My first pair of Red Wing 1155s lasted 19 years. The example on the right is still in service after 13 years. Many miles left but uncertain exactly how many. Rumor is Red Wing may discontinue this boot. Hope not. But to be safe, I picked up another pair. Still reasonably priced; still made in the USA. Bates, Georgia Boot, Rocky, Carolina, and many others I can't remember over the past 30+ years have not come even close to wearing as well as the Red Wings. Worth looking into if you're in the market for new boots.
