Ok ok ok, this is sooo gross , I am having suspicious thoughts that it might be that the balcony door downstairs has been open sometime and humidity has come in the house and since my wardrobe is upstairs … the hot air from outside might have gone to my wardrobe and the humidity has stuck on some of my shoes … then when it is dried it has collected dust and this is the results of what I’ve seen? Thoughts !? Or do we have some disgusting mold in the AC system !?? It’s the only thing I can think of . Please feel free to eleborate in the comments below !

Ansywahs i have cleaned the shoes hows now and they are fresh as F, yep!
Salute !
