So I came across kõpsikud in a book I was reading. I know that means some kind of shoe/footwear. (That's why I was going to post in the thread Sõnad, mida hiljuti õppisid - I've learned at least that much about what it means.)
But, I'm not sure how specific it is (footwear in general? women's heels?), and I can't find it in any of my dictionaries.
The plural is kõpsikud, I suppose the singular should be kõpsik, but I've only encountered the plural.
Well, in the context where I found it, it seems to mean a woman's high-heeled shoes, and a google search comes up with photos of those as well.* So I don't know if it refers only to high-heeled shoes, fancy shoes, shoes that make a kõps-kõps-kõps sound (I suppose that would be women's heels too), or footwear more generally.
These are kõpsikud:

It's not really important for me to know what it means other than "some kind of footwear" and I suspect it's the type of women's heels that make a loud noise or ones similar to that, but I'm rather bored right now and unable to post in other threads at the moment, so... this post happened.

*The google search came up with several examples of "kõpsikud jalga," which seemed encouraging, but then, as if placed there purely to confuse me, also an example of "kõpsikud ninna".
