BladeXT

Suitable for submersion (up to 1 metre)
Activity Level 4

BladeXT is the complete solution for active users. It is suitable for everyday use as well as running, cycling and other sporting activities, too. It has been designed so that wearers don’t have to stop and change their prostheses between activities throughout the day.

BladeXT is lightweight, flexible and responsive, yet durable. It delivers outstanding performance, ground compliance, comfort and postural support from the twin toe spring and traction heel, while its C-shaped toe spring is primed for optimal energy response. The result is a sports blade that offers the user versatility, security and the confidence to enjoy an active life.

Key Features

  • Ideal for cross training, running, bat and ball sports
  • Controlled acceleration and deceleration
  • Ease of alignment incl. A/P slide
  • Variable spring stiffness heel wedge
  • Heel stiffness adjustment

BladeXT Clinical Evidence Reference

Clinical Outcomes using e-carbon feet

  • High mean radius of curvature for Esprit-style e-carbon feet2: “The larger the radius of curvature, the more stable is the foot”
  • Allow variable running speeds3
  • Increased self-selected walking speed4
  • Elite-style e-carbon feet (L code VL5987) or VT units demonstrate the second highest mobility levels, behind only microprocessor feet5
  • Users demonstrate confidence in prosthetic loading during high activity6
  • Improved prosthetic push-off work compared to SACH feet7
  • Increased prosthetic positive work done4
  • High degree of user satisfaction, particularly with high activity users8
