Javelin

Suitable for submersion (up to 1 metre)
Activity Level (2) 3 (4)

The Javelin prosthetic foot offers the Level 3/4 user good energy response over a range of low to moderate impact sports and activities. Its blade style design is lightweight and ideal for variable cadence walking and allows a good cosmetic finish.

Key Features

  • Small sizes available
  • e-carbon foot with independent springs
  • Dynamic pylon enhances shock absorption
  • Easy to finish cosmetically
  • Sandal Toe Footshell

Foot shell and glide sock included

Javelin 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
