The LEGO x adidas Ultra Boost 4.0 released on April 8, 2021, for €160. One store opened its drop at 10:00, while another went live at midnight. The pair was part of the ongoing partnership between adidas and LEGO, which had already produced a ZX 8000 in 2020. The Ultra Boost first launched in 2015 and became one of the most popular adidas running shoes. A style code and the official colorway were not listed in the release information. Second chance options were collected on the release page after the drops. Today, the LEGO x adidas Ultra Boost 4.0 can be found on marketplaces such as KLEKT.
