I think that if you are able to afford a large amount then it's definitely a good thing to have more than just a few. I have about 10 pairs. Although I don't always wear every pair that I own, it is necessary that I keep each one. I think it's necessary for everyone to have at least one or two pairs of walking shoes, a pair of nicer shoes for any special events, sandals (or slides / flip flops) for hotter weather, and possibly a pair of boots if they live somewhere that gets snow or muddy. It's nice to have more though, for options. I wouldn't want to have too many shoes though, as I know some would just sit and never be worn.. but I definitely wouldn't want only a couple pairs either.
