젖은 comes from the verb 젖다, which means to get wet / to be wet.

Here, 젖은 운동화 means wet sneakers or more literally sneakers that have gotten wet. Korean often uses the adnominal past form (-은 / -ㄴ) to describe a noun that is in a resulting state.

So:

• 젖다 = to get wet
• 젖은 운동화 = sneakers that are wet / sneakers that got wet

젖는 운동화 would sound like sneakers that are getting wet or sneakers that tend to get wet, which is not what is meant here.

운동화 specifically means sneakers, tennis shoes, or athletic shoes.

It is more specific than 신발, which is the general word for shoes/footwear.

So:

• 신발 = shoes (general)
• 운동화 = sneakers / athletic shoes

In this sentence, using 운동화 gives a more concrete image: the person is wearing wet sneakers.

In Korean, the verb for wearing changes depending on what you are wearing.

Common ones:

• 입다 = wear clothes
• 신다 = wear shoes, socks
• 쓰다 = wear a hat / glasses sometimes in older usage for masks, etc.
• 끼다 = wear glasses, rings, gloves
• 메다 = wear/carry a bag on the shoulder

So:

• 운동화를 신다 = to wear sneakers
• 운동화를 벗다 = to take off sneakers

English uses wear for many things, but Korean splits this into different verbs.

신은 채로 means while still wearing them or with them still on.

The pattern -은/ㄴ 채로 means:

• in the state of having done something
• without changing that state

So here:

• 운동화를 신다 = to wear sneakers
• 운동화를 신은 채로 = while still wearing sneakers / with sneakers still on

This is stronger than just saying the two actions happen together. It emphasizes that the person has not taken the shoes off yet.

Yes, but the nuance changes.

• 신고 = wearing, and...
• 신은 채로 = still wearing, in that unchanged state

So:

• 젖은 운동화를 신고 방에 들어오지 말고...
  = Don’t come into the room wearing wet sneakers...

• 젖은 운동화를 신은 채로 방에 들어오지 말고...
  = Don’t come into the room with your wet sneakers still on...

The version with 채로 feels a bit more emphatic about the unwanted state remaining unchanged.

Also, grammatically, 채로 needs an adnominal form like 신은, not 신고 채로.

-지 말고 means don’t do X, but instead do Y.

So:

• 들어오지 말고 현관에서 벗어
  = Don’t come in; instead, take them off at the entrance.

It is made from:

• 들어오다 = come in
• -지 말다 = do not...
• -고 = and / and then / but rather

This pattern is very common in commands:

• 거기 앉지 말고 이쪽으로 와.
  = Don’t sit there; come over here.
• 혼자 하지 말고 나한테 말해.
  = Don’t do it alone; tell me.

So 말고 often has the feeling of not that — do this instead.

들어오지 마 is a complete command by itself: Don’t come in.

But this sentence continues with another command:

• 현관에서 벗어 = take them off at the entrance

So 들어오지 말고 is used to connect the first command to the second:

• Don’t come in, and instead take them off at the entrance.

If you said:

• 젖은 운동화를 신은 채로 방에 들어오지 마. 현관에서 벗어.

that would also be correct, but it would sound more separated into two short commands.

The object 운동화를 is omitted because it is obvious from context.

So the full meaning is:

• 현관에서 운동화를 벗어
  = Take off your sneakers at the entrance.

Korean very often drops things that are already understood, especially:

• the subject
• the object

In this sentence, the understood subject is you, and the understood object after 벗어 is the wet sneakers.

Because 에서 marks the place where an action happens.

Here, the action is taking off the shoes, and that action happens at the entrance.

So:

• 현관에서 벗어 = take them off at the entrance

Compare:

• 방에 들어오다 = come into the room
  Here 에 marks the destination.

A useful way to think of it:

• 에 = to / at / in as destination or location
• 에서 = at/in a place where an action is performed

So in this sentence:

• 방에 = into the room
• 현관에서 = at the entrance (where you take them off)

방에 means into the room.

The speaker is specifically saying not to come into the room wearing wet sneakers. That may imply:

• the speaker is already in a room
• the room floor matters specifically
• the speaker is warning the person before they step further inside

If the speaker wanted to mean the house more generally, they might say:

• 집에 들어오지 말고 현관에서 벗어.
  = Don’t come into the house; take them off at the entrance.

So 방 is more specific than 집.

벗어 is a casual command form.

It would be used toward:

• a child
• a close friend
• someone younger
• someone you speak casually with

It is not polite in formal situations.

More polite versions would be:

• 현관에서 벗으세요.
• 현관에서 벗어 주세요.

So a more polite full sentence could be:

• 젖은 운동화를 신은 채로 방에 들어오지 말고 현관에서 벗으세요.

The original sentence sounds natural in a home setting, especially if someone is being told directly not to track water inside.

Yes. It sounds like a direct, practical household instruction, and it can also feel a little scolding depending on tone.

The speaker is not just stating a rule. They are reacting to a situation:

• the sneakers are wet
• the person is about to come in
• the speaker wants them removed immediately at the entrance

So the feeling is something like:

• Don’t come into the room with those wet sneakers on — take them off at the entrance.

The grammar adds to that nuance:

• 신은 채로 = still wearing them
• 말고 = not that, do this instead
• 벗어 = direct command

So overall, it feels immediate and practical, not neutral or bookish.
