I bought my girlfriend some Altama "Urban Assault" shoes for her job a while ago. She is on her feet all day. They still are in excellent shape and the build quality seems very high.

They're more of a skateboard shoe style. But they're made by a company that makes army boots and swat team shoes and stuff.

They are zero drop shoes bc they're designed for "maximum stability" apparently. For police and stuff. And after looking into zero drop shoes and trying to see what the deal is, I will say there are some arguments to be made that zero drop, flat shoes actually being healthier and better for some people, in comparison to shoes with cushioned heels and bigger arch supports.

She has lupus and has joint issues sometimes, and her knees reportedly hurt less once she wore these for a while. Not a big difference, but it was something, switching from a more traditional soled shoe.
