I've owned my Merrell Moab Ventilators for about 2 years.  They've been very good shoes.  I find them very comfortable - good support, light, with good breathability.  I originally bought them for walking around Disney World.  They supported my feet well and my feet didn't over heat (make sure to also wear good socks, like the Cool-lite from Wigwam).  The Moab's also handle the trails that I travel.  Getting them wet has not been an issue, as they dry quickly and water doesn't affect the materials.  The sole has worn very well and is still has a lot of tread on it.  I haven't had to change the laces either.  I wear them mostly around town with some light trail and hiking thrown in for fun.  I also really like the looks of the shoe.

After two years, it is time to replace them as the cushion and support are failing.  The rest of the shoe structure is still in fine shape.  I'll probably get a new insole and wear them as my grubby shoes.
