"I am not wearing boots, but sandals."

Translation: Nem bakancsban vagyok, hanem szandálban.

[Evolita]

Nem viselek bakancsot hanem szandalt - should be accepted as well. Reported it. Boots also means "csizma" in Hungarian so there is another word to insert.

[vvsey]

The word order is a bit unnatural. Either "Nem bakancsot viselek, hanem szandált" or "Nem viselek bakancsot, hanem szandált viselek/hordok". Yes, with this word order, I would repeat the verb (or use another verb). The reason: whatever is negated in the first clause has to have its complete matching counterpart in the second clause.

• Nem bakancsban vagyok - "bakancsban" is negated. Hence, "hanem szandálban" is sufficient.
• Nem viselek bakancsot - the whole "viselek bakancsot" is negated. Therefore, "hanem szandált hordok" is the counter-statement.

[KlaraBerna1]

you can also say nem vbakancsot viselek, hanem szandált.

[ljikontic]

I suppose that the bakancs is a big shoe and the boots are famous Hungarian ''piros csizma.These words I know from my neigbourhood, Hungarians

[Evolita]

Bakancs: hiking boots, construction workers' boots. Those "piros csizsma' are more like cowboy boots actually... close enough

[ljikontic]

I am sure that the bakancs can not bee a boot,and the csizma is a boot.Even in Serbian we use that word bakancs in the meaning of a winter shoe and workers shoes

[RoNagyCacao]

Are "bakancs" and "szandál" always used in the singular?

[KlaraBerna1]

I think it is an ongoing thing: to wear has many synonyms , I used "hordok" which is also fine
