SmartWool loaded its PhD Outdoor Medium Women's Crew Sock with a host of technical features to give you blister-proof performance on the trail. However, we suspect that you'll be pulling this plush, ultra-comfortable sock out of the drawer long after you've put the hiking boots away for the year.

  • Soft merino feels great against the skin, insulates superbly, wicks moisture, and naturally inhibits odor
  • Nylon adds durability, while 2% spandex content enhances the fit
  • Four-degree fit system features stretchy support around the ankle, upper instep, lower instep, and arch, so it fits perfectly and won't move around in your boot
  • ReliaWool high-density cushioning in impact areas provides all-day comfort and durability
  • Flat-knit seamless toe resists blowouts

These socks are so warm and comfortable! Am wearing them even when it's not that cold! Great buy.

Great socks

  • Familiarity: I've used it several times
  • Fit: True to size

Bought these for my wife- she loves them. Light enough for everyday wear (she wears them under casual boots) but also hardy enough for day hikes. Wash well and hold their shape.

Best Socks...

  • Gender: Female
  • Familiarity: I've put it through the wringer

By far! They are super toasty, super comfy, and still keep your feet warm if they get wet. I would definitely recommend these , I'm convinced everyone needs a pair (or three)!

You can't go wrong in purchasing any Smart Wool product. I'm hooked on them. Purchased several pairs for the winter and summer.

Best way to be blister free!

Seriously love merino, and there's no itch here, no blistering, and comfort for multiple days without washing. Phd knit is seriously supportive too!
