Red Wing Super Sole 8133. The Super Sole construction, patented by Red Wing in the 1970s. By directly setting the one-piece upper, welt, and insole in a mold and injecting urethane foam, it achieved cost reduction, lighter weight, and improved comfort for the boots. The urethane sole, with its excellent cushioning and grip, promises a comfortable fit even for everyday wear. Made with Black Chrome leather. While there is normal wear and tear, it is in good condition with few noticeable scratches or stains. As this is a used item, we would appreciate it if those who understand this would purchase it. ▪️Model number: 8133 ▪️Color: Black ▪️Size: US9.5 D (27.5cm)
