Are goat shoes real?

Could you please clarify for me, are goat shoes indeed an authentic and viable footwear option, or is this merely a colloquial term used to describe a particular style or brand? Are they constructed primarily from goat leather, or is there some other distinguishing factor that sets them apart from other types of shoes? I'm genuinely curious about the authenticity and specifics of this footwear, and I'm hoping you can provide me with a definitive answer.
