| Summary: | An article of protective footwear in the form of a boot protects a foot of a user against effects of a landmine explosion. A composite sole volume between an outer sole and an inner sole incorporates shock wave guide elements of a material having a high acoustic speed, in the form of glass strips which extend spatially from the outer sole obliquely laterally outwardly to a side of the sole volume. The strips are surrounded by liquid. Above the strips and below the inner sole, there is provided a barrier of material having a low acoustic speed, e.g. vermiculite. Surrounding the foot, opposed to the sole of the foot, there is provided a fluid having a high acoustic speed, e.g. glycerin to ensure effective transfer of any shock wave component entering the foot, away from the foot. |
