Nike Is Funding This Research and They Have These Shoes

Nike is funding the research and they have these shoes. We had three pairs of shoes in each size that looked exactly the same. And then we didn't just put a beefy mess on it, but we really hit some lead BBs in the tongue of the shoe. There were some double layered shoes where the BBs were hidden. You wear the one shoe the one week and the other shoe the other week and if they're on your feet, you don't necessarily feel a difference. So yeah it worked. People had no clue we were doing this."
