Functional, fashionable, and (most importantly) animal friendly, the Vivien is the perfect boot for fall. As the temperature steadily drops and the days grow shorter, our version of the knee-length boot will keep you cozy and comfortable. Lest you think this is a shoe reserved for the cooler months, think again. Take to the field with your steed and protect yourself from the elements all year long. Mud splatters? No problem. Because NAK leather is waterproof, simply run the boot under the tap to clean it up after a long day of riding.
