If you can't compete in the Olympics, the next best thing may be designing sneakers and apparel for Olympic athletes.
Tobie Hatfield, senior director for athlete innovation at Nike, is doing just that. For more than 26 years, Hatfield has been helping design and innovate products for some of the best athletes in the world.
"When they are going across the finish line, ... I feel like I'm going along with them," Hatfield told CNBC.
The designer has created key innovations for athletes, like decathlete Ashton Eaton, pole vaulter Renaud Lavillenie, high jumper Erik Kynard Jr., triple jumper Christian Taylor and sprinter Allyson Felix.
When it comes to innovation, Hatfield takes his job very seriously and believes his product's performance can really make a difference. "In track and field for instance, really the spikes are the only equipment they have out there," he said.
Hatfield has the unique challenge of designing products that work not just for Olympic athletes but that also translate to the rest of us. Many of the items athletes are wearing are already available at retail.
