Wildsmith Model 18 rubber-soled boots in Black Calf - Wildsmith Shoes. An elegant Derby boot with subtle diamond brogueing across the toe-cap, Model 18 is a classic Wildsmith piece benefiting from a modern update with the rubber stud sole and comfortable padded insole. The Derby lacing makes this easy to get on and the heel-pull gives you extra purchase if you need it. The Wildsmith brand has been around since 1847 and this heritage is a strong influence to the modern interpretations we are proud to be stocking.
