"Hij draagt de schoen niet" (above; he wears the shoe not)
"Hij draagt schoenen niet" (he wears shoes not)
"Hij draagt geen schoen" (he wears no shoe)
"Hij draagt geen schoenen" (he wears no shoes)
which ones are acceptable in Dutch?
I have read the "Grammar: 'niet' and 'geen'" post (https://www.duolingo.com/comment/3734833) but am still a bit confused.
Only #2 is not correct Dutch, although if you put de before schoenen in that sentence, it would become perfectly acceptable Dutch.
