There is a review of these chain mail minimalist shoes in the last issue (no.9) of Barefoot running magazine. Pages 112 to 115.
They got really good ratings.
So they don't chafe (even without the provided socks) and they weigh less than I thought they would: 240 grams the shoe.
And the prize is reasonable if you consider that they'll last a lifetime and more (unlike any other running shoe).
