>>623176>These are my current choices:I don't have any experience with the Vasque brand but I see they have an UltraDry lining, which is a Goretex type breathable-waterproof material and that's good.
Now I do know Merrell makes good boots, I have a pair of their Thermo6 (in black) that are my winter work shoes (machinist here) they're 8 years old and still going strong.
But as both the Vasque and Merrells you listed are insulated, I'm wondering if they might be too warm for the indoor work you're doing?
My Merrell Thermo6 aren't really insulated but they are rubberized and waterproof (though non-breathable) and can get a bit too warm in the later winter/early spring, depending on the weather but they are good for sloshing thru slushy parking lots and doing a bit of snow shoveling after work.
My rest-of-the-year work shoes are black New Balance running shoes, which are cushy and comfortable for standing in front of a mill all day erry day, while cheap enough ($50) that it isn't an issue replacing them every coupe of years.
