My husband bought this shoe in molten lava for an upcoming trip to Glacier. He also has a pair of heavy-duty, waterproof hiking boots by Merrell, but wanted a pair of lighter shoes for easier days. So far he has just worn them around town, doing athletic activities, and just as casual shoes and had really enjoyed them. They are comfortable and cool, which is encouraging since his waterproof boots (that he has also been wearing in order to break in) are very warm, of course. During an adventure at a local park, one of our dogs got them very muddy. I called Merrell and they said that, like the Barefoot series (which I wear), these could also be thrown in the washer, after removing the insole. So far, so good... hope they do as well for him in Montana!
