For some reason, human beings seem designed to really dig walking barefoot on grass. Seeing a corner of the market, Krispy Kreme (of all things) have now unveiled...the living grass flip-flop.

The world is momentarily speechless. Yes, it's surely just a bit of fun. But you wouldn't think it if you read the press release, which equates walking in these shoes to a healthful, one-with-Nature stroll in the park. It's a little too straight-faced to be comfortable with. (So let's not forget what flip-flops - and doughnuts - can do).

I'm going to track down a pair of these, simply because I'm curious how grass survives an hour of trampling, let alone the claimed use-life of 4 months. And, yes, they're fun. But if you truly want to bring the countryside into your city life, why not grow a vertical garden - or join the resistance?
