I agree that conditions are an important determining factor. Since I hike in Ohio, Indiana, and Kentucky, and don't go out in heavy snow (say, more than 2 or 3 inches), low hikers are a four-season shoe for me; since I prefer Gore Tex, they're not just dry-weather, either.

Of course, I'm only a major tool, so you outrank me... smile

(Sorry, couldn't resist.)
