Cut Outs 0002 Bill Javelin

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.

  • Activity level 3
  • Submersion to a depth of 1m

Javelin Clinical Evidence Reference

Clinical Outcomes using e-carbon feet

  • Safety
    • High mean radius of curvature for Esprit-style e-carbon feet2: “The larger the radius of curvature, the more stable is the foot”
  • Mobility
    • 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
  • Loading symmetry
    • Users demonstrate confidence in prosthetic loading during high activity6
    • Improved prosthetic push-off work compared to SACH feet7
    • Increased prosthetic positive work done4
  • User satisfaction
    • High degree of user satisfaction, particularly with high activity users8

*Component weight shown is for a size 26cm without foot shell.
