What to assume when a listing just says "leather" and leaves it there.
This isn't a material of its own — it's what shows up on a listing or a care tag when the maker just writes "leather" without saying which kind. That's not necessarily a red flag; plenty of everyday, non-exotic boots are described this plainly, especially older pairs or ones from smaller makers who don't break out the detail the way a big brand's product page might.
If nothing else is specified, cowhide is far and away the most likely material — it's the default leather in boot making by a wide margin, covered in full on our Cowhide entry. If the boot has any texture, sheen, or weight that doesn't match what's described there, it's worth asking the seller directly which leather it actually is before assuming.
If you're buying for resale, insurance, or just because you care about getting the material right, an unspecified "leather" listing is reason enough to ask. Reputable sellers can usually tell you more once asked, even if the original listing didn't say.
