OAO MADE IN JAPAN PRODUCT.
A pair carefully handcrafted by shoe artisans in Asakusa, Tokyo.

Made of Tochigi leather nume hide, renowned as one of the finest leathers produced in Japan. Using a full vegetable tanning method with mimosa and no chemicals at all, each hide is finished by an artisan, giving a beautiful, smooth touch and appearance. It ages naturally and in richly varied ways depending on sunlight and the environment in which it is worn.

The sole uses Vibram's rubber trek sole, with voluminous grip and excellent durability. By injecting high-density, highly resilient urethane inside, the model achieves a softness and comfort unprecedented for leather shoes and boots.

Through a study of authentic style, this model aims to balance elegance and functionality in a modern context. The upper adopts a classical, bespoke-inspired pattern.

*Nume leather is tanned with plant-derived natural materials, and is a one-of-a-kind leather finished as-is, without using pigments to conceal the natural character of the hide. Please note that there may be uneven coloring, scratches, or blemishes inherent to the leather at the time of delivery. It ages with use and care, and scratches tend to blend in over time. As it is sensitive to water and stains easily, please avoid wearing it on rainy days.

SIZE SUPPORT suggests sizes that are suitable for your feet.

PU & RUBBER
The entire surface is made of high-quality rubber from Vibram, which has excellent weight, anti-slip properties, and abrasion resistance. The midsole incorporates a soft cushion made of polyurethane, providing a comfortable fit that does not depend on the appearance.
