German sportswear giant Puma AG has come up with a weird and wacky way to promote its new range of soccer boots ahead of this summer's World Cup - by placing them in bamboo and glass display cases in sushi restaurants. The company will place its new Shudoh soccer boots in 15 sushi bars around the world - including Hong Kong, London, Madrid and New York - and will have its name on dinner mates, sake glasses, soy-sauce bowls and chopstick holders.
