My pedicure essentials:
Corn/callus plane (use a new blade every time, and don't use it more than every 6 weeks)
I've used a PedEgg, and hated it. On the balls of my feet, the skin lifts, so the PedEgg just makes it worse. Rasp files just shred my feet.
Pumice stones disintegrate when I use them. My favourite are the cheap plastic foot files with the sandpapery stuff on them.
