WalkOn – stabilizing and lightweight

Lightweight and discreet

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

Use regular footwear

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

Enhanced safety

You gain safety because the WalkOn supports and lifts your foot during 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.

Walk more naturally

The special material stores energy when you step down with the heel and releases it again during the rollover movement of the foot. This makes walking more natural for you – regardless of whether you walk slow or fast, or how much weight you put on the foot.

Robust and durable

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

People with permanent drop foot depend on a device that lifts their foot while walking. This is precisely what the WalkOn Trimable does. It helps to elevate the foot during the swing phase, making the gait safer again 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. The ankle-foot orthosis is made of a modern carbon fiber prepreg material which is very lightweight. A carbon spring at the back extends from the Achilles tendon to the calf. For users with residual musculature, the WalkOn Trimable provides support while walking. The orthosis releases previously stored energy at toe-off so the gait becomes smoother. The ankle joint is stabilized at the same time.
