cause they just do

Well it probably depends on the space boots are heavy, but about millions of years.
Styrofoam cups last in the landfill for hundreds of years. Paper cups break down much faster. Paper would only last for a month.
nonbiodegradable waste can last for hundreds even thousands of years.
Until something disturbs it, like a future meteor impact, or a future moon landing. The footprints left by the astronauts may last millions of years.

I expect that the figure you provide is wild speculation on someone's part, but footprints would most likely be destroyed either by an asteroid or comet striking the moon or a moonquake.
hundreds of years. Alcohol doesn't degrade with time.
There were recent amazing pictures released to the press of the surface of the moon which showed many of the objects left on the moon including footprints! So you know the footprints last over 40 years because it has been that long since Neil Armstrong made history with the first footprints on the moon.

Scientist from different nationsintentionally crash objects into the moon for various studies.
