The Ultra Boost is the shoe that put Adidas back onto the map, in 2015. The technical detail that separates Ultra Boost from other shoes is Boost, a proprietary sole technology that offers higher comfort for running. But it’s cultural impact and product success came from the fact that it was one of the first running sneakers that looked as good, with its minimal colors and sleek silhouette, as it performed in running and felt to wear. With a combination of clever marketing and celebrity hype, it’s no surprise that Ultra Boosts quickly moved beyond sneaker heads and into the mainstream.
