Why do the newly brushed sneakers have an unpleasant smell?

Problem description:

Why do the newly brushed sneakers have an unpleasant smell? That's disgusting. I don't want to wear those shoes now, but it's too bad. What should I do with it? Thank you! ! !

Analysis:

Just like not using a wet mop for a long time. See the water will have such a taste? The best way is to apply leather care oil and put it in a dry place. If it really doesn't work, just dry it in a place where the sun is not too big, and just put some dehumidifying deodorant in your shoes.
