint. :) Get them!

LOVE THESE. I was totally skeptical of liner socks but these turned me into a true believer. I've never escaped a climb without multiple blisters on my feet - by the time I got off Rainier I had TEN whopping blisters! Oof, that was painful. Well, I wore these on my next climb and they totally saved my feet. Warm, dry, comfortable, NO blisters whatsoever. I was so impressed. I've used them several times since then and they always deliver. I'll never head off for the mountains without them!

I bought these socks because my other sock liners went missing in the dryer, and the model has been discontinued. The seams on these are flat but they're not the flattest I've experienced. This makes a difference after 20 miles on the trail with a 50-pound pack.

I always get holes in the big toe area of these liners. The fabric there is too thin. I love how they feel but after going through 3 pairs and getting holes, I cant justify buying them anymore. Trying other liners next.

I use these as my year round sock of choice. These socks are soft, wick moisture away keeping my feet dry and they wear like iron. Front country or back country, these are super!

I use these with my black loafers and dress pants in the fall and winter time. I also use them with my dress boots. They are great because they keep your feet warm when it's cool, they keep your feet cool when it's warm, they make your feet smell fresh instead of stinky, and the black dye in the fabric doesn't fade overtime. I also use them for their intended purpose (as hiking liner socks, and of course they're fine for that too,) but I really love them with my casual dress work clothes. I wear b/w a 6 and a 6.5 in women's shoes, and the size small socks fit me just fine.

these are great to have on extended trips. If you wear these inside of your regular smartwools, you won't get as much sweat and grime on the full sized pair making them last longer without washing. With the liners, you can wash them in a stream and they will dry much faster than the regular socks.

Not only that, but the black ones make great dress socks as well.

They are okay, but nothing special, except the wool. If your regular line is synthetic then these are way better, but I have other merino liners that works better for me!

I'm gonna stick with the phd series from smartwool - found no one who beat any of those.

worked exacly as they were supposed to, dry feet mean happy feet.

Worked ok on 2-wk excursion into AK wilderness. Also bought the Fox silk liners and MUCH preferred them. My husband actually stopped on the trail, pulled these off (they were rubbing a warm spot) and put on his dirty Fox liners.

Wear them under the Smartwool midweight hikers, and you will increase wicking, and reduce friction between your foot and your boot, especially in the heel area. Therefore, less blisters and more enjoyment. Also, you can wear them everyday in the summer by themselves. I have even worn them as dress socks.

The fabric combination feels great and stays put. They're my coziest and least expensive socks.

These socks are really good. They feel great, stays in place and doesn't smell after a whole day walking in running shoes. A big recommandation from here!

I always take two pairs of liners on back packing trips. Wash one and wear the other. First day was all day off trail and i did not get any blisters. the second day i washed the smart wool liners and threw them on my pack to dry and put on some other liners (not smartwool) 3 miles later i had two hot spots on my feet. So i stopped waited till the smartwool socks had dried and hiked for the rest of the day with them on and no hot spots!

I'm ordering my next pair today.

Real light, truly breathable sock that provides some warmth but lots of comfort. Great balance of comfort, coolness and ventilation in this sock.

What can you really say about a sock? It's comfortable under my hiking socks, much moreso that a thin poylester liner (never tried silk). It wicks well. Being merino, it doesn't get smelly, which along with the solid black color make it a great travel sock.

These socks work out great for me. In the extreme heat and adverse conditions they really help prevent blisters. I am glad that I got them and will get more soon.

These socks are fantastic. I used them as a liner in 20 degree weather with nothing but a thin pair of cotton socks over them. They keept my feet dry and warm without adding a lot of bulck inside my boot. Love em.

Fell through the ice the first day of a three day trip and though my feet were wet, was never cold.

i wore one pair on a 7 day 75 mile backpacking trip in Sierra/King's Canyon (rinsed the trail dust out at the end of the day) and then climbed Rainier 2 days later with the same pair. they are the best liner sock i've ever worn. this sock is so comfortable i bought 4 more pair to wear at work.

Well, what and how much can you say about socks ? For me these are if not the best some of the best pairs of socks I've ever used.

Great when backpacking, I wore them for 5 days straight (washed in rivers) on a recent backpacking trip. They stayed clean and odor free, and dried fast when I washed them. The cushioning is nice too. Recommended!

They did exactly what they were supposed to. Kept my feet dry, warm and stink free. I wore them under thicker hiking socks for 4 days on the Inca Trail

I bought these socks to pair with the light weight Smart Wool Phd hiking socks for a 20 mile backpacking trip in Escalante. The socks were great no blisters and wicked moisture as you would expect from a Smart Wool product. Highly recommended.

Inside my snug, waterproof hiking shoes, these socks are just about perfect. They're lightweight, soft, never overly warm, they stay in place without being too snug, they don't bunch up or bind anywhere and they keep my feet perfectly dry. The only other thing I could wish for is that they self-laundered!

Warm when wet, warm when dry, last forever, fit perfect.

as usual, good product from smartwool. no scratchyness, good fit, nice and thin. hope they wear nicely.

This sock is very comfortable and fits snug around your foot. The sock helps wick away moisture and helps keep the stink down. I’ve worn these socks both as a liner and alone – they work great either way.

I wear these as a light hiking sock and a liner for my ski boots. I purchased one pair a year ago and went back for one more. Also, these seem to be a little more durable than other wool blend socks I've had in the past. The heels and the front of the soles have remained intact. PS. Don't tell anyone but I wore these to my cousins wedding beneath a very expensive rental tux. I danced the night away and they were much more comfortable than a typical dress sock.

These socks rode down my shins when I wore them with boots. They are more scratchy than I was expecting/hoping but not too bad. I would not want to use these as a liner b/c they are scratchy.

Light and warm!
