Mini BladeXT

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

For youngsters, life never stops. An active lifestyle needs to be fully equipped to meet the needs of the most demanding user, whether it’s going to school, spending time with friends, running, cycling or taking part in other sports.

Designed to offer a complete solution, the Mini BladeXT offers outstanding stability, ground compliance and improved comfort through the split toe and traction sole, while its C-shaped toe spring is primed for optimal energy response.

Available in dazzling pink or electric blue, the Mini BladeXT is the ideal choice for children and may be the only foot they need!

Key Features

  • Twin toe and heel springs
  • Split toe design
  • Traction sole
  • Heel stiffness wedge
  • Waterproof
  • Field replaceable heel spring kit
  • Male mini pyramid with 30mm shift and rotation

Key Benefits

Energy Response

The curved toe design works like a loaded spring to assist forward progression. From initial ground strike, the C-shaped curve compresses and stores energy, ready to release upon the next step.

Protection & Stability

With a unique toe and heel design, users feel balanced and secure when standing, running or making a change of direction. This also ensures shock absorption for comfort and protection on every step.

Safety & Compliance

An integral traction sole helps to provide safety and surefootedness for all activities. The split toe improves ground compliance, provides flexibility and enhances comfort on uneven ground.

Lightweight & Strong

The lightweight construction won’t slow you down. Made from e-carbon, the Mini BladeXT is strong and tough, yet flexible and responsive.

MiniBlade XT - Natural Motion

Natural Motion

As the wearer transfers their weight onto the Mini BladeXT, the heel spring compresses, absorbing shock for greater comfort and stability during early stance. This ensures a smooth roll-over phase and seamless loading of the e-carbon toe spring. In late stance, the stored energy is released in a forward direction to spring into the next step. The net result is a more balanced, symmetrical and energy efficient gait.

Mini 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
