I love most of burton's gear and I had some pretty high expectations for these boots (the price was a bit much, but I gave 'em a go). They are fantastic. I do a lot of boarding in the Teton Range in Wyoming and it gets super cold. These guys held up great and the warmers really helped on the sub, sub zero days. If you don't get cold the warmers might be a bit much, and I would recommend the Ions.
