Ypsilon® Flow½ is the AFO of choice for your active patients who need sagittal plane assist. Ypsilon® Flow½ has a lower heel height (approx. 7mm) which accommodates gentler contours of shoe insoles and offers more clearance for the forefoot in the shoe toe box. Designed to allow optimum range of motion and dynamic toe-off assist, providing the opportunity for functional or potentially functional muscles, tendons, and ligaments to strengthen and prevent or reduce atrophy.The footplate is engineered to allow the orthosis to adapt to and move with the lower leg with less resistance to ground reaction forces while the proximal ends of the “Y” provide fixation points, eliminating pressure on the tibia crest.Smooth and thin, this interface pad and strap fit close to the leg, ensuring the brace glides smoothly and is barely noticeable under slacks, jean, or trousers. Ypsilon® Flow½ has a heel height that is 7 mm in all sizes.
