I wore Dr. Martens for decades starting in the early 80's. I generally did jobs that involved a lot of standing on concrete floors 8+ hrs a day, and they definitely made a difference. Docs were made in the UK then, and the original model 1460 8-eyelets were unchanged since the 50s.
Then production was moved to China, and they didn't fit the same, and the leather uppers would crack and split before the soles were close to worn out. I still put 'em on to ride motorcycles in town but wouldn't bring them as say, my one pair of shoes for a casual trip.
A couple years ago they re-introduced classic 1460s made in the UK. Just like the old ones - made on the original lasts, same leather, soles, stitching, everything. The downside is they're about $200 and I was gun shy. Recently however I got an email about a 35% off sale from the Dr. Martens online store which got the UK classics down to an acceptable price and I pulled the trigger.
It's like the clock was reset to 1983. Perfect fit, comfortable within a couple days, nice build quality, the leather is breaking in w/o showing creases that will become cracks. Ahhh.
Very highly recommended.
