sorting shoes

How does one minimalist-leaning woman manage to amass so many pairs of shoes?
And how many is too many?
Here's what I have currently. When I put them all together, it was more than I expected.

I think it's too many. But I do wear almost all of them often. The ones I don't wear as often are the fancier sandals that would cost a lot to replace for the few occasions I would want them.

Brown Keen boots-fall/winter/spring
Black Dansko clogs-daily work (beloved by nurses and teachers everywhere, so comfortable)
Brown Keens-summer sandals and walking shoes
Brown Italian leather sandals-had for 18 years! Rarely wear, but still nice.
Black flat sandals-black summer shoes
Slippers-home, cold tile floors in the winter
Blue plastic clogs-gardening and chicken tending
Nike running shoes-handmedown from P'tit Minou 1, worn out
Trail running shoes-see above

Yikes! One place I think I could trim down is by sticking to either brown or black and not having two sets of colors. I actually tried this--choosing black because it seemed the more basic--but truth be told, I missed brown (I had hung onto the shoes to see how it went). I'm an earth-tone kind of gal. I also have two nice brown skirts that were given to me that I'm reluctant to part with, so I figured I will hold on to them until...?

So how can I trim? This is too much shoe volume in a small home. Also, I preach minimalism at home, but I have more pairs of shoes than anyone else in my household. Ahem. Though my feet have stopped growing, unlike some!

Here are P'tit Minou Deux's pairs:

 He loves the black leather ones (which are falling apart). Summer sandal season will soon be over.
The two pairs of running shoes above were inherited from P'tit Minou 1 (who was the other runner in the family until being sidelined by a knee injury--don't let your early teens run half-marathons, even if they want to!). P'tit Minou 2 is not a fan of running shoes and never wants to wear those.

So I think that I will get rid of my two worn-through pairs of running shoes (after today's long run: 10 miles!) and instead adopt G2's darker pair. Which leaves each of us with one less pair of shoes. His leather ones will need to be replaced soon, but we will throw away the older one.

As I write all this I can't help thinking about what a first-world problem I am having. My friend S., when leaving her Peace Corps stint in Guatemala, collected money from friends at home because she wanted to leave each woman and child she had worked with on a garden project with at least one pair of shoes. One.

This is my life now. Aiming to simplify and finding it a struggle, while others in the world struggle to meet basic needs.
It's not right or fair.

I still have more shoes than anyone else in the family, though. Ideas? I want to trim down!
