I am entering nursing school in the fall for my ADN program. I have everything I need, but will still need to buy shoes to wear to clinical. The only guidelines for my school are that they must be white or black professional shoes. Open back clogs and canvas shoes are not allowed. I would prefer black, just because I know how fast white gets dirty and gross! Any recommendations on brands and styles that will be most comfortable? I do like stylish, but comfort goes above anything else in my book!
