Love them or loathe them, the Australian brand’s sheepskin boots are perennially in demand, a fact that clearly hasn’t been lost on the counterfeiters of the world: 2.5 million pairs of faux Uggs have been seized since 2007. Shoes are the most counterfeited products in the world, with 27,119 seizures in 2013 (the photo shows fake Ugg boots displayed at the U.S. Justice Department in Washington DC).
