A collaboration between Wacko Maria and Vans is reportedly in the works, with some outlets suggesting a Japan-exclusive Authentic shoe. The design details are unclear, with some sources mentioning a "Paisley" or "Leopard" theme, while others do not specify. It is also uncertain if this is a standalone release or part of a larger collection, as some outlets mention unrelated collaborations, including one with Converse and another with BABYMETAL.
