These are not mum boots, which I take to mean boots that are practical over particularly fashionable. A good shorthand but actually many women of a certain age, mums or not, might decide to go down that path.
They are too high and too smart for that. They look like going out shoes, worn as others have said with a skirt or dress. In my world they would run the risk of looking overdone/overdressed if worn every day, since being more casual - trainers with everything- is more the look du jour.
