Some of the most common types of blisters can be prevented.
To prevent blisters caused by rubbing (friction blisters):
Avoid wearing shoes that are too tight or that rub your feet. Roomy footwear has a wide toe box with more room for your toes and the ball of your foot. You should be able to wiggle your toes in your shoes. Foot size may vary half a size from the morning to the evening or after a day at work, so purchase shoes at the end of the day when your feet are most swollen.
Wear gloves to protect your hands when you are doing heavy chores or yard work.
