I discovered these blister block bandages several years ago. Now, I always pack some in my suitcase when travelling.
They really do work to heal blisters, and they provide a cushioning pad during the healing process, which facilitates your ability to keep on your feet and on the move while travelling, and at the same time, reducing the risk of infection.
Obviously, people who have a propensity to suffer foot blisters should seek prudent medical advice.
However, for the casual traveller who develops foot blisters after long walks, these can be very helpful!
