Abstract
Protective boot (see fig. 1) is made up of an upper (1) with a tension insole and an attached system of bottom boot segment based on at least two middle soles and a sole. At least one layer of para-aramid fiber based reinforcing textile (2) is inserted and/or cemented between the top material (1) and the lining. The tension insole and/or at least one of the middle soles (5, 8) are based on composites of at least three layers of para-aramid fiber textile fixed in a polymer matrix and the whole bottom segment of the boot is formed by a sandwich design. The density of the individual material parts in this sandwich system of middle soles (5, 8) and the sole (9) in the bottom segment of the boot differs in a way that the difference in the density of the various composite materials used in the adjacent middle soles (5, 8), or to be more precise the sole (9), and the difference in the density of the adjacent layers in the sandwich multilayer structure of the corresponding middle sole (5, 8) must be at least 0.1 g/cm3 and the material hardness in the individual parts of the system of middle soles (5, 8) and the sole (9) in the bottom segment of the boot differ in a way that difference in the hardness of the composite materials in the adjacent middle soles (5, 8), or to be more precise sole (9), and the difference in the hardness of the adjacent layers of the sandwich multilayer structure of the corresponding middle sole (5, 8) must be at least 1 ShA. Thickness of each individual middle sole (5, 8) and the sole (9) of the sandwich system must be at least 10 mm and the total thickness of the middle soles and sole system in the bottom segment of the boot must be at least 30 mm.

Statement under article 19(1)
While the previous designs of the blast protective boots according to WO 03/037125 Al (document Dl in the report on the international background research) was founded mainly on the plating system of the ballistic reinforcement material and placement of the individual layers of ballistic material with mutual rotation, the new design according to PCT/CZ2010/000038 has to do with the optimum combination of individual layers in the sandwich structure of the insole, middle sole system and the bottom boot segment sole. The essence of the optimum combination lies in the difference of density and hardness in the adjacent layers of the sandwich structure's insole, respective middle sole, or more precisely sole.
The primary pressure wave caused by mine explosion is being broken up and deflected upon its passing between two layers of various densities and hardness. This therefore causes secondary counter waves, which are reacting against the initial wave. At the same time the layered sandwich material is being separated by gradual peeling of the individual layers and it thereby absorbs the first pressure wave's energy. Ballistic material in the sandwich dampens the primary wave and at the same time it serves as perforation protection, i.e. prevents shrapnel penetration.
It is being proven in practice that the focus on the abovementioned optimum composition of the middle sole layers and sole in the blast protective boots brought a significant improvement in the boot's protective properties whereas this innovative design lead to the successful completion of testing and the acquisition of an EN certificate for boots with effective protection against landmines. To prove this fact we attach the respective certificate issued by the official testing laboratory.
