Stuart Weitzman has come up with a shoe he calls “Nudist,” and it does seem to have a certain lack of adornment to it:
Definitely meets my spec for Insubstantial. In a rare concession to reality, this flavor is Goose Bump Nappa; there’s also a black version, similarly textured. The heel is 4½ inches. Price is $398.
I can’t imagine any nudists actually wearing this, except to the occasional formal. (If the next question is “How would you know?” I just point to the shoes.) Certainly the shoe has little potential as beachwear. I plan to spend the next several hours not thinking about how I’d react were someone to show up at my door wearing these and these only, though I’m pretty sure I have a better chance of being struck by a meteorite, and indoors at that.
