Have been wearing Blundstone field D ring type boots for the last 35+ years at work. I work in a Coal Preparation Plant, so constantly walking through coal slurry or magnetite slurry.

In the last couple of years, I have starting using the 997 zip up style Blundstone boot. The zip ups are so much faster to put on & take off, I probably readjust the laces once a month to maintain good ankle support.
