I ordered three different pair of Smartwool socks in orange, as I wanted the most complimentary color for my orange jackets.
This one, 6544V, was not only the nicest orange color, they did fit very well and were the softest. Comfortable and thin for the early fall.

The other two pairs were 8758... Read More

    Love these socks for running. They tend to shrink up even with machine wash cool and line dry, so I sized up this time. I wear size 8/12-9 women's street shoe (9 wide or 9.5 Medium running shoes).

    A very lightweight, thin wool sock. Color and size appear true to photo and description. I thought I would like these socks, but after wearing them for a day, by late afternoon I had deep creases above my ankles because the top of the sock was so tight. I got these in the large size (my shoe size runs around 10) and my ankle size is average, not big. By end of day, it was quite uncomfortable. I love the color, so I am keeping them for now, but I know I will hesitate before putting them on again.

    They are Smartwool socks. Always tops in my book. What else can I say?

    • Answer Generally, a medium runs from a size 6 to size 8. This is a wonderful sock - comfortable, warm but not too hot.

    • Answer 7 to 9-1/2 according to the sizing provided by STP. Simply put the cursor over the "S" "M" or "L" and the size will pop up.
      Answered on 8/7/2014 7:57:04 PM by Sanpan from Palm Harbor FL
    • Answer This style and brand MEDIUM is for womens shoe size 7-9.5. If you click on the s/m/l.....the shoe size pops up right about it. That is the case for most items on this website - especially all socks.
      By the way - these socks are awesome!!!!
