They're an awesome pair of heeled Doc Martens: the girly "Darcie" style, and they come (or came - I'm not sure whether you can still get them) in a variety of different colour schemes. Mine are patent black, and I'm standing there showing off the chunky 3" block heels.
I have actually worn them outdoors under a pair of skinny jeans, but since I was doing the photoshoot in the house, I sported instead black hold-ups and tight hotpants! Lounging about showing off my long sexy booted legs felt great and I certainly enjoyed taking the photos:
