How long do you actually have to stop yourself from spraining your ankle?

About two seconds. That's the window when your body's proprioceptive system registers something's wrong and can activate stabilising muscles to pull your foot back to a safer position—if your reflexes and muscles respond quickly enough.

Do hiking boots actually prevent ankle sprains?

Not really. No boot can stop you from landing awkwardly on uneven ground or prevent a sprain if the forces are significant enough. What boots can do is provide better traction and fit, which helps with initial contact and your ability to recover.

Does being tired make you more likely to twist your ankle?

Yes, fatigue slows down your recovery response. Those stabilising muscles that might save you when you're fresh don't fire as quickly or strongly after six hours of walking, and your proprioception gets woolly, making that two-second recovery window narrower.
