The king of collaborations, mastermind JAPAN returns with these new Papillio-produced sandals. Originally an off-shoot brand of Birkenstock, Papillio have established themselves for their comfortable and classic sandals. For this collaboration, mastermind JAPAN have taken the popular double buckle model and used high quality Italian leather for the upper sitting atop Papillio’s patented orthopedic base. The classic mastermind JAPAN logo and skull are embossed on the side of the sandal. Gold buckle and silver buckle versions will be available on the 11th of May with a retail price of ¥29,400 JPY (approximately $347 USD).
