Previous investigations about the running shoe design demonstrated a relationship between the geometry of the shoe sole, the ground reaction forces and the foot movements during impact. Thus, the question arised in which way this relationship would influence the internal forces. The purpose of this investigation was to model the impact situation and to simulate different sole geometries in order to calculate the internal forces and the pronation velocity. The results show that the geometry has a small effect upon the joint forces, but a very high effect on the pronation velocity. As a consequence, the joint forces changed only by 10% or less, but the load of the structures which are stressed by pronation is increased up to 200%. Thus, the control of the initial pronation is much more important in current running shoe design than the shock-absorption.
先前关于跑鞋设计的研究表明，鞋底几何形状、地面反作用力与着地时的脚部运动之间存在关联。因此，出现了这样一个问题：这种关系会以何种方式影响内力。本研究的目的是对着地情况进行建模，并模拟不同的鞋底几何形状，以便计算内力和内旋速度。结果表明，几何形状对关节力的影响较小，但对内旋速度的影响非常大。因此，关节力仅改变了10%或更少，但因内旋而受力的结构负荷增加了高达200%。因此，在当前的跑鞋设计中，控制初始内旋比减震更为重要。
