  • Patent number: 6432001
    Abstract: A foot position training apparatus for teaching proper foot position for batting a baseball includes a foot support member formed in the shape of the sole of a shoe. A toe portion is attached to a front edge of the support member and extends upwardly and rearwardly therefrom and defines a space for receiving the toes of a batter's foot and, more particularly, for receiving the toe portion of a batter's shoe. The toe portion restricts vertical movement of a batter's foot when batting a baseball. The apparatus further includes an upstanding wall extending along an outer edge of the support surface between the toe portion and a rear edge for restricting outward lateral movement of a batter's foot when batting a baseball. A plurality of cleats are threadably coupled to a lower surface of the foot support member for selectively engaging a ground surface.
