STRATFORD, Ont. - A shoe worn and autographed by pop star Justin Bieber has sold on eBay for US$1,425.

The 17-year-old singing sensation from Stratford, Ont. donated his purple Nike sneaker to help out his former high school.

Stratford Northwestern Secondary School put the shoe up for sale to raise money for a broadcasting studio.

There were 38 bids submitted for the scuffed, size 7 1/2 right shoe before the auction closed at 5 p.m. on Sunday. The identity of the winning bidder is unknown.

The school has not decided what to do with the left shoe yet.

The sneaker was first sold for US$5,500 on eBay last month, but the sale fell through after it was revealed that an Edmonton girl had placed the bid without asking her mother first.
