I love these, I feel that this is what all shoes should be like. My only issue (its kind of a big one) is that they don't make this shoe in a size quite small enough for me. The smallest they have does fine, but I really want to go down a size because these move a -little- too much. But they are fantastic and comfortable (they are the only shoes I fall asleep in). Generally I wear them with performance toe socks for comfort.

As a dermatophile I would warn about wearing these on long athletic treks without getting really used to them. They do rub between the toes and most people don't have much in the way of protective skin built up there. I am not a runner, but if I was I would work my way up into these shoes but have something more familiar standing by.

On the whole though these shoes make me feel like I live in the future. I wish this company made gloves too.
