The Smartwool PhD Outdoor Light Crew is a lightweight sock for hiking, biking, running and more. If you're outdoors and ready for adventure, the PhD Outdoor Light Crew will be happy to come along for the ride. The blend of merino wool, nylon, and elastane wicks sweat away from your feet and dries out quickly, keeping you comfy in your boots, hiker lows, or whatever footwear you've got on. The 4 Degree™ Elite fit system wraps your ankle, upper and lower instep, and arch with bands that allow for flex and recovery. I like to call it energy for your feet.

FEATURES of the Smartwool PhD Outdoor Light Crew

  • 4 Degree elite fit system uses two elastics for greater stretch and recovery to keep the sock in place
  • Patented ReliaWool technology in high impact areas provides longer lasting protection to keep feet comfortable
  • Strategically placed mesh ventilation zones provide ventilation for temperature and moisture management
  • Flat knit durable toe seam for high burst strength

Rated 5 out of 5 by from extremely comfortable I bought these and some different styles of the same brand. All have been so comfortable and my feet are so much drier at the end of the day! I could not be happier with these socks. Great for work or just wearing around the house. So good I just ordered 5 pair for my Wife!

Rated 5 out of 5 by from great backpacking sock I bought these a while ago for a light to mid-weight hiking sock in my Salomon GTX's. They're the perfect height, perfect weight, provide lubrication to prevent blisters, and are well made. Liked them so much that I bought a couple more pairs (on sale) to use for skiing, as the full-length PhD's are a tad bit too long. If you prefer a lighter sock and not full length, then these are great quality socks and the price is right.

Rated 5 out of 5 by from Best Sock In the Universe Smartwool technology combined with targeted cushioning and snug fitting bands that hold the sock in place without cutting off circulation. I wear a size 9 in mens and the medium sock fits me perfectly. When you're out for light load hiking, don't even bother wearing a different sock.

Rated 5 out of 5 by from Great Fit and comfort I fly fish a lot and spend hours on my feet. It's important to me to have socks that hold up to that kind of rigor. I really like how they perform. In fact, I buy Smartwool for the entire family..

Rated 5 out of 5 by from Comfortable Socks Great fitting socks that stay in place all day and keep your feet dry all day long. Great for hikes, as well as keeping your feet warm at home. Great snug fit inside of a good hiking shoe resulting no blistering or swampy feet.

Rated 5 out of 5 by from Smartwool socks are great! I have various thicknesses of these PhD crew socks (light, medium, heavy) for fire/EMS duty, and training my strength & conditioning clients. I also have the low cut PhD running socks for my aerobic training. So far they are the best I've found!
