What would I like to do with them, you ask? I'll tell you...
I'd like to slowly stroke my fingers down the length of her nylon soles. I'd use a light feathery touch to start, then switch to light spider tickling. I'd like to poke my finger in between her stockinged toes, one at a time. I'd go further, but after all, she is your girlfriend. You lucky dog!
Thanks for the pics. Please share some more pics of her nylon-clad soles.
