Want to run more efficiently? Tie your feet together, say scientists

It used to be that tying someone’s shoes together was a nasty prank, but now it’s a performance-enhancing feat of bio-mechanical engineering. A team of researchers and engineers at Stanford University have developed a radical new method to increase the running efficiency of humans: they put a rubber band between a pair of shoes. This might not sound like a feat of modern technology, but the science behind it is actually quite interesting. According to the team’s research
