The gun impacts on the hard plastic floor board and it thunders out. The bullet tears the gun out of the officer's hand and sprains his wrist. He falls to his knees and holds his swelling wrist. You just get out of the jeep and run like a bastard with a snarling pit bull about to bite his ass. Both of your shoes make this wild POP! and suddenly you are running much faster then you ever have ran before.
Some mechanism in your shoes is lunching you forwards like a rocket. You fear you may fall and roll into something hard. You're going too fast to see it, but smoke rises from your feet as you go.
