So remember: The bare minimum amount of activity to stay healthy and sleep well is 150/75 minutes of moderate/vigorous activity a week; double that amount if your goal is to lose weight.
To prevent corns and calluses and relieve discomfort if they develop: Do not wear shoes that are too tight or too loose. Wear well-padded shoes with open toes or a deep toe box (the part of the shoe that surrounds the toes). If necessary, have a cobbler stretch the shoes in the area where the corn or callus is located.
Treatment of Dry Skin on the Foot. If your feet have calluses, cracked skin, wounds, or rashes, dry skin that does not improve with creams or lotions, an evaluation by a podiatrist is a good place to start -- most importantly to identify and treat secondary causes of dry skin, such as athlete's foot or eczema.
