I have the Boulder version and they are fantastic boots, and have been very comfortable from the first time I slipped my feet into them. I do a lot of walking on rough ground surfaces and the pair of boots that I am wearing right now, were put into use in mid September 2013. (This entire dry season plus.) I will put the replacement set into use as soon as the first rains fall, in the next week or so. I always purchase two pair, as I generally do not have access to good shopping here. I am looking forward to equally good service with the new pair.
