I used to wear those a long time ago, but the regular version, with the sewing in the front. I think I had 3 pairs of them, in different colors, wore it most of the summer.
They don't any arch support, so if you're actually gonna be pounding the pavement a lot, these aren't the best. But they looked cool, or so I thought/think. Also, I remember somebody I know saying that once they got wet, the rope sole started deteriorating like crazy.
