Adjust the distance between the two shells, at the level of the heel, by acting on the lateral tie rods of the heel. Apply the blades to both sides of the ankle in order to cover the malleoli. Apply and tighten the lower strap. Insert the foot wearing the orthosis into a spacious and stable shoe (the shoe must be adjustable with laces or with self-adhesive closure). Adjust the closure of the shoe. Apply the top strap. After a few days of use, the straps may loosen; in this case tighten properly again. If localized disturbance appears, loosen the straps and reposition the shells. The air bearings are already pressurized so that no further adjustments are required, however the tube supplied allows them to be inflated or deflated if necessary.
