I am male. I have size 11 feet. I buy cotton socks in the 9-12 size range, with coloured toes and heels so they can be paired.
So what in the name of God Almighty posseses two women, both size 6 1/2, to steal the fucking things and wear them mismatched because "pairs are boring and yours are comfier than ladies socks".?
Buy your own FFS.
