oao SUNLIGHT CORE (BLACK × BLACK) Black Sunlight Core JP 27.5 US9.5 UK9 With box and included card. Purchased from the oao official online store for 55,000 yen. Worn once outdoors. There are no noticeable scratches or stains. I wear 27.5 in Nike and New Balance, and this product also fit perfectly at 27.5. Upper: Cow leather (cowhide) Lining: Pigskin (pig leather) Sole: EVA & Rubber Vibram sole Weight (per foot): 350g Sole thickness (maximum): 4.5cm These shoes are elegantly finished with cow leather characterized by a unique luster and deep grain. Pigskin is used for the lining, providing a snug fit. This model uses Vibram's new Zermatt sole. With a moderate volume of 4.5cm in thickness and a simple design, the sole features "Traction Lug" technology, maintaining soft cushioning while achieving high propulsion and the lightest weight within OAO products. The multiple stitch lines arranged throughout the shoe are designed to correspond to the supple bamboo curves of Isamu Noguchi's light sculpture "AKARI." Traction Lug®️ Through a patented mold manufacturing process, fine 3D micro-lugs are arranged in a stepped manner on the "lugs" that grip the ground. This increases the force (traction) that grips the ground during walking and propels you forward by up to 25%. EVERBRIGHT®️ EVERBRIGHT® zippers are highly polished metal zippers. They also have superior corrosion resistance compared to standard metal zippers.
