Ah, I don't see why a person can't buy 3 pairs of the same shoes, in different colors, if they want to and have the money... I mean, unless they are spending their kid's food money, why should anyone care?
I wear a size 5.5 or 6. I can't just go and buy a pair of shoes when i need something specific. It takes a trip or two to DSW and perusing the Internet. While, I have never bought more than one of the same style, I often buy 2 or 3 pairs in one shopping trip, because I know the next time, the ones I like and fit me will be gone.
I don't think we should put people down or say they should give the money to charity. How we spend our money is a personal decision. How many of us actually need a bike that costs $2,000-$6,000?

And, red shoes are very cool!
