The Black Demon walks almost without making any sound, no matter how fast he moves. However, this comes at a price; instead of tactical boots, the Black Demon wears soft-soled boots with very high tops and very thin soles.
Tactical boots are lacking in comfort and are heavy, but they provide maximum protection for the feet. If he were to change into the soft-soled high-top boots worn by the Black Demon just to maintain silence while walking, he would definitely refuse, because then he wouldn't be able to kick doors freely or run and jump on roads filled with broken glass and nails.
The Black Demon's boots resemble high-top canvas shoes, but the soles aren't made of rubber. Gao Yang doesn't know what material the Black Demon's boots are made of, but they look quite impressive.
From a pair of boots, one can see the distinctive feature of the Black Demon's team, which is their extreme emphasis on the silent effect.
