My dad has never gotten a pedicure. He is very shy about his feet because when he did weightlifting in college (he is the Massachusetts Institute of Technology 1977 Intermural Weightlifting Champion--a fact which he still brags about today) he dropped a weight on his big toes and his nails have never been quite right since
. Therefore he probably won't let anybody near his feet.
I'm sure that most guys don't do it because they see it as a girl thing. Or they just don't care--if you don't wear open toed shoes or sandals, why bother?
On the other hand, neither my mom nor I have ever had a pedicure. And I don't think I will ever have one--my feet are so sensitive and ticklish that I'd probably kick the poor person working on them.
