15-year-old boy shot in leg waiting to buy sneakers in Brooklyn

A 15-year-old boy waiting in line for a new pair of sneakers was shot outside a Foot Locker store in Brooklyn early Saturday.

The boy was shot in the leg on Knickerbocker Avenue near Stanhope Street at 5:40 a.m., cops said.

The shooter next fired at the victim’s pals, who chased and stabbed the gunman, law-enforcement sources said.

Police are questioning a teen with a stab wound who later showed up at Woodhull Medical Center — the same hospital where the shot kid was being treated, sources said.

“People were screaming and scattering all over the place,” recalled a 15-year-old witness who asked to be identified only as “Robert.”

Sneakerheads had been waiting for the $150 Air Jordan 11 Low “Green Snakeskin” and the $250 Nike Air Foamposite Pro “Yeezy” kicks.
