The way I get rid of corns on my toes is to soak my toes in some warm water.
When soaking your toes in the warm water make sure your corns are submerged in the water fully and allow your corns on your toes to soak in the warm water for at least 10 minutes or until the skin softens up.
After you've softened the skin of the corns on your toes in the water take a pumice stone and file away the corns on your toes.
You want the skin soften so the corns come off of the toes easily.
A pumice stone works great for filing away dead skin as well but you want the skin to be soften by soaking it in warm water first.
Then the pumice stone should easily shave off the corns on your toes.
After removing the corns on your toes you should also apply some moisturizing lotion.
