Choripán is a type of sandwich popular in South America. The name comes from the combination of the names of its ingredients: a grilled chorizo (sausage) and a pan (crusty bread).
Luciano Guzman came up with the idea of ChoriVans at a barbecue. He made the sketch in Photoshop that looked very cool and made the final at the Vans Argentina shoe company's "Classic Buenos Aires." Then he had to figure out how to execute the design. He cut the sneakers down the middle and assembled a shoe sandwich with bread and sausages.
