Yeah, really.
Believe me, the first time I heard "pumps" on a US TV programme, I was like "what's that?"
Figured out it was a type of shoe from the context, but it took a good long while to translate it across fully!
I had a similar problem the first time I encountered men's dress shoes being called "pumps." I don't know if they still are - not anywhere around here, I'm pretty sure - but they apparently used to be in the UK and probably elsewhere. I can specifically remember a couple of British books referring to men's "dancing pumps."
You can, perhaps, imagine what picture that created in
my mind. Yes, it involved chiffon, of course...
