WalkOn Reaction

Also supports the knee joint

People with permanent dorsiflexor weakness depend on a medical aid that lifts their foot while walking.

That is precisely what the WalkOn Reaction does. It helps lift the foot during the swing phase, so that the gait becomes safer while the risk of stumbling and falling is reduced. 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 musculature is impaired in addition, you also benefit from the high energy return of the orthosis, which is activated during the rollover motion of the foot. You walk more naturally again.

Lower leg shell with shin pad

The shin pad is on the lower leg shell. It consists of a climate control material (Outlast) and can be easily applied to the leg with a hook-and-loop fastener. The user benefits from improved hygiene and pleasant wearer comfort.

Medial spring

Thanks to the medial spring, the WalkOn Reaction stores energy during the heel strike and releases it again with the rollover movement. It features a high energy return.

Foot component

The foot component ensures the flexible rollover of the foot while walking.

Frontal contact

With frontal contact, the WalkOn Reaction not only lifts the foot, it also supports the knee joint.

Benefits at a glance

Walk more naturally

The WalkOn Reaction enables a nearly physiological gait. Depending on your current phase in the gait cycle, extension and flexion of the knee is supported by the special structure (frontal contact) of the orthosis. Your gait pattern becomes smoother.

Fewer compensating movements

Compensating movements can lead to signs of wear. The WalkOn Reaction reduces these with 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.

More safety

You gain safety because the WalkOn reaction supports and lifts your foot in the swing phase while walking. The risk of getting caught with the tip of the foot, for example on carpet edges or uneven ground, is reduced.

Use regular footwear

The orthosis fits in any shoe that provides support. You should merely ensure that the shoe has a reinforced heel. To put on the orthosis, you should position the WalkOn Reaction in the shoe and then slide in with your foot.

Lightweight and discreet

The WalkOn Reaction is lightweight, slim and discreet under clothing. A shin pad makes it even more comfortable for you. It is made of climate control material (Outlast) which reduces heat development and perspiration.

Robust and durable

The WalkOn Reaction is especially robust. It has proven its durability in tests and long-term function testing.

WalkOn Product Family

There are four WalkOn orthoses. This allows your doctor or orthopaedic technician to select the product that is most suitable for your personal condition and the severity of your paralysis.


  • Dorsal flexor weakness, with or without moderate spasticity. For slight impairment of the plantar flexion muscles, and for slight impairment of knee extension (e.g. constant fatigue of the knee extensors during long periods of standing or walking)
  • For slight impairment of the plantar flexion muscles, and for slight impairment of knee extension (e.g. constant fatigue of the knee extensors during long periods of standing or walking)

The indication frequently occurs after a stroke, traumatic brain injury, multiple sclerosis, neuromuscular atrophy or peroneal paralysis.

  • How do I put on the WalkOn Reaction?

    We recommend that you place the orthosis into the shoe first and then insert your foot. Then you can simply fasten the hook-and-loop closures.

  • Do I need a special shoe for the WalkOn Reaction?

    No, but you should select a sturdy shoe with a reinforced heel. It is important that the orthosis fits firmly so that it moves as little as possible. We also recommend a heel height of 10 mm; alternatively this can be determined by your technician. An additional pair of shoes should of course have the same heel height.

  • Is it possible to take part in sport with the WalkOn Reaction?

    Yes, in fact it is recommended that you are active. Speak to your orthopaedic technician to get their advice on which sports are the most beneficial and how to make the best use of your orthosis. You should however avoid extreme and abrupt movements.

  • How do I care for the WalkOn Reaction?

    The orthosis should be wiped regularly using water and a mild cleaning agent. All pads and closures are combined, and all textile components can be washed and replaced. We recommend washing the pad at least twice a week (machine washable at 40°C).

  • Can I get extra pads for the WalkOn Reaction?

    Replacement pads can of course be ordered through your orthopaedic technician. He or she adapts the pads for you personally to ensure they fit.

  • Can I drive a car with the WalkOn Reaction?

    It is not possible to make any specific recommendation. You must be able to safely control any vehicle for which you require a driving licence and insurance, or which is used in traffic. This ability when wearing a WalkOn Reaction is determined on a case-by-case basis. You are required to observe national and state laws.
