(Dictionary entry) Sneakers: feminine plural noun
... In her shoes
Distinguishing marks: woman! How to recognize it? Of course from sneakers. It's too easy to flush out femininity in the hallmark of a lipstick, a perfume or an ornament. You recognize a woman (mostly) from shoes. And if she is wearing a pair of trendy and colorful sneakers as those on Playgroundshop.com, certainly she will move (or has already moved) a long way.
And remember: "no sneakers, no party" (cit.)
