The invention relates to body supports and teaching aids particular for use during skiing. Skiing to greater or to lesser degrees imposes strains on the muscles of the skier causing fatigue and encouraging a skier to adopt an incorrect stance or posture not conducive to good and correct skiing. The object of the invention is to provide a simple and effective body support and teaching aid that is effective during skiing and does not need to be removed during a temporary cessation of activity but allows substantial freedom of movement of the legs during walking and sitting. This objective is met by a construction comprising a first (upper) member adapted for location against the thigh area of the leg, a second (lower) member adapted for location against the calf area of the leg, a pivotal connection between the first and second members, the second member being connectable to the boot of a user, load bearing means located on the support to provide a resistance to pivotal movement between the first and second members, and said load bearing means being deactivatable to permit substantially free pivotal movement between the first and second members.
