Trace, Trim and Walk Away!  The WalkOn Flex 28U22 and the WalkOn Trimable 28U23

- The sensation of pressure is lighter on the ball of the foot than with the standard WalkOn design

WalkOn Trimable 28U23

Physiological Gait Pattern

The flexible elements in the anterior foot area and the heel make a dynamic physiological gait pattern possible for your patient, both on even and uneven surfaces, while the middle portion of the foot and the calf band are held in place in order to actively support lifting the foot.

Gait analysis studies have shown that, compared to other carbon orthoses with frontal contact in the stance phase, the WalkOn® offers increased stability for the patient. During the swing phase, the orthosis compensates for the missing foot lifter function in an almost identical manner. The improved rollover dynamics can be verified by examining the torque acting on the upper part of the ankle. Near-sagittal torque was measured on the upper part of the ankle in the middle of the stance phase. This relates to a physiological stress on the joints and a high level of comfort. For more information, see the links below.

In addition, the WalkOn® with its removable calf pad stands out with a high level of user comfort. The lightweight design and slim anatomical shape increase compliance and make a dynamic gait at higher speeds possible for your patient. It also makes this a durable solution for your patients. Patients will also appreciate how easy it is to don and doff this AFO.

"I received the WalkOn® AFO yesterday for a dropped foot from a back injury suffered three years ago.

For three years I have been dragging, my foot making it difficult to walk extended intervals. In one day, I was able to walk from the parking lot of our local mall and all around the inside without any symptoms of fatigue or being tired.

It is so great to be able to walk without worrying about tripping or falling because of my dropped foot. This has opened my life again to do things I only imagined I would be able to do again. I hope more people learn about this great product and achieve the freedom I have found again.

So far, I have tried the WalkOn® AFO in top siders, tennis shoes and sandals. On Sunday, I will try the walk on with dress shoes going to church.

Thank you so much for giving me the freedom to walk with confidence and to be independent and free to do things I love to do."
