Esprit

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

The Esprit foot is a low profile foot for moderate and high K level users. It provide excellent energy response and is an ideal foot for longer residual limbs or where additional components are required.

Key Features

  • Low profile foot with e-carbon springs
  • Lightweight and easy to finish
  • Tripod design with split toe
  • Ideal for longer residual limbs or where additional components are required
  • Sandal Toe Foot Shell

Foot Shell and Glide Sock included.

Esprit 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
