The next step to reliable, natural movement

If you lost a limb quite recently or, because of age or fitness issues, you tend to walk quite slowly most of the time, you’ll understand how important it is to feel steady on your feet and walk as naturally as possible.

The Balance Foot J prosthetic foot from Össur is designed to meet those requirements and get you moving.

A lightweight solution, the Balance Foot J draws on innovative and proven Flex-Foot technologies. It incorporates a cushioned heel for stability and added comfort when your heel touches down on the ground, and the unique EVO feature helps to promote an easy, natural motion as you roll over the centre of the foot onto your ‘toe’.  Then as you push off onto your other foot, the foot’s carbon composite toe ensures a lifelike boost of energy to help you move forward.

All in all, it offers an effective combination of stability and more natural and fluid movement.

Who Balance Foot J is for:

  • People who tend to walk quite slowly most of the time, or who may have lost a limb quite recently
  • Suitable for those with below-knee or above-knee* amputation, weighing up to 300lb (136kg).

*Works well in combination with the Total Knee 2000 from Össur.

Balance™ Foot J 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.

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.
