Pro-Flex® LP Align

Pro-Flex® LP Align


Pro-Flex LP Align combines functionality, comfort and aesthetic design. It allows users the freedom to choose footwear that best suits their activities, without having to compromise alignment, posture, dynamics or functionality. The heel height adjustment feature is quick and easy to use.

The lightweight anatomical foot cover features a steady-grip sole for barefoot stability on wet or slick surfaces and a sandal toe to accommodate a range of footwear. The spaced sandal toe easily clamps onto sandals and flip-flops held by the toe.

Pro-Flex® LP Align Features

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.

Heel Height Adjustability

Heel Height Adjustability

Heel height can be adjusted for various types of shoes to ensure correct alignment. Users can easily change shoes to fit most occasions as the heel height can be adjusted within the given range.

Benefits: Adjustable heel height minimizes misalignment of the prosthesis thus reducing walking fatigue and discomfort experienced with poor alignment.

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.

Sandal Toe

Sandal Toe

Sandal toe foot designs incorporate a split between the first and second toe.

Benefit: More anatomical look for increased visual appeal and more functional compatibility with sandal shoes.

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.
