These boots are very comfortable and warm and held up great, except for the zipper. It failed after 8 total months of wearing. Because it kept splitting, no matter what I tried, they became unwearable. If I'd known I would get so little time out of these, I would have invested in a better boot. I definitely won't buy a zippered boot from Keen again, and may rethink any further purchases at all.
