The Smartwool PhD Outdoor Mid Crew Socks aren’t about slapping a ‘My socks were on the honor role’ bumper-sticker on the back of your car. Not that you won’t want to brag about the Wool-to-Wool technology that cushions your heels and forefeet for shock-absorption on the trail, and the upper mesh zones that cool your dogs on the ascent. Since smart socks hardly want to smell like a football locker room, Smartwool made these with odor-blocking wool. The cuff height and midweight wool work well when you carry heavy loads for backpacking trips.

Cold Weather Sock

    I wear these socks mainly in the late fall/winter and they do the trick. They are warm and they wick well when my feet get too sweaty. I tend to switch between these and the PhD light crew depending on the weather and my activity level. Keeps the odor away too! (No sock will be odor free if you don't let them air out; pulling the liners from your boots/shoes helps!)

    First Hike/Climb in them

      So I just bought these and decided to test them out on Longs Peak, CO over the weekend. I personally like my sock thinner than most in winter conditions and these were the right weight. They fit great, I am a size 10 shoe and 10.5 Mountaineering boot. I bought size MD and LG, MD fitting better since I have small ankles. If you have a fuller foot/leg and are in-between sizes I would go for the larger one. They are not constricting around the ankle and lower calf (crew socks) and are the right length for my La Sportiva Nepal Evo's. After 6 miles up to Camp with a 35lb pack through dirt, snow and ice I had no hot spots, no rubbing and plenty of cushion. My feet stayed plenty warm (Temp ranged from 50f to 20f). The only reason I did not give it 5 stars was because they started to pill after the first day and will probably not last very long.

      Great all round sock

        The form fitting cut of this sock is great. No sliding around either. It should be noted that they are on the tighter side comparatively speaking (a small fit); hugging your feet and ankles almost like a compression sock, which over time is not that great. My legs are very slim. I got size L for a 10.5.

        The fabric surface does not retain very well, after two days the surface was fluffy. Image is taken after three days of light wear, no hiking or long walks!

        Great all round sock

        Not blister free

          If you suffer from chronic heal blisters, as I do, these are not the cure. However, I do agree these socks are one of the best. They wick moisture away from your feet with true speed and efficiency. I have never felt uncomfortable while hiking in the summer or using them with my Keen winter boots. They fit well and are truly comfortable as an everyday sock. Good job Smartwool.

          my go to backpacking socks

            love these guys. extra padding in the heels and balls of your feet. compression over the top is great! i feel like i have fewer weird sore spots the next day. wick well. have never stunk near as bad as any of the cotton or synthetic socks i have ever used. great great socks!!!! i have some light ones for warmer weather. i wear these in cooler weather under my boots.

            Best socks for me, so far....

              I have been wearing these socks on and off since just before New Years both with my work boots and my hiking boots. In both cases they are warm and comfortable. I have had no problem with them bunching up or cutting into my feet like some of the much cheaper socks are prone to do. These socks are expensive but worth it.

              Warm comfy and stinky

                Warm and comfortable, but I must have some smelly feet because the odor blocking didn't work.

                Multi-day no stink for me, and my feet can get pretty damn funky w/ nice anti-microbial treated synthetic socks. As mentioned you will need to let them air out for a while intermittently when the start getting sweaty.

                Personally I like to have a couple pairs to rotate out, and turn the other pair inside out and hang off of my pack to let them dry/breathe. After a couple/few hours they're pretty much as fresh as just out of the washer/dryer. This system has gotten me through 5 day trips w/ no blisters or discernible foot funk at the end w/ just 2 pairs of socks.

                THE best

                  There is a reason they're pricey, they really are the best socks I've ever owned. The fit is much better than any of the Bridgedale, IceBreaker, Patagonia...whatever socks you want you want to compare them to. I think they're the closest you can get to a "stink-free" pair of socks, which might be a moot point because my feet never seem to sweat with them on. If I'm wearing shoes, I'm wearing these.

                  Thank you Smartwool

                    These are great socks. Period. Okay, I was unsure about spending $20 on a single pair of socks, but it is possibly the best $20 I have ever spent. The tight knit on the top keeps the socks in place, and saves room for the padding where you need it in the bottom. Multi-day hike foot pain is now all but gone. Buy some and your feet will thank you.

                    Hey I am about embark on the kokoda track...

                    Hey I am about embark on the kokoda track 96km of up and down mountains in very high humidity. What would you recommend for a good comfortable sock

                    would these be to much cushion for everyday...

                    would these be to much cushion for everyday wear? rather than the light cushion version of the same sock?
