Favorite socks

At first I was reluctant to wear wool socks of any kind on summer hikes and to the gym where it gets really hot. But these are so much better than anything I have worn, including synthetics. I used to wear cotton socks to the gym as a rule, but now I wouldn't think of it. No more sweaty socks, no more athlete's foot. YAY!

Some pills and signs of wear over time, but very minimal.

Versatile Outdoor sock

These socks aren't advertised as hiking socks, but I wore them on 6+ mile hike and they were awesome. The lightweight feel was nice and I didn't have any blisters. If you want durable socks that are not to bulky like traditional hiking socks these are for you. Very pleased that I can wear these on short or long hikes. Very much a versatile outdoor sock. Does everything they say they will.

I puchased these for my mom, since she had never experienced socks that didn't consist of cotton. They blew her away. She was thrilled with the warmth and comfort of these socks. Once you buy a nice pair, you realize that the extra $$ is worth the investment! She asked me to please just replace all the socks in her drawer, she will never be wearing cotton in the future!

These are reat fitting socks with cushion at toes/balls/heels and thin extra support at the arch. They are not too tight at the ankles but they do not fall down. I love these socks and have purchased more in other colors. They did shrink a bit after the first washer/dryer cycle but they fit my size 7 feet perfectly. They were scratchy until I washed them with fabric softener.

Great socks, great service!

Excellent fit. I enjoy the areas of different knits all over the foot -- cushioning in toe & heel, more support in the arch & top of foot. They don't spin on my feet like some non-wool socks do. Nice and warm on these winter nights, and still wick away any moisture. Be sure to turn them inside-out before laundering in warm water, and drying on medium.

Really like these socks

I am able to wear these socks in my road and trail shoes and still have room to move my toes. I have run in the mud and rain at temperatures as low as 33 degrees and my feet stayed warm even when wet. The only reason I gave the socks 4 stars is that I don't know how they will perform in colder temperatures.

If you are on fence about these socks, buy them. You won't regret it. They will perform surely, feet are warmer in damp, rain in my Gore Tex shoes. Now, just plan to wear them with shoes that are already a half size larger than you normally wear as I've done. They are thicker than average socks. I love them.

I've had one pair of these for 3 years now, and I have spent 100+ days on the trail wearing these exclusively. Not a single hole. With the exception of a little crunch from not washing them enough, these socks are still going strong.

Stacy W at on 09/22/2013
I love Smart Wool socks. These were a pretty good price. Love the color. The were a little more padded than I had thought they would be. Considering they are outdoor light they are pretty thick but Smart wool makes great socks!

Favorite Hiking Socks

I love these socks. I resisted wearing them when my husband bought me my first pair because my feet tend to get hot and I hate scratchy wool. These keep my feet cool and and have never ever felt scratchy.
