Abstract: Protective footgear consisting of a multilayered material shaped into an overshoe that protects the foot and lower leg of the wearer from injury due to exploding land mines. In a preferred embodiment of the invention, the overshoe includes a heat-resistant layer, a water-impermeable layer, and a puncture-resistant layer. It may be formed into an overshoe of conventional appearance, or assembled by cutting and folding a suitable multilayered sheet material into a box-like structure that is worn over the user's regular shoe or boot. The multilayered structure consists of materials that, in combination, substantially dissipate the shock of an exploding land mine and thereby reduce the risk of injury to the wearer. The invention is easy to manufacture of readily-available materials, light-weight, reasonably comfortable to wear while walking, reusable and repairable, and provides remarkably effective protection against blast and shrapnel injuries caused by exploding land mines.

Abstract: The invention provides a shoe having a built-in wear-indicator device capable of signalling (a) extent of shoe wear, (b) biomechanical compatibility with the user, (c) loss of the ability to cushion and absorb shock, and (d) a need for shoe replacement. The built-in wear-indicator device is positioned within the midsole and/or outsole and must be made of a material that is less compactible than the surrounding bulk midsole material that functions conventionally to cushion and absorb shock. With prolonged wear the midsole material loses its ability to absorb shock and compacts in the vertical dimension. In contrast, the wear-indicator device, being less compactible than the midsole, continues to protrude into the outsole in response to downward forces exerted on the indicator device. The degree of extension of the wear-indicator device into the outsole is an indicator of loss of ability to cushion and absorb shock and, consequently, of a need for shoe replacement.
