Those look 'great in theory' but 'in real life' maybe not so much.
This concept depends on your approach to clothes.
This is a level of fussiness that I wouldn't want. I wouldn't take the time to decide an upper, much less change the upper out.
That stiff sole would be a deal breaker for me.
Right now, my shoes tend to be workhorses in neutral colors. I used to have more variety and more color in my wardrobe, but I could never manage all that variety.
I'm sure there is someone who dresses brilliantly, who lives in a warmer climate, and wears dresses and sandals all the time, who loves to play with shoe color in the morning, and who can walk in a still heel, and who will appreciated all this choice.
