why i can run in heels

Short heels make elite sprinters super speedy: "What is it about elite sprinters that gives them the edge over non-sprinters in the 100m dash? Stephen Piazza from the Pennsylvania State University publishes his discovery, in The Journal of Experimental Biology, that the length of an elite sprinter's heel (the distance from the back of the heel to the ankle) is 25 percent shorter in elite athletes than non-sprinters, allowing them to generate more force when sprinting for gold."
