Key Features
Carbon composite elementsStore energy under load and release it during push-off, delivering a smoother, more elastic, and better-controlled step.
Wave springCreates a soft heel and effectively absorbs impact at initial contact, promoting early postural stability and reducing undesirable shock loads.
Primary spring (elastic sole plate)Supports a natural heel-to-toe roll-over, enhances confidence when walking on uneven surfaces, and provides dynamic push-off.
