Former professional basketball player Shaquille O'Neil's shoe size is 22, which means his feet are 16 inches long. Shaq retired in 2011 after playing for six different teams including championships with the Los Angeles Lakers and finishing with the Boston Celtics.
During his career, Shaq became the face of Reebok. After a confrontation with a mother who wasn't impressed with the price of sneakers on the market, he started making affordable shoes under two of his brands, "Dunkman" and "Shaq." Over 80 million pairs of shoes were sold through discount shoe companies like Payless Shoes.
Shaq's other career highlights include MVP awards, double-digit appearances in all-star games and an estimated career earning of $292 million. He was making $19 million in endorsements by the time he was 23 years old.
