An indication device for instructing a predetermined golf swing action, or for instructing a predetermined stance during skiing, includes inserts 1, 6, 10, 22 which are adapted and which can be located in use to provide a tactile indication to the user that a predetermined stance has been maintained or deviated from. In the case of golf, the device is particularly adapted such that when not swinging, no such tactile indication to the golfer is provided. |
