Greg Woodburn, a student at the University of Southern California, spends a lot of time cleaning once belonging to others. Soon the shoes will have new owners: underprivileged children in the United States and 20 other countries, thanks to Woodburn's Share Our Soles (SOS) charity.
A high school track star in the beach town of Ventura Woodburn was once sidelined for months with food injuries.
"I started thinking about all the things I got from running -- the health benefits, the friendships, the confidence," he says. "And I realized there are children who don't even have shoes."
Woodburn gathered up his own slightly worn sneakers, and then put out a call to teammates. His goal was to have 100 pairs by Christmas 2006. When the count climbed to more than 500 pairs, ("everything snowballed" he says) he decided to turn the shoe drive into a year- round effort.
Back then, the sneakers came from donation boxes mad the local sporting goods store and from door-to-door pickups. Woodburn has now set up collection boxes at two high schools and area races. To date, SOS has collected and donated more than 3000 pairs.
In just under three years, Woodburn has started three chapters of Share Our Soles: the original in Ventura, another at USC, and one at the College of the Holy Cross in Massachusetts last January, when a student there wrote asking to get involved. The organization's website, shareoursoles.org, keeps and distributes sneakers and sells wrist bands and socks (the money earned from that goes toward new shoes and socks for children).
