I took these shoes on a 2.5 month trip to the Andes. I climbed sand-dunes, 5000m mountain peaks, walked countless miles of trails and roads with the shoes. After I got home, I took the shoes off and put on another pair which started to give me some trouble... so I put them back on. They lasted another 6 months. All in all... the amount of wear and tear they took was amazing.
It was not waterproof though. Within the first 3 weeks, the GTX membrane leaked. What can you expect though... the membrane is so crappy anyways - less thick than a piece of paper... its going to break down if you are actually using the shoes a lot.
After about 9 months of solid use, with the grip almost all gone, there is still a good amount of flex resistance left in the sole.
I am traveling to central america this summer and I will buy another pair because they are breathable... dry out fairly quickly, and are light, grippy and agile.
