I don't think that has anything to do with it. I have a few pink oxford dress shirts in my closet and a polo but that's about it. Most people don't have a lot of stuff to match these shoes. I mean, I know you like highlighter colored everything but a lot of people try to coordinate their apparel and pink just doesn't work with blues or orange or red, etc.
If Nike started a breast cancer awareness line like Polo does with their "pink pony" then it would be awesome and people could piece together stuff to wear but as it is stand alone pink shoes don't work.
These are basically black and white shoes with a splash of pink. Any white/black combo outfit works, which make these easier to match than a lot of blue-based shoes. You wouldn't want crazy colors as part of your outfit with the shoes anyway.
