This collaboration model with ADVANCED RESEARCH, a Berlin-based curation platform, is based on OAO's popular "SHELL" model and has been redesigned to reflect ADVANCED RESEARCH's pursuit of culture and aesthetics. Paying homage to the journey of an Edo-period poet exploring Japan's beautiful nature and art, the shoes incorporate the colors, patterns, and textures of clothing and travel gear seen at the time, blending a distinctively Japanese aesthetic with modern technology. The ADVANCED RESEARCH logo is attached to the side flap.

The original SHELL structure, including the split instep and Velcro leather flap, has been inherited, making it easy to put on and take off, and providing an easy fit and comfortable wear.
