Y’s will release the second collaboration with Flower MOUNTAIN on Wednesday, April 15, 2026.
This collaboration silhouette is designed based on Flower MOUNTAIN’s footwear “PUMA PUNKU,” known for its nature-inspired forms and handcrafted processes. Following the model released last year, this second edition is introduced with updated colorways. It is available in two colors: blue and black.
Compared to last year’s model, the adjustable range at the heel has been expanded to achieve a more stable fit. An insole with excellent cushioning and resilience, combined with a lightweight sole offering high grip, provides a comfortable wearing experience.
Flower MOUNTAIN’s signature multicolored expression is reinterpreted in a “monochrome” approach, creating depth through variations in texture and tone produced by combining multiple materials. The construction features shrink leather, hair-on leather, and nylon.
The original perforations across the upper have been removed, while details such as the materials and specifications of the lace tips and heel elastic have been refined, incorporating a more sophisticated expression. The center of the instep features the double name “Y’s” and “Flower MOUNTAIN,” while a woven “Y’s” logo label is placed on the side.
The delicate handcrafted finishing of Flower MOUNTAIN enhances its unique expression and texture.
Y’s × Flower MOUNTAIN will be released in advance nationwide at the pop-up store at Isetan Shinjuku starting Wednesday, April 8, 2026. Pre-orders will be accepted on the official online store from April 8 (Wed) to April 12 (Sun). The collection is scheduled to be available from Wednesday, April 15 at the official online boutique and all Y’s stores across Japan.
