why do sandals make your feet stinky?

[insertnamehere]

you would think that with the ability for sweat to immediatly evaporate and with constant air circulation, sandaled feet would smell better than feet that wear shoes. not so. im sure anyone thats frequently worn flip-flops/thongs, tevas, or things of that nature know what im talking about. it kind of smells a bit like vinegar or something. what the hell is that all about?
