I have the Gore-Tex version, and have been using them most of this year. When I saw them for a good price last week, I bought a duplicate pair(first time I've ever done that-always trying something new).
My favorite shoe ever.
Had them in snow a few times, in shallow water dozens of times, and they've proven waterproof. When they've gotten in water high enough to get inside the shoe, they dried overnight.
My feet have stayed comfortable in them from 10-100 degrees with the same ankle-high Asics running socks. I wear Integral Designs eVent Shortie gaiters with them to keep mud and rain(and very rarely, snow) from getting in.
Traction is good, too. I've climbed lots of steep, rocky trails in them, and have a habit of following streams by hopping from rock to rock, along with walking on submerged rocks, and haven't wiped out, yet, except for on some slick clay banks that no shoe would have held on to.
Another thing that isn't a feature, but has worked out really well, is that they are practically self-cleaning, body and sole
They get muddy almost every week hiking, daily when I'm walking hills regularly around home, but have only been scrubbed down once, and that was months ago. I wore them to church while out of town visiting last weekend.
For anyone they fit well, they're worth a look, IMO. I certainly have no complaints.
Oh, there's one in my avatar, too
Have another pair of Merrells that are very light, and offer little support, but are comfortable for just wearing around.
