The original pair is supposed to be a red Nike.

Maybe it's because Nike does not approve their trademark to be used on this item. ^^;
Maybe the initial delay of release was due to this as well. Bandai might had better luck if the company approached Adidas instead? XD
Late February release, 5,775 Yen (inclusive of tax).
