The ultralight NEURO CLASSIC Carbon System Ankle Joint is suitable for the production of a water-resistant AFO to guide and stabilise the ankle joint. The system stirrup used has no dorsiflexion or plantar flexion stop. Therefore, the system joint is free moving as well. Thanks to its robust, carbon fibre-reinforced joint case, it is dirt- and water-resistant. The NEURO CLASSIC Carbon system ankle joint can be used as a supporting joint for the NEURO SWING Carbon system ankle joint.
