  • Patent number: 3951407
    Abstract: A device for positioning the shoe of a golfer with the outside edge of the shoe elevated with respect to the inside edge includes a crosspiece extending laterally across the instep of the shoe and a strap which is connected between the opposite ends of the crosspiece to hold the latter on the shoe. An arm is connected pivotally to the inner end portion of the crosspiece to swing between an out-of-the-way position within the instep for walking and a support position for elevating the outside edge of the shoe. In the support position, the outer end portion of the arm is spaced downwardly from the crosspiece to engage the ground and the arm is held in such position by a brace having one end hinged to the outer end portion of the arm and an opposite free end which abuts the crosspiece. To collapse the device for walking, the free end of the brace is swung from beneath the crosspiece to enable the arm to be swung into its out-of-the-way position.
