Shoe fans aTwitter in dash for Jimmy Choos

Shoe lovers in London have been glued to their mobile devices and computer screens in a race to win a pair of free Jimmy Choos.

The Jimmy Choo trainer hunt or "CatchAchoo" race offers the winner the chance to keep a free pair of the shoes so loved by celebrities if they can figure out where they are in London according to clues left on social networking sites Twitter, Facebook and foursquare.com.

A picture of a Jimmy Choo bag is taken in the location and left on the sites, where a company representative will wait for a short period of time with the shoes on display.

Those who have figured out the clue must race to the location, approach the representative and say: "I've been following you" to win the shoes.

The competition, which has been running since April 19th will carry on until someone wins the prize.

"There have been some close shaves when people have missed the shoes by a minute or two. But it triggers the motivation to catch them next time," a Jimmy Choo spokeswoman said.
