Ordered the Adult size 'Medium' mid-calf.  I have a women's size 9 foot, that is barely a medium width (on the narrow side of med width foot).  I either wear a 9 or 9.5 shoe.  (I'd consider the "medium" a perfect fit for women who wear a size 10-med shoe.)

Length to long or short for you?  This should help: The sock top stops 12" up from the floor when worn.

Note:  I do NOT like tight fitting socks on my feet - and these are perfect.
