The sole 1, which consists mainly of impregnation material enters only in a small proportion fits perfectly to the foot, lets it perspire and does not electrically isolate the person wearing it, being therefore healthier than for example rubber soles, but it does not fray like fiber soles without impregnation, so its duration is several times greater than that of these.
