Really who doesn't love Smart wool socks that uses them?

Since using this sock, I can only think of one time that I got a blister and that was my own fault for wearing gore-tex running shoes in 95 degree weather for 50 miles. They keep my feet dry, while trail running up here in the wet, muddy Northwest.

The downside is their life span being wool. I can usually only get 100-150 miles out of a pair before they start wearing thin. For their price they should last longer.

Nice snug fit, I bought the size small for men's 8.5 shoe size.

Beside wearing smartwool socks everyday, I wore these socks over the 270 miles of the Long Trail, VT, this summer. I wore only one pair the entire trip (I did bring a back up pair) to test the durability of the socks. They held up incredibly well, and only wore through on the back due to the shoes I was wearing (Montrail Continental Divide, always chew up my socks). After 25 or so days without cleaning though, they did smell a bit, but it would be ridiculous to not expect that. I can't imagine wearing any other socks.

These seem to be a cross between Smartwool regular hiking socks and the Adrenalins. The nice, snug fit of the adrenalins with the thicker padding at the toe and heel. Personally, they are too hot for where I live 11.5mos out of the year. I love the Adrenalin but could see going with the PHD for cooler hiking. I think you cant go wrong with these under that criteria.

These socks are great, I use them for everyday summer and warm weather outings. The height is perfect for me, the never sag. The mesh on the sole is "cool" too.

this sock, while extremely comfortable, is not exactly a thin warm weather sock. it is considerably thicker, and i often suffer from the problem of sweaty feet -- this sock is not helping. i am reserving it for colder days (although not snow, since it is an ankle sock.)

if you are looking for a cold weather short sock, it is probably ideal. also, sizing is about right. i am an 8.5, and i ordered medium. it just fits.

These wool socks feel great. Compared with other synthetic / wool blends, these are more comfortable. They're great on short and long runs, except when very warm out. I have them in every color!

I've used all types of socks, and these are by far the best. The short ones are more of my day by day use socks, and they are great. My full height ones lasted over 1,000 miles and are still working great. Most comfortable socks ever, and its great to pay $12 for a pair socks I will be able to replace whenever they start to wear out.

Keep in mind, smartwool has a lifetime guarantee, so if they ever do start to wear thin, they will replace them for free.

Great addition to my sock drawer. When I'm wearing shorts for hiking in the summer, these get pulled out and I love wearing them all day long. Comfortable and helped keep blisters at bay in my new boots.

They are a great sock but they have a short life as most wool socks do. But as long as you have a Superfeet insert or something then they can last a while... I wear them with my North Face Prophecy running shoes and they work great...

My wife and I both got these socks because we anticipated a great deal of walking and a little hiking on our trip, which included the highlands of Scotland. Perhaps it's standard with a specialty sock like this, but from the moment I put it on, I knew this was not like the regular socks I usually wear. The fit and feel of it was remarkable, eliciting an "ooooh" upon first wear.

I don't know how many miles we walked with our Smartwool and Keens - pavement, cobblestones, rocks, hills and sand, but I loved these socks. I was able to hand wash them and they'd dry overnight for us. I had three pair, but could probably have managed with two if necessary.
