Abstract: A portable golfing aid conditions the golfer to swing on a constant arc by limiting and restraining the pivot foot from lifting or pivoting. Base members which are spaced a shoe width apart are removably secured with respect to the ground or mounted on a pad or mat. Slotted portions of the base members receive a removable adjustable strap which connects the base members and bridges the front instep portion of the golfer's shoe and may be angled snugly across the instep. The golfing aid may be equipped with foldable ground engaging legs and when folded collapses to fit in a pocket in a golf bag. A less portable mat-mounted device is provided with pivoting adjustability for an angulated foot position.
