A good way to get rid of calluses is to soak your feet in a tub of warm water and Epsom salt.
Take a basin or any other tub you have around and put some warm water in the container or tub and pour some Epsom salt into the water and soak your feet in the Epsom salt for at least 10 minutes.
The Epsom salt foot soak will soften the dead skin cells making the calluses easier to remove.
You can then use a pumice stone or callus file to remove the calluses from your feet.
Listerine Vinegar and warm water will also get rid of calluses if you don't have any Epsom salt.
Then you should be able to just wipe the dead skin "calluses" off your feet.
