Testimonials

"6 days prior to the run(32 miler), I had a hole in my sock which caused a small/medium blister on my heel, this got no worse and I didn’t remember it was there till I took my shoe off. There were no blisters on the arches and nothing new on the heel. Not even a hot spot. They certainly get my thumbs up."

What are Blisters?

How blisters form and the best way to prevent them.

How Blisters Form

A blister is a small pocket of fluid within the upper layers of the skin. It usually forms because the outer layer of the skin has become damaged. Blisters are usually caused by friction or heat. Any rubbing of the skin can cause a blister if it is continued for long enough.

Blisters are the most common sports injury. 40% of marathon runners suffer from them. The pain can severely interrupt the performance of any athlete, whatever the sport, and will spoil the enjoyment of a leisure walker/hiker. Blistered skin can take 5-7 days to recover. Though there are numerous after-care products available, wouldn't it make more sense to try and prevent blisters forming in the first place.

What Contributes to Friction Problems?

  • Poorly fitted footwear (too small, too big, seams in poor locations)
  • Poorly constructed sock (fabric, seams & weave)
  • Debris in footwear
  • Frequent changes in terrain
  • New footwear or insoles
  • Unconditioned feet
  • Foot irregularities (hammer toe, Morton's toe, bony protrusions)
  • Laces too loose or too tight

The list goes on and on …
