4 pairs of shoes… he has got to be kidding!

I cannot believe that he has put a limit on shoes. How can anyone select only 4 pairs of shoes when travelling for an undefined time? I mean, just off the top of my head, there are:
Winter shoes
• Summer shoes
• Spring shoes (for when we go to the races)
• Work shoes
• Hiking boots
• Joggers
• Pluggers
• Day shoes and
• Evening shoes.
To me, the above is the bare minimum, so how does anyone cut this to only 4 pairs of shoes? I have never heard of such obtuse thinking in my life!
4 pairs… This is going to be interesting. I’m already thinking of where I can hide shoes in the car…
