SpryStep^® Max is a dynamic orthosis designed to provide stability and support for individuals with dorsiflexion issues and knee flexion instability. 
Its advanced composite construction ensures durability and patient comfort, making it suitable for those with significant gait abnormalities. Patients with mild to moderate weakness of the lower limb (weakness of the anterior tibial muscle). Those who have a lower activity level only.

SpryStep^® Max is designed to help individuals with foot drop syndrome, a condition that makes it difficult to lift the front part of the foot. 
This dynamic ankle-foot orthosis (AFO) is tailored for patients experiencing excessive dorsiflexion, knee instability, or quadricep weakness. 
This orthosis is engineered to provide stabilization and support during the stance phase of gait, addressing various biomechanical challenges.

Key benefits of the SpryStep® Max include:

• Strategic Stabilization: The midfoot lateral strut is strategically positioned to optimize gait assistance and stabilization.
• Enhanced Comfort: The anterior shell features a 3D shaped pad with a recessed tibia crest relief zone, ensuring comfort.
