Flex your creative muscles while helping The Fresh Air Fund by purchasing the Friendship Shoe at Payless. The white, canvas slip-on comes with a set of markers for decorating, and 100% of the profits will be donated to help inner-city children vacation in the country. Not only do they help a great cause, but the shoes are also perfect for commemorating various occasions. Pass a pair of these around at your graduation party/birthday/wedding shower/family reunion, and you'll be delighted by all the signatures and decorations you amass. Consider it like a cast-signing, without the tedious process of breaking a bone. The shoes are just $17.99 and are available until July.
