A device for use in snow skiing instruction to communicate to the skier that the correct "legs together" position is not being maintained. The device provides a sensory signal, audible or tactile, to the skier, on movement of the skier's legs away from each other. A first embodiment includes an accordian pleated cylinder or bellows capable of generating a sound when it is compressed or released from a compressed state, a support plate mounted to the cylinder, and a strap connected to the support plate for mounting the entire device to the inside of one leg of the skier. A second embodiment includes an accordian pleated cylinder or bellows having a rod mounted therein for movement towards and into contact with the skier's leg when the bellows is compressed and for movement away from and out of contact with the skier's leg when the bellows is released from a compressed state.
