Wearing cleats is helpful.
When you run really fast you can help your team "set up" for a 2nd and short in football American.
Why do you bother? You aren't on a football team nor will you ever be.
Typically, flat-out sprinters run differently than other athletes who do football (or other running related sports). The goal of sprinters, like Usain Bolt, run in a straight line with they're feet moving forward. However, football players have a wider stance and kind of move side to side. It's like sprinting normally, but with your feet further apart, forcing you to sway a little. you can still run incredibly fast like this, but will also allow you to switch directions very quickly
