Aldershot - Royal Canadian
The "Aldershot" boot by Royal Canadian is a warm, waterproof, and stylish boot, fantastic for Canadian winters. The boots are rated to a -30°C temperature (although take that with a grain of salt; that will depend on several factors, including your socks, your circulation, your activity level, etc.). Complete with a side zipper, you don't have to worry about those pesky laces each time!
Available at Glebe Trotters.
