With all of the reports of Kanye’s Adidas deal, the #StanSmith pop up might’ve been overlooked by many-

To celebrate the famous sports shoe named after American tennis icon Stan Smith 50 years ago, Adidas opened a pop-up store in London that was a scale replica of the iconic footwear’s shoebox. Apart from being able to purchase limited edition shoes, customers were also able to take part in an interactive experience which made use of 3D-printing.

3D Systems Cube printers lined the walls and gave customers a chance to personalize their lace locks. One of the most notable experiences was the ability to “Stan yourself,” a preview of an app by the same name that allows users to put their own portrait and signature in the place of Smith’s portrait and signature.

More than 40 million pairs of Stan Smiths have already been sold, making it the top-selling brand in the history of Adidas. Unlike the usual experience of going to buy a pair of shoes however, the sports brand made sure to give their customers an experience they are unlikely to ever forget.
