What makes a boot a heritage classic? Well, there rubber and leather boot styles were introduced in 1919.. making this style more than 100 years old, and still going strong. The upper is a seam-sealed waterproof buffalo leather, the boot is a modern upgrade to the original rubber, a waterproof and recyclable lightweight synthetic RubberHe shell with a deep and wide self-clearing tread design that holds up to snow, mud, and messy conditions. Unlike the original boots, which came unlined and frankly0 were not warm0 this has a moisture wicking soft boa lining and removable dual density PU foam footbed, for a boot that’s rated down to a nice negative four degrees. Definitely a boot to get you through sitting on the bleachers cheering the kid’s hockey play, through an afternoon of snowball fights, and around town in the wet and sloppy cold of winter. A mid-cut height, not too low so it won’t fill up with snow, not too high to make kicking them off at the door a chore, it’s the classic winter boot updated with modern materials while maintaining its heritage style.
