Would you buy more than a pair of exactly the same shoes?

No, that would be a waste of money, unless you're buying another pair for someone else.

If I absolutely adored them, yeah. Or if I felt I just needed another pair lol

I have done so.

I bought two pairs of the boots I wear when riding my motorcycle. When one wears out I'll already have another pair to wear.

Absolutely. Especially since I wear Womens Boots and Shoes. They come in a variety of colors. I've bought the same style in different colors. And some of my Boots look exactly the same but one is a short Bootie and the other a Knee Boot.

Not at the same time. I often replace an old pair with a new pair of the same.
