As a runner, I understand more than most the importance of taking care of our feet, from heal to toe, ankle to arch. That said, I've only ever had one professional pedicure, as it was part of a spa package I got as a Christmas gift. It include nail trim and file, cuticle work and an AMAZING paraffin treatment.
I mostly clip, clean and trim my toenails, and buff my heel and rough spots. Occasionally I'll smother the whole foot in vasoline or heavy lotion.
