Wool blend ankle sock

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: Large

Runs small. Thin but cool in the summer and warm in the winter due to the wool. I bought the Large as I wear a 10 1/2 woman's but I needed a size Larger.
So I gave them away.

Nice leightweight socks

    Bought these for my wife. Now she wants 3 more. Washes well, and a small fits her size 5.5-6 shoe size

    Won't stay up!

    • Familiarity: I've used it several times
    • Size Bought: Medium

    Ugh, I love Smartwool socks, but these were a huge disappointment. They fall into my shoes within minutes, no matter which shoes I'm wearing. Maybe this pair sized small because the fit of my other SW socks is perfect. I like the thickness and color (pink!), but sadly, this pair is going to the thrift store. :(

    I love these socks

      These are the perfect socks. They are comfortable and durable and they stay on my heel!! I ordered one pair at first but I'm definitely going to get more.

      Great All Around Winter Sock

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

      I bought this sock to wear running, at workout class, and to work (I like things that work in any setting!) I really like this sock - it is soft, comfortable, easy to wear. It is a little bit warm under sneakers on a warmer day, I'd go with something lighter if you're not looking for a winter sock.

      Fuzzy fast

      • Fit: True to size

      When I first put these on, the fit felt incredible! However, within the first wear, fuzz had formed all over the toe and heel of the sock -- BEFORE I had even washed the rocks. Already looking scuzzy within the first wear -- no bueno!
