Dr. Scholl's® Moleskin™ Plus Padding
To prevent a blister:
Wear shoes that are comfortable and fit well, and gradually break-in new shoes.
Keep in mind that stiffer shoes are more likely to cause blistering than a more flexible-fit shoe.
Wear socks with your shoes, to reduce friction of your foot rubbing against your shoes.
Athletic socks that absorb moisture work best.
Use a protective bandage on your foot, or insert a protective covering in your shoe, in areas that are likely to rub and cause blisters (often used at the heel).
Attaching moleskin to the inside of your shoe can be helpful.
