Originally released in June 2018, the Nike EXP-X14 ‘Dark Grey’ sneaker blends design with performance in a neutral colorway. Short for ‘Experiment,’ the EXP pays homage to the Nike Sportswear designers determined to create a lifestyle shoe with innovative performance construction, which would become Nike React foam technology. The lightweight and durable sneaker—inspired by the 1999 Zoom Drive and the Nike Zoom Vaporfly 4%—showcases the inner workings of the design with an exposed TPU plate.
