The Blister Blog
After enduring a scorching bitumen surface for 135km, I had developed 2 x 20c coin-sized blisters under the forefoot of my right foot.
Running around a 1.1km track proved an excellent format as my first ultramarathon. It allowed the preventative / early intervention approach I'm interested in.
Sure, prevention work some of the time. But when it doesn't, we're at a loss to explain why. Is rubbing the problem? Is it the solution? Or is it both?
There's one thing you should know about blister prevention (if you don't already). And that's "What worked for you today, may not work tomorrow".
An edge blister is a blister that’s kind of on the bottom of the foot, but it’s a bit on the side too. Watch this video for the full story.
“... many myths continue to be propagated regarding the prevention and treatment of friction blisters” Douglas Richie DPM (2010).
ENGO Patches can’t fix every pain in the foot. There are limitations you should be aware of. Like they can't relieve pressure - ENGO Patches minimise friction.
Peter contacted me with questions about preventing foot blisters in his 2nd Melbourne Oxfam Trailwalker. His experience serves as a reminder to Trailwalkers.
Shoe fit is your first and most important blister prevention consideration. This revolves around length, width and adjustability. Here's how to get it right.
Friction plays a big part in making blisters. But friction isn’t a bad thing. You need friction for traction. Without it, your foot would slide around too much.
Blister incidence has been investigated in athletes, hikers and military populations and ranges from 33% - 50%.
Static friction causes blisters because it results in more shear than dynamic friction. Imagining the foot as a wobbly box helps to explain.
The shoe-sock interface holds huge potential for blister prevention. One of the main advantages is the potential for a truly long-lasting effect.
Pressure doesn’t cause blisters! But it is part of the problem. Why do we call them friction blisters, not pressure blisters? Let me show you why.
