Myth: You deal with foot problems when they show up.
Fact: By then, it's treatment. Engineering works upstream – stop the friction, manage the moisture, hold the fit, so it never starts. Prevention isn't the soft option. It's the harder thing to build.
Waiting until a blister or hot spot appears means you're already in treatment mode. Engineering works one step earlier. Because repeated shear force is what separates the skin's outer layer from the tissue beneath, and moisture raises the friction that drives it, the fix is to intervene before either peaks: cut the friction, manage the moisture, hold the fit.
Building a sock that stops the problem from starting is harder than making one that copes after the fact. Prevention isn't soft. It's the tougher engineering challenge — and it's the one worth solving.
