Hey, I'm confused about the following sentence:
「おおおお！くつはこのまえ新しいの買ってもらった！」
[On the page before, the girl asks about her shoes.]

I'm guessing it means kinda like:
"Aaaaah! These shoes are recent, new ones were bought for me"

Though I think I'm wrong so yeah.
Is このまえ modifying 新しい here? What's the purpose of the の in the sentence? I took it as it being もの.
