I've had these about a month and they are one of the most comfortable boots I've ever worn. The waterproof feature is working well so far, although I haven't spent the whole day walking through snow or wet grass. It's very cold here and my feet stay good and warm, but I wonder how they will be in the heat of the summer. I may purchase low cut Moab Ventilators. I had to purchase a half a size larger than I normally wear so it's best to go to a retail store and try different sizes before you buy. This seems to occur a lot with Merrell boots. Bottom line: So far I'm very pleased with these boots, but will update this review when the waterproofing is tested more harshly.
