Kawasaki Players are probably my favorite shoes.
They never caught on in the US but were really big in Europe a few years back.
Hands down, the most comfortable shoes I own. They weigh mere ounces and perfectly contour to the feet. In addition, they fit like a glove and are just as flexible. I am a dancer, so I got attached to them for these qualities. Since first moving around in them, I pretty much cant use anything else.
I have never seen them on sale in the US so go buy them at YOOX.com!
