I saw them when travelling.
Two backpacking girls waiting for the bus wore them. One had red ones, the other one a pair of cyans. I prefered the cyan one, probably because her lower legs were rather muscular and she wore a white knee-long skirt. I used all the time i got to stare at the lower parts of this girl and memorize her appearence. And thats what i retain of her by now.
I did a little research afterwards. Most Amsterdam wearers bought them for travelling, as they are said to be "cute and comfy".
Neither sight nor memory trigger any desire to be strung up by the girl wearing the cyan ones, or at least the urge to get the admission to lick her wonderfull keens.
But i promise to think of them during my next rendezvous with the noose...
