Ever wanted to run like an ostrich? When Keahi Seymour was a teenager, he decided to create shoes that would let him emulate the birds' springy gait and match their top speed—45 miles per hour. Many years and a dozen prototypes later, Seymour came to Maker Faire to show off the latest version of his "bionic boot." This prototype boosts his pace to a brisk 25 miles per hour, but Seymour won't rest until he can take the human body to the next level, and outrun some of Earth's fastest land animals.
