  • Angles of forefoot flexion

    We are in the process of improving our current mechanical tests for measuring
    the forefoot flexibility of footwear (i.e., a torque versus angular
    displacement curve). We want to apply the appropriate boundary conditions
    relative to the sport-category of the shoe.

    I am looking for kinematic information related to the flexing of the forefoot
    during various sporting activities. For instance, if the forefoot (toes) and
    midfoot were assumed to be rigid bodies connected by a single hinge joint
    (i.e., an "average" MP joint) what would be the angle of flexion as a function
    of time. Again, I am interested in this for any and all sport activities.

    Any comments or information would be appreciated.
