So ladies, if you are in to scavenger hunting to get some free Jimmy Choo trainers, then your in luck. Jimmy Choo has launched just such a hunt, or game, in London using Foursquare. A pair of Jimmy Choo trainers will turn up in various locations around the city. If you catch up with them on Foursquare before the trainers leave for their next destination, you'll win a pair to keep. If nothing else, this is a smart brand awareness campaign. We'll be seeing more of this from other brands.
