I kinda like the spider heels and the Giger heels. They're fun, if not overly tasteful. I'm much less bothered by the clearly fun shoes in this thread than the ones that somebody though were legitimately good looking.
Saw this in the Kintetsu department store the other day. Forgot the manufacturer's name. EDIT: They are by Magnanni. The pair on the bottom, just out of frame, are some very nice Grensons that I haven't found a counterpart to online (i.e., at a sane price).
