    Ensure solid comfort when you tackle the trail this chilly fall with the SmartWool PhD Outdoor Heavy Crew Socks. Designed to fit smoothly into your hiking shoes or boots, the PhD Outdoor features a 4 Degree Elite fit system for improved stretch and recovery to keep the socks in place versus sagging down into your footwear.

    • Merino wool's antimicrobial qualities inhibit feet funk while elastane fabric offers comfortable stretch
    • 4 Degree Elite fit system uses two elastics for greater stretch and recovery to keep the socks in place
    • ReliaWool technology in high-impact areas provides longer lasting protection
    • Strategically placed mesh ventilation zones supply ventilation for temperature and moisture management

    "No soggy feet"

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size
    • Size Bought: Large

    Gave these to my dad as a gift. He was a pretty big skeptic when it came to SmartWool socks. "they will be itchy... my feet always sweat...." Well boy has he changed his tune now! He loves them! and has bought countless pairs since. He loves that his feet stay dry the entire time he is wearing these socks. They don't irritate/make his feet itch at all like the typical wool socks tend to do. Definitely made a believer out of him.

    Athletic Fit

    These socks are high quality and quite warm. Comparing them to the smartwool trekking heavy crew sock, these are not as fluffy/lofty as the trekking version. The weave seems to be a bit lower profile and denser than the trekking version, and the fit is more tailored/ tighter, with the thicker areas selectively placed. They may be a little bit less warm than the trekking version, but the fit is much less bulky. Personal preference will tell which is better.

    Dry as can be :)

    The most amazing thing about these socks is that I stayed completely dry during a hike in the snow. I even broke through iced and snowed over streams, and did not feel a thing. When I got back to the cabin, my boots were wet, and my socks slightly damp on the outside, but I couldn't feel any dampness on my skin. Props to both Merrell (my boots) and SmartWool (these glorious socks).

    These socks... omg, these socks... omg

    Have a size 11eeee foot and ordered these socks in L. Fit perfectly at the heel and they do not bind toes. I had them on for ten minutes or less when I knew that they were possibly the warmest socks I had ever worn. The padding in the heel makes standing or walking for long periods a breeze. I am looking forward to trying these socks out during the warmer months when my beekeeping duties require me to lug heavy weight from one place to another. My feet are always worn out by the end of the day come April-June, from all the working on my feet and carrying around full honey boxes. Once you know how good your feet feel inside these socks you will be satisfied even at 26 dollars a pair. I am not a Dr. but if your ankles have a tendency to swell or if you are diabetic I recommend trying one of the Over-the-calf versions.

    The Smartwool PhD socks are amazing!!!

    I'm an avid hiker and been hiking for 7 years now. The only socks I wear are the Smartwool PhD as they hug my feet so well, breath and feel so good. I was so excited to find this heavy weight option and wore them on my Rainier climb. They were the only sock I wore, no liners needed. LOVE THESE!!!!

    Unanswered Question

    Will these keep my feet drier than medium phd socks? I wear phd medium at work in currently 20 degree f weather where I am in and out of a truck. My feet stay mostly warm but by the end of the day my feet are wet and slightly cold from sweat. I am wearing Skechers composite toe (required by work) work shoes (like tennis shoes) which are mostly leather and may be preventing the socks from airing out. I am wondering it the thicker heavy phd socks will keep my feet drier since there is more fabric for the moisture to move into keeping it away from my feet? I suppose I should also keep the heater off of my feet in the truck to reduce sweating as well.
