I'd go with 11M - L, 11W - L, 8W -M
I bought the XL. I wear a size 11 women's shoe. I bought the XL because I wash in the machine and use cold water, and most of the time anything wool will shrink. I also do not dry in the dryer--hang in the laundry room. I've washed one pair once and they seem to be great. They do not fit tight, but that is the feel I wanted--hope this helps. Gail
The ones I got were for a man's size 12 - x-large. The female size was 13 or something like that.
Hope this helps
