Vari-Flex XC Rotate

Vertical forces generated at heel contact are stored and translated into a linear motion described as Active Tibial Progression. This action reduces the need to actively push the body forward using the contralateral foot and also equalizes stride length.

The Carbon-X Active Heel stores the energy during loading response as the amputee transfers his or her body weight onto the prosthetic foot. Energy is gradually released from the heel providing optimal return for forward progression of the limb.

The EVO (Energy Vector Optimization) feature is generated by controlling how the ground reaction force is transferred to the prosthetic foot. Each step is optimized through the magnitude, placement and direction of forces for maximum efficiency. EVO enables the amputee to develop the most natural gait progression possible which reduces fatigue and puts less pressure on the sound side.

The full length keel/toe lever matches the length of the sound foot, providing improved support to the prosthetic limb during late stance. It ensures that users spend equal time on the prosthetic foot and natural limb, thus providing improved walking dynamics and reduced impact to the sound limb.

The layering of carbon fibre, optimised through extensive computer analysis and mechanical testing, ensures that the deflection of the carbon fibre heel and forefoot components are proportional to the user’s weight and impact level.

Trunk rotation is essential for good gait dynamics. If rotation is limited by loss of joints and the prosthetic interface, gait dynamics and comfort are compromised. Rotational forces are translated to more proximal joints and to the residual limb. Rotary torque absorbing components assist in restoring rotation thus improving joint health, comfort and gait dynamics.

A split toe feature allows the foot to adjust to uneven surfaces, allowing amputees to walk with stability and comfort on uneven ground.

The vertical shock pylon reduces impact to the residual limb, joints and lower back during daily activities. It also ensures a more energy-efficient gait by minimising vertical displacement of the centre of gravity.
