Black and Brown Corso Como Riding Boots Sz 8

Beautiful tall black boots with a brown accent at the top. Feels like leather, but I can’t find a materials marking. Some scuffs on the toes, and a mark inside one of the boots (as pictured). The soles are in great shape. I love these, but they don’t fit my big calves! Shaft is 12”, heel is 1.25”. Shaft is 14” wide at the top.
