Diego Costa's "Customized" Adidas X 15.1 Primeknit Boots
Whereas the standard Adidas X 15 Primeknit cleats feature a small techfit collar, Costa decided to get rid of this part of the boots completely. Apart from that, Diego Costa's Adidas boots are identical to the regular edition, although he laced them up in a different way than usual, ignoring the lace tunnels in the middle of the tongue.
