Hopper Buckle Boot in Black Calf The Grand Collection boot last has been refined by our Atelier, testing with direct feedback from the most discerning bespoke international clientele. Inspired by free spirits, for a life well lived, the "Hopper" is named after counter-culture figurehead Dennis Hopper. Hand polished black calf brings a quiet sophistication to everything from navy suits to cream wool, making this the perfect office choice.
