I'm not obsessed with shoes, but if I have to wear them (I prefer being barefoot) then I want a variety.
Off the top of my head, I have..
3 pairs of running shoes
2 pairs of basic gym shoes
6 pairs of boots (I love boots)
Approx. 12 pairs of flip flops (cheap footwear)
7 pairs of dress heels
4 pairs of dress flats
and more casual shoes than I can count in my head
