In my experience Smartwool socks are worth it. These are warm and cozy and just feel great on my feet, even for a full day of hiking or mountaineering. when combined with sock liners they're fantastic.

I found them true to size, though for socks that's usually pretty easy. I wear a 12(US) and the XL is great.

They have been very durable for a three and a half years of use with almost no wear to date. I have three pair and rotate them, so they do get a pretty light duty cycle. One pair did pill when I forgot to turn it inside out before putting it in the dryer, but it's still very usable and that was my fault. Normal wool sock care still applies: turn them inside out and use gentle wash cycle and avoid the dryer when possible. I line dry these whenever I can.

Smart Wool socks are the absolute best socks in the world. They are extremely comfortable, odor diminishing, stay dry and are great with hiking boots. I wore these in Tibet in the winter and between my boots and socks, my feet were always the most comfortable part of my body. I did layer these particular socks under other Smart wool socks while in Tibet, which is probably why my feet felt like they were walking on a cloud. No joke...

I have these and the heavyweights and also the
extra heavyweights, being a person who gets cold toes and fingers
I like these up to around 45 40
You can add a liner if you wanted . They are very comfortable this is a great weight
for just everyday winter weather! Trust me once you go SmartWool of any weight you will never go back!!!

These socks are the best. They fit well and are so comfy. Just came back from hiking the Grand Canyon in these socks and not a single blister in 17 miles!

Great to take along on a long hiking trip. They are a great fit and keep your feet warm on the colder weather trips. Can't really go wrong with these

I wore these socks while traveling in New Zealand. In the warm climates and the cold climates the were great. Merino wool is the best material around.

These socks are the best on the market

For 20 years I have worn these socks hiking, mountain biking, backpacking, to work (home-care nurse), gardening, shopping, to gym work outs, even sleeping......everything but surfing or showering! And during these 20 years I have gone through a surprisingly few pair. No holes even, just more cardboardy feel when they are done for. A stand alone product, worthy of this gal's applause!

Best effing socks in the world. Bar none.

Smartwool socks are at the top shelf of hiking socks. These medium cushion socks feel great and wick away sweat with ease. BUY!

these socks are great around town and in the woods. Even when my feet got wet from walking in the rain and through creeks the socks held up and my feet stay comfortable all things considered

Great socks, used them on multiple military marches w/ over 80 lbs of gear-- best moisture management I've found out of all the other brands I've tried. I swear by them as do several other Marines in my platoon. Only downside is they tend to fray a little but so far, overall effectiveness has not changed.

It was a search to find the right brand and size for my husband. He wears a size 13 shoe -- regular size socks don't fit. It was worth the effort to find this online store though. Especially since all of his Smart Wool socks are now worn out with holes from continuous wear, which were purchased in another state a few years ago. Although they are pricey in comparison to other brand hiking socks in retail stores, he swears by these in particular for their comfort, coolness, and wear. Thanks for making such a quality product! By the way, my husband’s birthday is in January I'll be putting in another order of socks.

Thus far have worn these on a couple of short day hikes with hiking boots. They are great! Very comfortable and breath well. I have many different brands of socks and by far perfer Smartwool's light and medium weight socks. They fit true, I wear a 13 and the XL fit perfect. While these have not pilled yet all of my other Smartwool socks have but not much.

They are too bunchy and loose than I would like. I got a small and they are still too big.

I bought two pairs of these: one for my husband and one for my dad who were about to go on a 4-day hike in Alaska.
They loved them.
They were comfortable enough to wear with BRAND NEW BOOTS and dried quickly.
These socks are AWESOME!!!

My sock collection is made up mostly of smart wool socks for the winter and cycling socks for the summer. Smartwools have worked great from kicking around town, to camping in the Wasatch. No down side, I love 'em.

Love these socks. Wore them all day fishing and my feet loved them. I also wore them to work one day, my feet stayed very comfortable even working in an office. I thought that they might be extra warm being a mid weight sock.
