Crazy Cow is a leather with real substance. During tanning, the fibre structure is lightly shrunken, creating a tight, durable grain that improves strength and control. At 1.8–2.0mm thick, it has the reassuring weight and support of a boot-grade leather, while still breaking in naturally with wear. It starts off firm, as good leather should, but softens quickly as it responds to movement, gradually shaping itself to your foot while retaining its structure.
