Aida, since most of my clothes are neutral colors, I tend to just get a few shoes/boots in neutral colors, and then expand to more colorful shoewear. I find that I get soooo much wear out of the colorful shoewear because it just adds a nice pop of color to my outfits - I often coordinate my shoes/boots to my jewelry or scarves. Also, I tend to wear almost exculsively "cool" colors - so I have very few brown shoes/boots - but rather, grays, blacks, blues, teals, purples, burgandy, cherry reds, etc. are all colors that I have in shoe/boot-wear that work for my wardrobe. I do not get hung up at all on having to have both brown, gray, and black in each style, heel heighth, etc. - for example, I have a pair of dark lace-up gray flat-heeled boots that work for either black or gray, so I don't feel a need to buy a black lace-up flat-heeled boot. The gray pair fills in just fine!
