I have been a long time customer of Dr Martens work boots. For me they last twice as long as any other work boot that I have tried. I prefer these as they reduce my lower back pain as well. Unfortunately, this work boot comes with D30 drop protection in the toe. This has made the break-in period unbearable. I have had to relace the boot to stop the pressure on the top of my foot. Personally I think they have wrecked the best work boot that was on the market.
