    • There is disclosed an athletic shoe having grooves in a ground engaging surface of a sole formed concentrically about a pivot point in the ball portion and having traction projections in the form of bristles or columns embedded in the bottom of the grooves. Free ends of the traction projections protrude from the ground engaging surface whereby forces on the free ends of the traction projections perpendicular to the grooves, as when a player is accelerating, causes the projections to bend against the side walls of the grooves which thus support the projections against further bending with the free ends of the projections protruding from the outsole to provide traction. Forces on the free ends of the projections tangentially to the grooves, as when a player pivots, cause the projections to bend into or lay down in the grooves and thus offer little or no traction. The ground engaging surface of the sole is formed of a material having a low coefficient of friction so that the sole can move or pivot relatively freely once the projections have bent into the grooves.
    • 公开了一种运动鞋,其具有在球部的枢轴点周围同心地形成的鞋底的地面接合表面中的槽,并且具有嵌入槽的底部中的刷毛或列的形式的牵引突起。 牵引突起的自由端从地面接合表面突出,从而垂直于凹槽的牵引突起的自由端上的力,如当玩家加速时,使得突起抵靠槽的侧壁弯曲,从而支撑 突出物抵抗进一步的弯曲,凸起的自由端从外底突出以提供牵引力。 在与凹槽切向的突起的自由端上的力,如同玩家枢转时,使突起弯曲进入或放置在凹槽中,从而提供很少或没有牵引力。 鞋底的地面接合表面由具有低摩擦系数的材料形成,使得一旦突起已经弯曲到槽中,鞋底可以相对自由地移动或枢转。
