I have several pairs from their "rugged" collection. I believe those are for casual wear more than work wear. My recent job (machinist) requires a steel toe shoes with anti-slip sole (oil and coolant stink), my first thought was a pair of doc. Now, it may be a difficult choice because there are many different styles in their "industrial" line up. I went with this 2216 and could not be happier. I got my shoes next day, amazing! (was only using free 2-days shipping for prime membership).
At my first glance, this shoes do not look bulky at all which I like. I do not want to look like a construction worker and I do not wear loose pants (if ya know what I mean). The sole is far more comfortable than my "rugged" doc. The leather look super heavy duty as well. I am amazed by the overall quality. I did not know this shoes is also ESD safe, which help if you work with sensitive electronic equipment.
No doubt this shoes will last a long time. My regular daily wear doc is 5 years old and looks like it cant go for another 5 w/o a problem. This is far more rugged than mine.
Hope this helps
