Football boots are for gripping muddy ground and the obvious, which is as shoes that are durable and won't come undone while playing,
Astro boots, are used for playing on astro turfs and hard grass because they give you better grip than, in muddy grass. Normal football boots are generally metal studs which is used for muddy wet grass because they did into the ground and supply you with much better grip than astros would. But you can get football boots with molded plastic studs which can be used for astro turf as well as grass but I don't like using my moulds of astro because it makes you higher off the ground and means it is harder to kick the ball because of the studs :)
Best quality football boots I've owned in 35+ years playing.
