Not too enthusiastic yet. I always buy size 10 and it always works, but in this case it feels like they're a bit large. With 5 finger shoes, your toes have to be in the pockets all the way, so large in this case means that the extra space is behind your heels, which makes it uncomfortable. Then again, the toe pockets feel pretty tight, so I'm not sure if I would fit into the next smaller version.

The Vibram Fivefingers concept is interesting: Vibram has been around for decades and so far they only made soles for other shoe manufacturers. This is their first own complete product on the market. The shoe is not much more that a protective layer of rubber (with a thin anti-sweat layer inside), so you do indeed get the barfoot feeling, without the risk of hurting your feet on sharp objects. Perfect first product for a company that used to make soles only - brilliant idea.

It looks pretty silly though, so if you don't like people staring at your feet, this is not for you.

Another drwaback is that you typically don't use socks with them, so it better be warm outside, as the shoes themselves are so thin that they hardly isolate.

I'll probably use them every now and then for a walk in summer, just because it feels good to walk (almost) barefoot, but otherwise they'll mostly stay in the closet.
