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.
Corns and calluses can be long-term problems if you consistently wear shoes that do not fit properly. Even with good footwear, you may continue to have painful corns and calluses if there is some abnormality in your gait or foot structure that causes unusual stress on parts of your feet when you walk.
