Abstract:
     An article of protective footwear in the form of a boot ( 10 ) protects a foot ( 12 ) of a user against effects of a landmine explosion. A composite sole volume ( 16 ) between an outer sole ( 18 ) and an inner sole ( 20 ) incorporates shock wave guide elements ( 28 ) of a material having a high acoustic speed, in the form of glass strips which extend spatially from the outer sole ( 18 ) obliquely laterally outwardly to a side of the sole volume. The strips ( 28 ) are surrounded by liquid. Above the strips ( 28 ) and below the inner sole ( 20 ), there is provided a barrier of material having a low acoustic speed, e.g. vermiculite. Surrounding the foot ( 12 ), 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.
