    • The present invention is directed to an asymmetric shoe which provides greater support, proper flexion and a more accurate fit than conventional shoes. The shoe of the present invention structures one or more of the following portions of the shoe upper and sole asymmetrically between the medial and lateral sides. First, a lateral stability strap is positioned immediately posterior of the fifth metatarsal-phalanges joint while a medial stability strap is positioned posterior of the first metatarsal-phalanges joint. Second, a lateral flex notch is aligned with the fifth metatarsal-phalanges joint and a medial flex notch is aligned with the first metatarsal-phalangess joint to allow the shoe to flex along the foot's natural flex line. Third, a medial quarter notch is positioned anterior of a lateral quarter notch to accommodate the difference between the medial and lateral malleolar lengths. The asymmetry of malleolar heights is also accommodated by having a quarter height difference; the medial quarter height being as much as 2.5 cm. higher than the lateral quarter height. Fourth, the anterior edge of a midsole wedge section is aligned immediately posterior of the metatarsal-phalanges joints. Fifth, in a combination lasted shoe the anterior edge of a board is aligned immediately posterior of the metatarsal-phalanges joint.
    • 本发明涉及一种非对称鞋,其提供比常规鞋更大的支撑,适当的屈曲和更准确的配合。 本发明的鞋在内侧和外侧之间不对称地构造鞋上部和鞋底的以下部分中的一个或多个。 首先,横向稳定带位于第五跖骨 - 趾骨关节的正后方,而内侧稳定带位于第一跖骨 - 趾骨关节后面。 第二,横向弯曲凹口与第五跖骨 - 趾关节对准,并且中间弯曲凹口与第一跖骨 - 无筋关节对准,以允许鞋沿着脚的自然弯曲线弯曲。 第三,中间四分之一凹口位于侧面四分之一切口的前面,以适应内侧和外侧踝部长度之间的差异。 桅杆高度的不对称性也通过具有四分之一高度差来适应; 内侧四分之一高度高达2.5厘米。 高于侧面四分之一高度。 第四,中底楔形部分的前边缘在跖骨 - 趾骨关节的后方对齐。 第五,在组合中,鞋的前边缘在跖骨 - 趾骨关节的后方对齐。
