100% OF CHICKS DIG IT
To prevent rubbing the foot to the shoe or boot before blisters form, this is a good way to ads cushioning while preventing it from moving as much. The adhesive lasts several hours and generally stays in place. It is pricey and usually comes as one sheet. To save time, cutting them up into smaller pieces can help before a hike or walk.
Not useful once the blister form though - it may end up adding more pressure to that area and cause it to burst.
