The KF-303 serves therapists and users who deal with foot drop after stroke, multiple sclerosis, brain injury or cerebral palsy. Syrebo lists toe drag, a weak or numb foot, easy tripping and a dragging or high-stride gait among the problems it addresses. Syrebo adds foot pronation and ankle-foot sprains to that list.
The brace lifts the front of the foot while the user walks and adds support around the ankle and foot. Syrebo presents this support as an added source of stability. Syrebo says it helps the user walk with ease and confidence, improving gait and mobility. A therapist can adjust the quick-adjust dial to raise or lower cable tension, and the user can do the same with one hand.
Setting is part of the workflow. Indoors, the brace is worn alone, with a wrap across the instep. Outdoors, it is worn with a lace-up shoe, and the lower connector attaches to a shoelace. The same brace therefore works for walking indoors and outdoors, and the user does not switch devices between the two.
A segmented design makes the brace easier to put on and take off, which simplifies each fitting. The material is soft and breathable, only 0.38 mm thick, and the whole brace weighs 79 g. Syrebo describes the feel as barely there. A single size adjusts to most adult feet, from EU shoe size 35 to 46, so one item fits many users. The brace suits adult users. Syrebo lists the brace among its home rehabilitation equipment, so it also suits home use.
