"He buys a bag, a pair of shoes, and a wallet."

Translation: Dia membeli tas, sepatu, dan dompet.

The word "a pair" was not told. We don't say it?

Halo teman! I think "sepatu" is more colloquial. Even when talking about "several pairs of shoes" , "several shoes", or just "shoes", one could (I think) just say "sepatu", and to be more explicit, "sepatu-sepatu". When the grammar speech is more strict, or necessarily formal, then I think "a pair of shoes" would be "sepasang sepatu", where "sepasang" is formed by "satu" + "pasang", "one" + "pair".

I hope it helps.

Selamat belajar! :)

Because I translated it exactly from English to Indonesian.

"He buys a bag, a pair of shoes, and a wallet."
Dia membeli satu tas, sepasang sepatu, dan satu dompet
