Blisters are small sacks of fluid between the upper layers of skin. Commonly caused by the rubbing of ill-fitting shoes on the feet, blisters may also be caused by other forms of friction, burns, infection, chemical exposure or freezing. Blisters are usually filled with a clear fluid, though if infected, they may fill with pus.
Duct Tape to Prevent Blisters
- Apply a piece of duct tape to the heel or other part of the foot prone to blisters. The best kind to use is the soft duct tape, which does not have the strapping threads. This may be done once a “hot spot,” or an irritated patch of skin, is felt or as a preventative on spots known to blister. Duct tape must be applied daily.
Why It Works
Duct tape shields the foot from the friction caused by the shoe, thereby eliminating the opportunity for blisters to develop.
Do NOT place duct tape on a blister that has already developed, as it will be extremely painful and prone to infection upon removal. In rare cases, an allergic reaction may occur with the adhesive - stop use if this occurs.
