Well only feminine guys get pedicures, and we have no real reason to maintain them. Guys get turned on by looks MUCH more than girls get turned on by looks.
Women may not care as much about looks on a superficial level sure, but they notice small details, such as not taking care of your feet, or other things you can control. I wouldn't go as far as getting a pedicure, but I do take care of my feet, not because I've ever dated anyone with a foot fetish, but because women notice every detail and it's generally a good rule to be well kept. I manscape for the same reason.
