The most important updates:
- The spiral has been reinforced to increase foot support
 - Strengthened anterior plantar for better toe support
 - Superior comfort due to the softened joint between the spiral and the sole
 - Functional calf grip: right mix of flexibility (to permit flexible adjustment to different calf circumferences) and stiffness (to avoid twisting during use)
 - Thinner calf pads to improve the profile and fit the brace better
