RED WING Red Wing Product Number: 8173 Size: US7.5E (25.5cm) Condition: 8.5 out of 10 The right sole is slightly worn, but overall, I think it's in good condition. The 8173 was born in 1989 as a Japan-exclusive model, using Hawthorne Abilene, a beige roughout leather that was mainly used for Western-style boots like Pecos boots and outdoor boots in the American market at the time, based on the 875. Unlike many suede leathers, which are made by thinly slicing the brushed surface of the leather, roughout leather uses the grain side (the surface of the leather), which has the highest fiber density, on the inside and the brushed surface on the outside. In other words, it's made by turning the leather inside out, and it was originally often used for outdoor shoes. The 8173, which combines the 875's design with this roughout leather, has been loved in the Japanese market since its release and continues to be a long-selling product to this day.
