A glossy, mirror-like lacquer finish — and these days, often not genuine leather underneath at all.
Patent leather is a finish, built up in layers over a base material — historically real leather, but genuine leather-backed patent has gotten genuinely rare, since most modern patent leather is built over synthetic faux leather instead, mainly to keep costs down. The glossy coat itself is applied in three layers: a penetrating base layer, a colored layer, and a hard, transparent, waterproof top coat, using polyurethane or acrylic these days rather than the oil-based varnishes of a century ago. The result is a mirror-like, uniform shine available in essentially any color.
Uncommon in Western boots specifically — it's much more associated with dress shoes — but it shows up occasionally as an accent or on fashion-leaning boots that want that unmistakable glossy look. Worth a close look before buying: on a boot specifically, it's worth asking whether the base underneath the coating is real leather or a synthetic.
Wipe with a damp microfiber cloth regularly, apply a patent leather oil about once a year, and deal with stains promptly since they're harder to lift once set. Keep it out of direct sunlight and heat — the coating scratches easily and will eventually crack with age even with good care, typically within 5 to 6 years of regular wear.
