    • The effective friction of a shoe is adjusted by changing the angle of a portion of the sole, relative to the shoe centerline. In one embodiment, the heel is effectively hinged and an adjustment device is spaced from the hinge axis, whereby the wearer can hold the shoe in one hand and manually adjust an actuator connected to a drive member that increases or decreases the angle of the hinge. The hinge axis can be perpendicular to the centerline, either in the front of the heel with the drive member embedded in the back of the heel, or in the back of the heel, with the drive member embedded in the front of the heel. Angulation can be effected in the foresole, about an axis perpendicular to the shoe centerline, or about an axis that is parallel to but offset from the centerline.
    • 通过改变鞋底的一部分相对于鞋中心线的角度来调节鞋的有效摩擦。 在一个实施例中,脚跟有效地铰接并且调节装置与铰链轴线间隔开,由此穿用者可以用一只手握住鞋并手动调节连接至驱动构件的致动器,该致动器增加或减小铰链的角度。 铰链轴可以垂直于中心线,或者在跟部的前部中,驱动构件嵌入脚跟的后部中,或者在跟部的后部中,驱动构件嵌入脚跟的前部中。 可以在鞋外底,关于垂直于鞋中心线的轴线或关于与中心线平行但偏离中心线的轴线实现角度。
