The term "shear thickening material" is intended to encompass a range of combinations of all shear thickening materials and shear thickening materials known to those skilled in the art. Shear thickening materials or expanding materials. Examples include, but are not limited to, shearing thickening fluids; shearing thickened gelled bodies; encapsulating fluids or gelled bodies; shearing thickened foaming materials; shearing thickened solids; shearing thickened filaments Impregnated fiber (eg absorbed, / or coated with fibers or yarns that shear the thickened material; impregnated fiber-reinforced materials (eg, fabrics that have been absorbed and/or coated with a shear thickened material, wherein the impregnated fiber-reinforced material includes previously woven at The fibers are impregnated together to form a fabric; the sheared thickened composition (for example, a solid foamed synthetic polymer having elasticity, and/or an elastomer matrix and a polymer-based expander different from the solid foamed synthetic polymer) Wherein the polymer-based swell is distributed through the substrate and incorporated therein during manufacture; and a solid, closed-cell foamed material matrix having a polymer-based swell, distributed differently than the substrate; The thickened layer is sheared (e.g., a layer of material from one of the above categories of shear thickened materials, or a combination thereof). Shear thickened or expanded materials have properties that distinguish them from other materials. For example, when the shear thickened material is subjected to an increased ratio of shear deformation, they suffer from an increase in viscosity and/or hardness. For example, when not subjected to shear deformation or subjected to a low ratio of shear deformation, the shear thickened material can exhibit a low viscosity fluid, but can exhibit a high viscosity fluid when subjected to a high ratio of shear deformation. Another shear thickening material can behave like a fluid when subjected to shear deformation or subjected to a low ratio of shear deformation, but when subjected to high

-10- (D 201200051 ratio of shear deformation, can appear like quasi-solid or solid. When not subjected to shear deformation or subjected to low ratio shear deformation, another shear thickening material can appear like quasi-solid Or a flexible solid state, but when subjected to a high ratio of shear deformation, can behave like a hard solid. Shear thickened foamed material can be desirable for use in such areas. To form a bubble in a sheared thickened fluid or gelled body by capture using physical or chemical methods, the material can be cured afterwards. Shear thickening of the shear thickened foamed material After the behavior, the interaction and mechanism can be similar to those of other shear thickened materials. When the shear thickened foamed material is subjected to the energy of a sudden impact, its hardness can be increased. Under normal conditions, the shear thickened foam material can be quite flexible. A suitable shear thickening foam material is a polyurethane foaming material from Rogers Corporation as P ( ) the name of the RON® XRD is marketed, and It is formed to have various densities and properties. Other shear thickened foamed materials can be used in the reaction zones and can be used by other manufacturers. In any of the preceding embodiments, the reaction zones The foot bed may be molded or separately formed in the same manufacturing operation. If desired, the reaction zones may be wrapped or covered with another material' and used such as adhesive, heat seal, etc. Various techniques are inserted into the foot bed. Also, if desired, various additives and/or active agents may be included in the materials, as described in the '26 application. The insole for a particular individual or group of people, the size, shape and configuration of the reaction zones can be varied, such as the material and material properties (eg density, hardness tester, rebound) that form the reaction -11 - 201200051 region The modulus of elasticity, etc. can vary. For example, the reaction areas of the insole can comprise the same or different materials, and they can comprise materials having a graded thickness, a graded density, or both. The configuration of 5 can be customized to respond to the individual's pace by using a combination of materials having different characteristics such as gelatinous, foamed materials, special energy dispersing foaming materials, and others. Material, in combination with such prior materials. In a specific embodiment, an energy dispersive foaming material having such a low rebound characteristic can be used in a region where a relatively low rebound can be a desired foot bed. The reaction zones are formed such that the area formed by a low rebound material can feel soft when touched, but hardens when impacted. Alternatively, it can be desirable to be in the heel cup 20 and/or The periphery of the arched support 30 has a low bounce. When walking, the heel cup and arched support regions 20, 30 will harden when the user's foot hits the ground, thereby stiffening the foot The proper position of the arch is maintained in the insole. Suitable materials for use in such areas are available from the microporous urethane foam material from Rogers under the product name Poron XRD. Poron XRD is available with 'variable buffer, impact resistance, and bounce characteristics. Comparable materials are available from other manufacturers. In another exemplary embodiment, it may be desirable for certain areas having a relatively high bounce. For example, the hips may have a relatively high rebound in the heel pad 4//or the tibial pad 5〇, such that the number of "bounces" is quite low when walking or running. Furthermore, Poron XRD can be a suitable material for this application. 5 201200051 Insole of the present disclosure may be advantageous in comparison to other orthotic shoes because their weight is relatively light, simple to manufacture and inexpensive.
