Melian Snake Skin Boots

Melian Black/Grey Snake Skin Boots with buckle detail. Size 7-1/2 B. Bought a few years ago and worn about a dozen times. Bought thinking they were snake skin but I don’t see any markings stating this. Soles of boots are leather and the almost 4” heals have added detail. There are glue markings on the inside zipper of the right boot (see pics).
