SAN DIEGO – A little more than 200 San Diego teens have broken the Guinness World Record for donating the most shoes in 24 hours. The volunteers worked day and night Dec. 7 to unload thousands of boxes of shoes and give them out to folks in need for the holidays in a parking lot at the Sharp Spectrum Center in San Diego. By 6:30 a.m. the parking lot was filled with families awaiting the 8 a.m. start time.
