Why Are So Many Of The Olympic Athletes Wearing Bright Green Shoes?

If you were wondering why so many of the track and field athletes at the Olympics were wearing bright green shoes, here's why: they're all Nike athletes. And Nike has decided to go uniform across the globe on bright green shoes to grab your attention.

Known as 'Volt', the shoes are striking against the red track in London. Nike says that out of all the colors on the rainbow, the human eye is most sensitive to the yellow/green zone. That means the Nike shoes the Olympians are wearing reflect more light than nearly anything on the field. The shoes are there to be bright and bold so you look at them... and want to buy them.
