I wear Chippewa logger boots. I find them plenty comfortable for working in, but would shy away from wearing them in a marathon or tri-athelon. I'm extra happy with them since late winter when I was cutting up a tree that came down in a big wind storm. I was cutting a small limb, about three inches in diameter...... had my foot on it, but apparently not well enough. The chain grabbed, limb rolled up and over my boot taking the saw with it. It happend in the fraction of a second, no time to react. I'm happy to report all my toes are still 100% intact, thanks to my steel toed Chippewa boots !
