I use mostly Columbia gear for some pretty serious outdoor adventures, and generally consider their waterproof tech, especially outdry rain shells to be the best you can get at any price. However, I don't (and wouldn't) use any of their footwear.

For waterproof footwear, breathable membranes don't work well in my experience, they quickly tear and leak. The membranes are just too delicate for the forces and flexing on a boot. A really well built traditional leather boot with external waterproofing like Sno Seal applied daily is both more breathable, and more waterproof. Failing that, heavy rubber boots like commercial fisherman wear are really the only totally waterproof footwear.
