Not sure what to do with those old workout/running shoes? Try donating them to Nike's Reuse-A-Shoe, a program that takes primarily worn-out athletic shoes and turns them into Nike Grind material, which is then used to make sports surfaces like soccer and football fields, basketball and tennis courts and tracks. There's no drop-off site here in DC, but you can mail your old treads to:
Nike Recycling Center
C/o Reuse-A-Shoe
26755 SW 95th Ave.
Wilsonville, OR 97070

** The club is likely to organize a group effort to support this or a similar program in the fall. We encourage you to use this known opportunity now, though, rather than waiting. (Anyone interested in organizing a group effort should contact Susan at president@dcroadrunners.org. Thank you.)
