You mean the I-5923 or whatever
adidas was going hard after a lot of icons (Drake, OBJ, there's another big Nike name that slips my mind right now) and when a lot (all) of them fell through, they had nothing new/exciting to bring to market. Just had to keep dropping UBs and NMDs and 350s. Kanye was like the rocket ship and then they ran out of fuel. adidas has a huge issue too with focusing too much on designing lifestyle shoes. There isn't a story behind a lifestyle shoe. Athletes are huge parts of the story. Stan Smith, Superstar, hell nobody cared about Boost until Kanye wore it. There's no athlete/icon behind NMD, Deerupt, Propheres, Nite Joggers, many others... shoes that didn't have history behind them (ex. Trae Young dropped 47 in these, Tyler the Creator wore these when performing at the Grammys, etc.). When Kanye was the culture, they springboarded to relevancy but when Kanye had his issues near the end of 2016 that was the beginning of the bell curve heading downward.
