The New York City flagship — located at 565 Fifth Ave. on the corner of 46th Street — takes up more than 45,000 square feet of real estate throughout its four floors, with levels dedicated to men’s footwear and apparel, a Launch Zone, women’s footwear and apparel, and a level for Adidas Originals and young athletes. The store is special for Adidas for multiple reasons. For starters, it’s the athletic giant’s largest store in the world. It also introduces a stadium retail concept, which is inspired by high school stadiums and designed with the culture of sport in mind. To execute the concept, Adidas welcomes customers through a tunnel entrance. There are stands to resemble live-game viewing, and the store features locker rooms rather than dressing rooms. But to really nail the theme, the brand built a track and a turf section for customers to wear-test product.
