I am in industrial maintenance and am constantly walking, climbing, crawling, etc. I am not a young man and also have had foot problems related to diabetes. These have to be the most comfortable shoes I've ever worn - work or not. I don't have foot pain, fatigue or discomfort. They are light and durable. (I'm 60 and my average day is 15,000 steps at work). I actually smile when I put them on.
