Yes. Paul pierce had some kids shoeline that no one really remembers, rondo had a players edition of hyperdunks or huperfuse, and kg had some shoe line in China from anta. But none had a full blown shoe line and clothing line from Nike. Kyries shoeline is very high selling
Also to note, kyrie is very popular on social media. More ig followers than Durant, Curry, cp3, and a lot of players. He has 10 million instagram followers. That's 12 times as many followers as rondo. More followers than many famous actors and celebrities actually. 1 million, let alone 10 million is no easy feat even for celebrities
I prefer the style of kyrie shoes compared to other players. durant and Kobe shoes tend to not have any ankle support, and the style isn't nice. Lebron shoes have 40 straps and are heavy. The kyries are simple but nice
