I still can't find any aesthetic appeal at all in those shoes, and I simply attribute it to a generation gap. But this story is well worth thinking about.
The ugliness actually appeals to some people, too.
Certain famous websites come to mind. On a tangential point, it seems like these things must be relatively cheap and easily accessible, and cannot become status symbols. Sushi is an example where aesthetic appeal is as important as its palatability. (I'm typing a bit aimlessly)
So, what about those NIKE Naked shoes (or whatever?)? They are less of a fashion statement because they stand out less, I presume?
Other than that, yes they are extremely light and comfortable...
