まず、「靴を履いている」と言うときは "shoes ON" オンを使います。
履いた「まま」と言いたいときは"keep" "leave"どちらでも通用します。
それらを繋ぎ合わせて
Can I keep my shoes on?
Can I leave my shoes on?
というフレーズに成っています。
聞き方を少しかえて、「靴は脱がなくてはだめですか?」と聞くのであれば
"Do I have to take off my shoes?"
と聞けばOKです。
☆まとめ
脱ぐ=take off
履く=put on
履いたまま=keep on/leave on
Leave という動詞は残すという意味なので leave my shoes on は 「靴を履いたまま」
という意味になります。同じパターンで
Can I keep my shoes on?
も使えます。
もし脱ぐ必要がありそうでしたら逆に
Should I take my shoes off?
靴は脱ぐべきですか?
と聞く手もあります。

We can use the verb, "to keep," as a way to ask if the shoes can stay on or to describe that something will remain the same.
We can also use, "to allow," to refer more to our permission and if sometimes is ok for us to do.
We can also reverse the sentence with, "to have to take off," rather than asking if we can, "keep on," something.
