According to the manufacture, the correct sizing, based on shoe size, is: XS (1-3.5), S (4-6.5), M (7-9.5) and L (10-12.5).

I find that the SmartWool women's socks run a little small, at least in my size. I wear shoe size 6 to 6.5 and have a narrow foot, so according to the chart I should wear size S. I've bought several socks in this size and they are all slightly small for me, especially after washing (I do not put my SmartWool socks in the dryer).||I have finally realized this and will purchase size M for myself from now on.||These are fabulous socks at a great price. The STP description doesn't say that they have a cushioned foot, which they do. This makes them incredibly comfortable to wear.
