Tiger Woods has been golfing professionally since 1996. Since then, he has exclusively worn Nike shoes. Especially on the field. He signed an exclusive partnership with the athletic brand and began wearing their products as soon as he stepped onto the professional course.

Tiger's first contract with Nike in 1996 (reportedly for $40 million over 5 years). According to a 2013 ESPN report, this was followed by an estimated $100 million contract signed in 2001 over 5 years, and then an 8-year deal in 2006 for an estimated $20-40 million annually.

'I needed something that allowed me to be more stable' “I have very limited mobility now,” Woods said. “Just with the rods and plates and screws that are in my leg, I needed something different, something that allowed me to be more stable. That's what I've gone to.

Woods initially signed with Nike for a five-year, $40 million deal in 1996. Once that deal expired, Woods inked a five-year, $100 million deal with Nike in 2001.

“Its a very competitive business, and Nike sticking with Tiger shows how they value relationships.” Woods' winning streak in the 1990s and early 2000s sparked a boom in the sport.

In 1996, that all changed. After Woods won a tournament at Pumpkin Ridge right outside of Portland, Phil Knight and company came ready with an offer they'd been working out for months: a five-year contract worth $40 million.
