    • An arch support (24) in the arch support portion (20) of a shoe may be shaped to the individual configuration of a person's foot. It is made from a material whose torsional deflection is greater than its longitudinal and lateral deflections and includes a layer of a thermoplastic material (26) and layers of a fabric (28,30) disposed on opposite sides of, and impregnated with, the thermoplastic material. The fabric contains threads disposed in two coordinate directions defining a warp (longitudinal direction of the shoe) and a weft (lateral direction). A heel of the shoe includes viscoelastic material (52) contiguous to the heel portion of the shoe to absorb kinetic energy. The heel includes a member (54) to convert kinetic energy to potential energy upon contact of the shoe with the ground and to convert potential energy to kinetic energy upon the lifting of the shoe. This member (54) converts potential energy to kinetic energy in the longitudinal direction of the shoe. Another member (40) at the ball portion (18) of the shoe stores and releases energy, e.g. in the longitudinal direction.
    • 鞋的拱形支撑部分(20)中的拱形支撑(24)可以被成形为人的脚的单独构造。 它由扭曲偏差大于其纵向和横向偏转的材料制成,并且包括热塑性材料层(26)和布置在热塑性塑料的相对侧并浸渍在其中的织物层(28,30) 材料。 织物包含沿着两个坐标方向设置的线,所述两个坐标方向限定翘曲(鞋的纵向)和纬纱(横向)。 鞋的鞋跟包括与鞋的跟部相邻的粘弹性材料(52)以吸收动能。 鞋跟包括一个构件(54),用于在鞋与地面接触时将动能转换成势能,并且在提升鞋时将势能转换成动能。 该构件(54)将势能转换成鞋的纵向方向的动能。 鞋的球部分(18)处的另一个构件(40)存储和释放能量,例如, 在纵向上。
