R.L. Stine is going spooky mode for the NBA playoffs. The 78-year-old author and producer, who has sold hundreds of millions of books and whose “Goosebumps” series has a permanent place in the young adult section of many libraries, posted a photo of his brand new pair of “Goosebumps” inspired Kawhi Leonard New Balance sneakers. The sneakers and a similarly-themed t-shirt have been released worldwide for the NBA playoffs.
