Fast
You jump on your scooter with a big bundle to go as fast as you can! You have a bundle of pizzas in here, and they need to be delivered as fast as you can get them there!
Imagine how fast you can go on your scooter holding this bundle. It's way faster than trying to go on foot, that's for sure!

None
You were going so fast, you only put on socks (そく). So now you're barreling down the street at top speeds in just your sad, white socks.
Imagine riding the scooter as fast as you can in just your socks. You can feel the wind pulling them off your feet!
