I walked from Roncesvalles in 2009 with the low, non-goretex version, and can't recommend them enough. (Unfortunately they got stolen at the big municipal albergue in Burgos, but I was able to pick up an exact replacement at the Decathlon sports chain.) I also picked up the low, goretex version when I was back home and alternated between the two for town and country walking for a couple of years after.
The lacing system is just incredibly good and surprisingly robust, but all four shoes did eventually fail (the plastic clip went brittle and cracked in each case). However, this was all after pretty heavy ab/use, and the shoes were close to worn out anyway, so rather than picking up spare laces on ebay, I happily tossed them and have bought a fresh low, non-goretex pair to walk from Seville this year.
I bought the low pair because this isn't bouldering, this is walking over nicely graded paths and tracks, and you (or at least I) don't need any extra ankle support. The extra weight and cost of the mid are real disadvantages, along with the reduced ventilation.
I bought the non-goretex pair because the ventilation is really good (the goretex ones are noticeably warmer), and cool feet are happy feet. I also have some sealskinz waterproof socks for when it rains hard, and this combo worked well last time for the typical alternating weeks of scorching sun and driving rain.
If you're buying blind over the internet, note that I have had to buy the size up for all my Salomon shoes, although they do fit extremely well after. (I have weird feet, though -- my second toe is ~5mm longer than my "big" toe.)
