CORPUS CHRISTI - If some of your old flip flops have seen better days, you don't have to throw them away. Instead of flinging your filthy flip flops into the garbage, you can bring them to Old Navy to be recycled. From now until May 21, you can toss your old rubber flip flops in a bin, putting your old shoes to good use. Terracycle and Old Navy are working together to turn those flip flops into four playgrounds around the country. "That one flip flop is going to be a playground, it's going to be a swing, it's going to be some part of some other kid's life," said store manager Paul Carrion. Giving new life to shoes that may have ended up in a landfill.
