To be fair etceteraism, Vivienne Westwood's Pirate Boots are of the highest standard. And if you've only worn them 10-15 times and now the sole has detached I'm guessing either they're fake or you've damaged them that way yourself.
I've had mine for over a year now and worn them hundreds upon hundreds of times, and about 1 month ago I managed to detach the sole from the toe myself, but I was on a night out and got them caught on something so it was my own fault.
Plus I know people who've got the original Pirate Boots from the 80's and there's are still immaculate, they last as long as you treat them I find.
