I just started wearing the last pair of Montrail Hardrocks that I bought up (with much online searching) after they were discontinued. So far, they are holding up fine, even though about 10-11 years old. Will they disintegrate due to age? Not so far, but we'll see!

At least they still fit and support better than any other shoe I've had. New Balance shoes with SL-2 lasts give a comparable fit, but they don't have lug soles so are less stable on uneven ground. I'm taking along a spare pair of shoes on my upcoming car-camping/dayhiking trip, though, just in case!
