Kayanos are great shoes. I think they are easily the best runners I have owned. At the moment I have some Nike Pegasus which I bought because I got them half price. They are pretty good also imo.
Of course, Cliffy will tell you that all of these "commercial" shoes are shit and that you should buy some obscure brand of runners that are only available in one store in South America and you need to place an order by registered post, but Cliffy is a little odd when it comes to these things.
I also have a pair of Vibrams and I can see the sense behind them, but they take some getting used to and if you don't make the adjustment properly, you can really f**k up your feet.
