Blister moleskin is a stalwart of the blister management scene. So, it might surprise you when I say I think it's a bit over-rated. Here’s why.
Friction - it has two different meanings. So, the next time you get a friction blister on your foot, this is what you need to know, and do for best results.
Friction is unmistakably part of what causes foot blisters. This is bad friction. However, there is good friction. In fact, it's vital to the way we walk.
It's a popular belief that foot blisters are a type of burn blister. It sounds feasible. Rubbing two sticks together generates enough heat to start a fire!
When it comes to friction blisters on the feet, is rubbing the problem? The solution? Or both? Let me explain the rubbing paradox.
Friction isn’t a bad thing, even if you're getting blisters. Without it, your foot would slide around too much. But you need targeted friction management.
Static friction causes blisters because it results in more shear stress than dynamic friction. Imagining the foot as a wobbly box helps to explain.
The shoe-sock interface holds huge potential for blister care (prevention and treatment). One of the main advantages is the potential for a lasting effect.
Pressure itself doesn’t cause blisters! We need friction to. So why do we call them friction blisters, not a pressure blister?
