I have them too. I opted for the black ones as the rose (although very pretty) clashed with my orange bike.
Another argument for these is what the bike shop guy told my husband and I. "Go with good cycling shoes they last longer and you have less chance of suffering from some foot problem." Not sure if this is true but hey sounds like a good argument when buying expensive cycling shoes.
The most effective way to do it, is to do it.
