Hmmm Meindle… I had a pair that fell apart. The mid sole collapsed and the outer sole completely delaminated. They were returned to Germany but were rejected as faulty. I’ve had many, many other boots (Zamberlan, Koflach, Salewa, Scarpa, Asolo, La Sportiva, Salomon, Brasher etc) and these were the only ones that have fallen apart. IME, they are fantastically waterproof and comfy from the off – right up until they fall apart. So beware, they are brilliant, they just may not last as long as you think a £200 boot should.
As for Gore Tex vs non Gore Tex. I’ve never had a boot without a liner that didn’t leak – eventually (i.e. after full day’s bog trotting not over time). When multi day backpacking, I use Gore lined leather, for 3 season day walks, trainers (of various flavour) and just get wet (of add Gore Tex socks).
