That's the Prestwick boot. It's a nice boot. Comfy. I've seen some new ones on the bay from time to time. I would ask a cobbler to put on a "Vibram Christy wedge sole". I say they would charge $50-75. They would remove the old sole. Sand it down and glue the vibram to it. Better that they have the sole in stock. If not, they would have to order it. May cost more $$$.
