I bought many pairs of this particular model over the years. One thing I can say for sure: they are not very durable. At least not for real hiking. On the last pair, the stitching started to come apart during my second day of hiking. At the end of only 10 days of hiking, I had to throw the shoes away. At $110 a pair, that's an expensive shoe. On the other hand the shoes are roomy and the sole is exceptional when climbing on rocks: it sticks to the surfaces beautifully ... as long as is not wet or there is sand. The shoelaces are a joke, coming loose all the time. But I have old shoelaces from my old Brooks running shoes which never come loose.
