WalkOn Reaction Lateral

Dynamic appearance

People with permanent drop foot depend on a device that lifts their foot while walking.

People with permanent drop foot depend on a device that lifts their foot while walking.

That is precisely what the WalkOn Reaction lateral does. The carbon orthosis helps to elevate the foot during the swing phase, making the gait safer while reducing the risk of stumbling and falling. The tip of the foot no longer gets caught as easily on small obstacles or uneven ground.

Thanks to its special design, the WalkOn Reaction supports the knee joint as well. When the foot lowering muscles are impaired as well, you also benefit from the high energy return of the orthosis, which is activated during the rollover motion of the foot. This lets you walk more naturally again.

Benefits at a glance

WalkOn Reaction Lateral – lightweight, stabilizing, robust

Konfektionsschuhe tragen
Use regular footwear

The orthosis fits in any shoe that provides support. You only need to make sure that the shoe has a reinforced heel. To put on the orthosis, position the WalkOn Reaction lateral in the shoe and then slide your foot in

Leicht und dezent
Lightweight and discreet

The WalkOn Reaction lateral is lightweight, slim and discreet under clothing. A shin pad makes it even more comfortable for you.

Mehr Sicherheit
Enhanced safety

The WalkOn Reaction lateral enhances your safety by supporting and elevating your foot during the swing phase while walking. This reduces the risk of catching the tip of your foot on carpet edges or uneven ground, for example.

Natürlicher Gehen
Walk more naturally

The WalkOn Reaction lateral promotes a largely physiological gait. Depending on your current phase in the gait cycle, the special orthosis design (frontal support element) supports knee extension and flexion. Your gait pattern becomes smoother.

Robust und langlebig
Robust and durable

The WalkOn Reaction lateral is especially robust. Its has proven its durability in tests and long-term functional testing. The adult sizes were tested for 2 million cycles (= steps), the child sizes for 1 million cycles (= steps).

Weniger Ausgleichsbewegungen
Fewer compensating movements

Compensating movements can lead to signs of wear. The WalkOn Reaction lateral reduces this thanks to its high energy return. You walk more symmetrically because the orthosis stores energy at heel strike and releases it again during the rollover movement of the foot.
