How far can you jump?

Ever wondered if the sport shoe commercials are true? Can different footwear help you jump farther? Better? Higher?  This experiment can help you find out.  Mark a starting point with tape or chalk outside.  Wearing your favorite sneakers, jump as far as you can from your starting point.  Mark where you landed, and label it "sneakers." Now repeat the action in dress shoes, in socks, and in bare feet.  How do your marks compare?
