EMU Australia's Yancoal is a women's biker inspired mid-calf boot that looks great and protects at the same time. Tough yet chic, they are made with waterproof full grain leather and oiled nubuck, and lined with Australian merino wool. A full asymmetric zip allows the easy on and off, while the durable, waterproof rubber outsole delivers grip and traction in damp conditions. Amping up the fashionable look are metal studs in to the welt.
