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

    As you can see it very clearly says "ultralight" under the description. Don't be fooled like I was folks. At least when I received my order it was actually the "light" model and not the model I ordered in the description. Yes, there is a difference, but the main difference for me is I ordered the "ultralight" for a reason and that reason didn't include receiving the "light model instead. I've ordered from Sierra for years now and this is the 1st time I've been bamboozled. I know Sierra has always been good about returns for me in the past but I've never not received the product I thought I had ordered and paid for.

    These socks are lightweight (great for summer). The texture feels like they are 15-20 compression socks. Great for me as I get older, but it may not be what you want. I wish I had bought more with my free freight order.

    Light but nice cushion. Great for warm weather walking and hiking.

    Another great pair of SmartWools! I got these to wear with my new Scarpa hiking boots. They provide great cushion, and warmth. A little heavier than some of my other SmartWools, but just what I was looking for. I like the stripes on the top edge as well. :)

  • “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.
