Elite Blade

PDAC Approved
Suitable for submersion (up to 1 metre)
Activity Level 3 4

A lightweight, high energy return prosthetic foot, the elite blade is ideal for Level 3-4, high impact use from the casual jogger to the serious runner. The flexible extended pylon reduces shock load transmission making it a great crossover foot for work, leisure and sports activities.

Key Features

  • e-carbon foot with independent springs
  • Lightweight with dynamic forward progression
  • Spring range from low to high impact
  • Variable spring stiffness heel wedge
  • Male or female sliding & rotating housings
  • Sandal Toe foot shell

Elite Blade 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
