Personally had two pairs of harkila boots, first pair leaked ans split across the toes after three days hill stalking. These were a half price on sale from John Norris so I sent them back and John Norris and they sent them back to harkila, to start with they said there was nothing they could do with them. After a polite email they agreed to replace them with another model that were coming up on sale shortly.
They arrived as stated and they leaked after 3months aswell so I gave up and marked it down to experience. But that's only my opinion cheers matt
