When Lonzo Ball strutted onstage at Barclays Center on Thursday night after learning he’d been picked second in the annual N.B.A. draft by his hometown Los Angeles Lakers, he wore a black suit with a shawl-collared jacket, a black shirt, a black bow tie and, on his feet, an utterly garish pair of white submarine-shape sneakers, trimmed in the Lakers colors, purple and gold.

That Mr. Ball was going to be selected by the Lakers was something of a foregone conclusion. Pundits predicted it, and so did his stage dad, LaVar Ball, who in essence told other teams not to consider drafting his son.

Still, nothing is guaranteed. “I’m glad that they picked me,” Lonzo Ball told Darren Rovell of ESPN of his light showboating, “because I didn’t have any other shoes under the table.”

Those statement sneakers were made by Big Baller Brand, the fledgling company that his father founder and that has become something of a basketball world punch line in recent months. It has a sneaker, the ZO2, that sells for $495 a pair, around three times more than an equivalent from a major manufacturer. (A few hundred pairs have sold, LaVar Ball said, though they won’t be delivered until November.)
