I wear Nurse Mates Dove
shoes, and love them. They are flat and simple, no fancy, wobbly heels. Even though they are very simple, I have found they have a good sole design that offers enough support for a 12 hour shift. I used to work on a tele floor and I often ran for the entire 12 hours solid, and usually my feet would be tired but not painful. I have to get a wide in them even though I don't wear wide in any other brand. I also pair them with compression socks and that makes a huge difference. Also, the Doves are not super expensive. Maybe RNs can afford $160 shoes, but this lowly aide cannot! :-)
Word of warning.... the patent ones crack REALLY easily, which is why they are so cheap on Amazon
. If you don't care and want to save a ton of money, go ahead and get them. But I think the plain flat black ones are the best.
