All hands on decks. For a true sneaker freak, shoes aren't just something to wear on one's feet. As a nod to his obsession with collectors' kicks, Josh Rubin, editor of design blog Coolhunting.com, has created pair-o-deez ($10), a sneaker-themed paring card game based on the age-old kindergarten pastime Memory. Test your recall– not to mention your knowledge of limited edition footwear– with the 52-card deck, which bears photos of 26 pairs of shoes (all from Rubin's personal collection). When you mismatch the Adidas Tennis Hi with the Adidas Nizza Hi, don't feel bitter– 25 percent of the cards' sales goes to the Humane Society Disaster Relief Fund, which helps pets abandoned in the wake of Hurricane Katrina.
