I have 4 pairs of shoes I rotate through. I have my Nike Air Monarchs, Nike ACG Boots, Reeboks...I don't know what...they're all black...haha...and some Adidas Sambas. Only one of these fits their current qualifications of uniform work shoes. Which is kind of amusing to me...When I was hired, they said to think of myself as an athlete and to treat my feet like an athlete would. I've checked the feet of many an athlete and only soldiers wear boots. And that's in intake training and combat maneuvers. Other than that...cross trainers. I know my feet and ankles better than any safety committee or managerial safety person. I have injured my ankles and broken the tarsal bones on my feet more with boots than the cross trainers. In 18 years, I've tried Danner's (really good boots...still broke a tarsal bone and twisted my ankle in those)Red Wings (ankles), White's (an expensive lesson) and now the Nike ACG boots (so far so good). Time's I've injured myself in the cross trainers? None. Oddly enough when my ankle is allowed to bend a little I have a chance to correct myself and collapse before sprains occur. In boots my ankle is stuck in one position and sprains almost immediately. Just my experience.
