This promises to be a really big shoe.

Memorabilia house Gotta Have Rock and Roll is hosting a celeb shoe auction to benefit the city's Fiorello H. LaGuardia High School of Music & Art and Performing Arts. The fun begins Wednesday at gottahaverockandroll.com with these highlights (all come with a certificate of authenticity):

SARAH JESSICA PARKER Fashionistas unite with three pairs of shoes from the Carrie Bradshaw days: Prada platform sandals, Dolce Vita pumps and Jonathan Kelsey sandals.

BRITNEY SPEARS The pink platform shoes go back to 2000's "Crazy" tour, and they come with a letter from Brit herself.

SHAQUILLE O'NEAL "Southland's" special guest star a few weeks ago offers up a pair of his size 22 kicks from when he played (briefly) with the Miami Heat. Shaq even signed them.

Other celebrity-worn and donated shoes will come from the likes of Madonna, Janet JacksonMiley Cyrus, Ke$ha and more. You've been warned if this sort of thing appeals to your sole.
