Vari-Flex®

Vari-Flex®


HC000997

The Vari-Flex provides an exclusive combination of comfort and dynamics.

The Vari-Flex is light-weight, easy to assemble and has a slender profile which makes it easy to cosmetically cover.

For users it ensures the highest levels of confidence and security. Offering natural gait with less fatigue and ultimately less strain on the lower back and sound side, it is the ideal foot for any activity.

Impact Levels

Impact LevelExample

Low

Daily activities involving gentle, steady walking with the use of a walking aid.

Example: Moving around at home, modest walking in the community.

Moderate

Daily activities involving average walking with the ability to vary speed or walking pattern.

Example: Going to the shops, confident outdoor walking.

High

Daily activities involving fast walking, jogging and climbing stairs.

Example: Heavy-lifting, manual labor, recreational sports.

Vari-Flex® Features

Active Tibial Progression

Active Tibial Progression

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.

Benefit: More natural gait and reduced walking effort.


CARBON-X® Active Heel

CARBON-X® Active Heel

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.

Benefit: Reducing impact to the joints and residual limb thus increases comfort, reduces joint and limb damage.


Full Length Toe Lever

Full Length Toe Lever

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.

Benefit: Improved walking symmetry and reduced impact to the sound limb.


Proportional Response

Proportional Response

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

Benefit: Customized construction optimizes walking efficiency thus reducing fatigue for the user.


Split Toe

Split Toe

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

Benefit: Helps to maintain balance, stability and reduces peak impact during loading.


Waterproof

Waterproof

The use of first-rate material such as carbon fiber, titanium and high-grade aluminum provides permanent protection against harmful ingress of water. Even after submersion in water, the foot’s structural parts maintain their integrity and continue to provide full support, function and durability.

Benefit: No loss of prosthetic function under wet circumstances.
