Abstract: An appliance for protecting the bottom end of a human lower limb, and in particular the foot, from propagation of the blast wave and the heat generated by an explosive device of the mine type exploding. The invention provides an ammunition type boot whose sole is constituted by an assembly comprising a dispersion boat-shape, an antifire barrier, and support studs. The assembly provides simultaneously an optimum dispersion effect and satisfactory use for walking and running on any type of ground. It also withstands the explosion, and the heat, and it does not create puncturing projectiles because it constitutes a homogeneous assembly.
