How many pairs of shoes do you need?

I have been using only 3 pairs of shoes for the past 2 years. Extreme minimalism or based on logic?
I am a minimalist but I came to the decision of 3 pairs logically. After answering a few of the following questions.
I first answered the question about how many pairs do I actually need. I evaluated my usage and around 2020 I realized that 3 pairs were all I needed.
Next, I answered the question about fashion. If I only have 3 pairs how do I match them based on my outfit or the event? This was the simplest to answer. I didn’t care much about fashion but I made sure all 3 had multiple use cases instead of just once and selecting the correct colors also helped.
The final question was about getting new shoes. What if I want to get new shoes? I decided that I would only get new shoes to replace and not add to the three pairs.
Ever since I decided on these answers I have been happy with my system. I do plan on adding a 4th pair for camping and hiking but that is still not a need yet.

How many pairs do you rely on?
