just yesterday (evening) i got a knitting book with sock and sweater patterns. It's printed by a german company, in german, french, italian and english.

they call the men's socks (in italian) calzini da uomo(sock for men) and they call the childrens knee socks--calzettoni

perhaps there are several terms for socks (in italian)

socks (english) is obviously from a german word--mens socks are Herrensocken and knee socks are kniesocken--

but we also use the term stocking, and hose, and hosiery, and leggings. and sox is not unknown either!

there is footwear as well as shoes, --and boots, and mules, and moc's, and lots of other words for the stuff we wear on our feet. some terms more generic, some more specific.
