I haven't used them for work yet. But I will comment on the size. The boots are not true to size. They run a little larger or bigger. The positive part is if you have wide feet. They provide plenty of room in the toe box area. They are lightweight. I work at a hospital and prison. I'm on my feet all day. With that a extra space I can slide in an anti-fatigue sole of some sort for comfort. I gave it 4 stars for comfort and 5 stars for lightweight, and 0 stars for water resistance (I haven't used them yet). Once I put them to the test I'll provide a full review and analysis for you guys!
