If I could afford it I would get rid of every cotton sock I owned and buy only SmartWool socks! They rule in every category, including the elusive style (ok, maybe you don't look that hip with sandals and fluffy earthy green wool socks! But you bought them because these socks DO WORK!) Don't deny the gravitational pull you have to hit the 'Ad to Cart' button. They call to you, young grasshopper, and you must answer!

I've used Thorlos and other brand socks and after just one season of use had the elastic wear out in them. The only way you would have to buy another pair of SmartWools is to lose them! That has been my only problem, my dryer seems to eat them and I somehow have random singles left! This is a serious sock that other sock's wish they could be like when they grow up! Like others have said; Look past the price this is an investment that won't disapoint you!

I forget how many pairs of Smartwools I have now of varying thicknesses because they are so comfortable. Even after years of use the inside of the sock resists piling and stays soft and smooth, unlike every cotton sock I've ever worn. And it's true what they say about wet wool still being warm. After a day of hiking in knee to waist high snow (which was beginning to melt in March) in Colorado I took my Smartwools off at the end of the day and was amazed that my feet had been warm given how wet the socks (and boots) were. Fantastic socks. Cotton = bad. Smartwool = good.

I've had a pair of these trekkers for years & the only thing I've noticed is part of the Smart Wool name on the soles are warn away. Very comfortable & temperature adjustable, meaning they'll keep your your tired dogs warm when necessary & not overheat them on the other hand. They dry quickly & being wool, insulate when wet. Good long term investment.

Of all the hiking socks I've tried, these are the best. They are comfortable, they don't stretch out or sag, and soles are nicely cushioned. I bought one pair just to try them out, but ended up buying a couple more for an upcoming backpacking trip. They are definitely worth a try if you're looking for a nice wool hiking sock.

These are really comfortable and seem to hold up well. I wasn't sure how I would like the wool socks but they are great.

I just backpacked (with 40 lbs.) to Keet Seel (Anasazi Indian Ruins) at the Navajo National Monument near Kayenta, Arizona. Anyone who has hiked to Keet Seel know the 17 mile round trip trek through Keet Seel Canyon is 50% in water up to your ankles. Having said all of this the SmartWool Heavy Trekking Crew Socks preformed magnificently. No blisters, feet never felt waterlogged, and after washing twice looked brand new. SmartWool in my backpack from now on!!

These socks are the best. I've been using them for several years in orienteering races and adventure races. They provide outstanding cushion and I have never had more than a pea sized blister using them, even after 14-15hrs of continuous trekking on trails and off camber bushwhacking. They dry quickly enough (the key is also wearing shoes that dry quickly - no waterproof shoes!). I wear a size 15 shoe so these socks go a long way in helping make the very limited selection of trail shoes more comfortable to use.

I always had a problem skating with cotton socks where my skates would rub in certain spots, and my toes would freeze. Then I bought these socks, and it did the trick. Keeps my feet warm, while providing great cushioning against my skates. I also used them on some cold weather hikes, or simply wearing them in the house when the floors are cold. My boots are insulated, so they are a little too warm for the general hike.

Im a guy with a allergy to wool, it always made me at least itch, and some times get rash even with a t shirt and or another layer between.
But, over last few years Iv read about how great this merino and smart wool items are, so I decided to try it. ITs Great! I gave mine the test, I just did not hike in them on a balmy 99 F day here in Oklahoma, I mowed my yard and have worn them while working in a blazing hot kitchen etc. My feet did not itch and in fact my feet were more comfortable than when Im wearing my fav pair of cotton outdoor socks.

Im looking forward to fall/winter to try out other clothing made from this material.

I bought these socks as a stocking stuffer for my sister who now loves them. This is a lot coming from someone who refuses to wear wool on account of it being too itchy - which is certainly not these case with these. Since I can convert her, these socks deserve a 6-star rating.

My feet didn't get any blisters, and after 5 days of wearing these socks they didn't even smell that bad. Sweet!
