This is a vintage trekking boot, the ZOOM AIR TRICO (Zoom Air Trico), released in the 1990s by NIKE ACG (Nike All Conditions Gear). Color: Brown Size: 23cm These are substantial-feeling shoes. The thick leather patterning is excellent, and the plastic parts around the ankle are also a distinctive feature. Unused items from this era are rarely found. They have been stored without being used, so they are unused, but there are some stains (on the left side). Please check the images for the condition. No claims, no returns. Please refrain from purchasing if you are sensitive about condition.
