I bought these boots and we've had the warmest winter that I can remember. I never fired up my snow blower this winter. So, my review is based on the observed quality of these boots. They are easy to put on over shoes (I bought them one size larger than my shoe size to ensure easy use). They are very heavy rubber and it looks as if they'll be long lasting. These might be a bit too heavy if you walk a mail route but for the average snow shoveler or snow blower user I'm sure they'll work just fine. I really like the obvious quality of these boots. But I'd be happy not to use them next year, though. See? Global warming is never bad for everyone.
