Some people love a fine wine, others a good book or movie and a certain segment of the population is obsessed with shoes.

This is made evident by the fact the line outside the Niketown in downtown Seattle was already forming Friday morning—more than 24 hours before the release of a new, limited edition Air Jordan sneaker.

The Air Jordan IV Retro Doernbecher will go on sale at 8 a.m. Saturday.

The shoe, named for the Doernbecher Pediatric Hospital in Portland, was first released in 2004. All proceeds from the shoes go to the non-profit hospital.

The Air Jordan IV Retro Doernbecher, designed by Isaiah Scott, is the eighth Doernbecher to be released.

“This extraordinary program has raised over $3 million for the hospital, which uses the funds for everything from clinical programs and hospital construction to providing care for uninsured children,” the Nike Store said in a statement. “This year's patient designers come from Doernbecher's cancer, neurosurgery, cardiac surgery and nephrology programs.”

As of 11 a.m. Friday, a line of approximately 20 people had already formed outside the Seattle Niketown.
