I'm god damn shoe obsessed and I don't have that many. I got:
-Sports shoes
-Work shoes (thick, leather, sturdy)
-Fancy boots (black)
-Fancy boots (white)
The only boots I ever got purely to match was the two pairs of black and white fancy boots. Which is more than enough to be complimentary to any wardrobe depending on if I use brighter or darker colors. What more could you need? Two pairs of sports shoes? Two pairs of work shoes if you wanna be extra? But even that only brings you up to 6 and I can't fathom needing more.
Like I consider myself a shoe obsessed woman. I pride myself in my silly little stompers yet I can't imagine owning more then 6 at a time. Unless you count during my lifetime because yeah boots got replaced as old ones wore out. I needed to replace the white ones as they literally fell apart, went through several rounds of work and sports shoes too.
And without getting into the varieties of hiking/trail running/etc. You can easily encounter situations in that genre alone that necessitate 2 or more. Waterproof or not, trail running vs hiking vs thruhiking, the list goes on and on.
Editting to add: this isn't unique to hiking either, you'd find similar variations in runners too. Endurance, sprint, or agility (among others) running are all different enough you'd have genuine performance and health reasons to separate the shoes. Obviously hardly anyone will dedicate to that many unique activities, but some people really enjoy them so it's worth explaining.
I've seen men and women have boxes of shoes filling their small closet. It's a weird thing to see and then explaining is no different. Everybody has their drug, if you know what I mean.
I used to be way more consumer-y and I've been slowly reforming my ways. Case in point, two of those pairs are old running shoes repurposed into general beaters, and 10 of them were purchased 5+ years ago.
I have sizes 47 and 48 pairs of shoes. Not used as it was very large for my feet, which is technically 44-45 when I received shoes that belonged to my late American uncle in September.
