The Kamik Icebreaker isn't a run-of-the-mill rainboot, and with their work-wear good looks, optional lace closure system, removable felt insulating liner, great traction, and relatively high shaft height, these are a solid option. They even won our Editors' Choice award last year! However, we didn't find the Icebreakers to be as comfortable as slightly more traditional options, primarily due to Kamik's choice to forgo insoles for more general liners. Their additional inability to take a supplementary insole, plus the fact that we could feel the liner wearing our beneath our feet, made us further doubt whether they were as good as some of the other options in our test.
So while these are a good option, we think the Bogs Ultra Classic High is a better choice for general use, comfort, and ease of use. And if you're looking for something to help you stay warm in the worst weather, definitely take a look at the Original Muck Boots Company Arctic Sport.
