A year ago today, adidas introduced a new sneaker, the Ultra Boost, that would change the climate of the company’s sneaker game for the next year. Making a bold claim that they were launching the best running sneaker ever, the Boost technology already had people intrigued. The design, however, was a major upgrade from previous Boost runners in the same family tree, so it didn’t seem like too much of a reach for the brand to make this declaration.

Boost has been around since 2013; it was first created in a laboratory by BASF and started as a technical tool for runners looking for the ultimate ride, while trying to knock out steps for their Fitbits. In 2014, the adidas Energy Boost 2 gave the original model to use the technology even more comfort and also upgraded the aesthetics so you could actually wear them outside of the gym. Boost started showing up in more sneakers, including the Derrick Rose signature line, proving that it was useful for more than just running—and that it was the future of the brand.
