As we all know the Player Exclusive versions of signature sneakers are customized to satisfy players’ individual expectations. However, you might don’t know that even such details as insoles of the shoes are personalized to meet the requirements of the athletes. Below you can see a Zoom LeBron IV insole from one of the Player Exclusive sneakers. As you can see a carbon spring plate has been added on the bottom and the upper part is made entirely from leather. Photos thanks to H-Leung from hk-kicks.com.
