British footwear brand Dr Martens has launched a new cross-platform campaign encouraging users to share their first experiences of the brand’s iconic boots.

Topshop, the trendy UK fashion retailer, launched an in-store promotion last week in the UK and Ireland (and this week in New York) backed by one of the hottest mobile apps out there: Instagram.
