I can thoroughly recommend getting a white sneaker boot. I have the ones below and have loved wearing them this winter, my best footwear purchase of the year. I am precious about them, and don't wear them when out in heavy rain and sprayed them with protector. But on days when I am predominantly inside or it is not raining they are wonderful.
The white ones you have selected have a dark sole, so I think that will give you a book-end effect. I wear mine with dresses and most items. They feel a bit more dressed up than a true sneaker with the same level of comfort.
