A nice shade of color enhances the powerful magic of female feet but I have to tell you that I also like her feet in that raw and primal state. (if you know what I mean)
It gives variety and contrast to the whole color show.
Clean nails turn me on...
I therefore see the clear gloss as a kind of showcase to accent the natural primal beauty of her feet.
Besides that, with nail color theres no telling whether or not she has really clean nails. I mean there could be mounds of dirt underneath those nails
and you would never know that if she was wearing nothing but color all the time.
Smelly feet (such as the fresh aroma of her feet encased in nylons for the whole day or after a gym workout/run) are just fine with me and a major turn on
but dirty nails and/or feet are a major turnoff. (at least thats how it is for me)
Anyway thats my 2 cents on this topic.
