This is a special edition of the 580 made exclusively for mita sneakers in Japan.
It was released in 2014 as a Japan-exclusive, so it’s quite rare.
Though it’s all white, the crocodile embossing and cross-patterned texture make it simple yet highly distinctive.
The design is excellent and very stylish.
Considering its age, the condition is quite good.
*The first image is just for a reference.
