Blister 101

Sore blisters on the back of the heels

Blistering on the feet is a common problem for many people who walk, run or play sports. It can be very frustrating and painful if it continues to occur. 

Common thoughts are that blisters are caused by sweating,  moisture, friction, heat or rubbing against the shoe. These are all partially correct however the main cause of blisters is SHEAR.

Shear forces make the skin stretch too much over a bone or joint, beyond the elastic capacity of the skin. A series of small tears occurs under the skin surface and fluid fills up the injured area. The injury, fluid, and pressure all make it feel pretty darn sore!

Why do blisters form?

1. Type of skin
Some people unfortunately are more prone than others to blisters.
2. High amount of friction
With walking and running the foot undergoes large amounts of force. Add wearing shoes to the mix and we have the essential ingredients to form blisters. Friction occurs when the skin, sock and shoe all grip together, causing the skin to stretch and blisters to occur.
3. Moving bone
With every step the bones in your feet move forward relative to the stationary skin. The more the bones move, the more it allows the skin to excessively shear, causing blisters.
4. Repetition
With repeated irritation on a particular area, the skin structures become weakened and blisters form. This is where a culprit shoe (either too big or too small) or bony bump on your foot can come into play, causing blisters to form more easily in certain locations.

Our Podiatrist’s best tips for preventing blisters

  • Have a Podiatrist regularly file away any hard skin near the blister
  • Get your shoes fitted properly by a trusted shoe retailer or Podiatrist
  • Get onto hot spots fast before they become fully formed blisters!
  • Don’t pop the blister! If you’re unsure get a Podiatrist to help
  • Buy  and wear socks with ample padding especially at the heel, forefoot and toes
  • Using sports tape, strap blister prone areas during sport
  • Use products such as Steigen socks and Engo Patches to stop blisters occuring
  • Don’t pop it unless the pressure is causing pain! Get your Podiatrist to help you out
