Abstract: A high ankle combat boot has multilayered constructions in upper and sole and has a protective function against toxic chemical agents, especially chemical warfare agents. An outer layer in the multilayered upper, away from the foot when the boot is worn, and an inner layer, faces towards the boot. An adsorption layer based on adsorbent material, especially activated carbon spheres, which absorbs toxic chemical agents, especially chemical warfare agents is arranged between the outer layer and the inner layer of the upper. An outsole in the multilayered sole, away from the foot, and an insock, faces towards the foot. An insole based on multilayered aramid cloth, which resists the puncture through the sole when stepping over sharp objects, to prevent infiltration of toxic chemical agents, especially chemical warfare agents, is arranged between the insock and outsole. Efficient protection and a high degree of comfort are achieved.
