The most practical shoes to wear when juggling baby / toddler, bag, keys etc and running out the door are slip-on, either flip-flops for summer or biker style boots for colder weather. I have them in a vintage hall stand with mirror, so just slip them on and out we go. My brown Havaianas flipflops have lasted me 5 years so far, and I bought them at full price in Office, for I think 30 euros. They look great with a tan, go with everything and are the most comfortable flip-flop around. I found a red pair in TK MAXX this summer, for only 12-13 euro, so now alternate between the two. I can walk all day in these and never feel a thing.
I usually decide a look based on the weather and the shoes I want to wear, and the above four shoes form a perfect capsule wardrobe, covering every occasion.
