Why do i run like this? and can i fix it?

first off sorry this is in the wrong category i know, but i wasnt getting any answers in the other category. okay, so whenever i run it sounds like some 500 lb guy is sprinting for a doughnut. and im not even heavy. i just stomp my feet when i run they like....slap down. i can stop it if i do a casual jog but when i sprint its wicked loud. any advice?
