Fill a large bowl with warm water and soak your feet for 10 minutes. This will help to soften the callus and make it easier to remove.
Leave your feet in the water and begin rubbing the callused area with a pumice stone. Use a smooth, back-and-forth motion, pressing gently on the stone as you rub away layers of hardened skin.
Remove your feet from the water and towel them off.
Massage moisturizer into your freshly scrubbed feet. Soothe those callused areas with a generous amount of skin-softening lotion.
Place a callus bandage over the callus. This will protect it from pressure and stop it from getting larger. Find these bandages in the foot-care aisle of your drugstore.
Pull on a pair of cushioned socks. This will keep your feet cozy and prevent friction while they're inside your shoes.
Insert padded insoles into your shoes. These also are available in the foot-care aisle and come in a wide variety of sizes and shapes. They cushion your feet and reduce pressure while you deal with calluses.
Large calluses may require several days of treatment to be completely removed. Soak, pumice, moisturize and protect your feet every day until the callus disappears.
