I have a pair of lug soled shearling lined Ugg moto boots that are only used for fall-winter-spring commuting. They're great because they're waterproof and I can run for a bus in them. Rain, snow, ice and slush, they've held up. I've had them for about three years. The shearling is worn off in spots in the inside. The heel is starting to wear down a bit. I'm trying to decide if it's worth getting the heels fixed or should I let them die this year and get something new this fall.
