The color of the sock is really nice and vibrant. This sock is great, breathability and moisture wicking is great, its sturdy but not thick so it's great for warm weather or under another pair if layering is needed. I bought a size medium and my size is women's 7.5 M, runs small but fit properly so ... Read More

    What needs to be said about smartwool? It's the best, only time I ever see it priced where I can afford it is at the Sierra Trading Post!
  • Not crew socks
    Verified Buyer Reviewed by MAC from Wisconsin on Wednesday, April 18, 2018
    These may be good socks, I haven't yet had a chance to wear them. I tried them on and they seem pretty comfortable, but without any real cushion, but that's because as advertised, they're very light and I expect to wear them in warm weather. However, they're ankle socks, not crew socks.

    They are not kidding about them being ultralight. They’re closer to being liners than socks but like all Smartwool products, they are very well made.

  • “I searched for phd. Are these the phd design,. And why r they on clearance?

    Asked by Pat from OR - Oregon on 5/12/2016 6:38:09 AM
    • It usually says in the description if they are PHD, if you don't see it on there, then I am assuming it is not.
      They are on clearance because that is what Sierra Trading Post is. A clearance/sale online outlet.
      Like any other store, they need to put merchandise on clearance to make room for new stuff.

      Hope this helps.

      Have a wonderful day.
