React Presto x Undercover Worn a few times, but I took good care of them, so there are no noticeable stains or damage. There is a tiny spot of dirt on the front, but please understand that this is a used item before purchasing. The React Presto 'Nike x Undercover' continues to express Jun Takahashi's vision of chaos and balance. It combines the classic style of the Presto with design details inspired by the previous React Boot, born from the collaboration between Undercover and Nike.
