WalkOn Flex

Greater flexibility while walking

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

This is precisely what the WalkOn Flex 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.

Thanks to the material (glass and carbon fiber composite) and special design, the WalkOn Flex is particularly suitable if you are looking for more flexibility in the ankle joint and knee. If you have sufficient residual musculature – your doctor or O&P professional will provide you with detailed advice regarding this – the WalkOn Flex will give you good support, especially on uneven surfaces.

Available in sizes for children and adults.

Flexibility for you

Provided the physical requirements are met, the WalkOn Flex enables more mobility in the ankle joint and knee. This makes it easier for you to walk on uneven surfaces. The orthosis also provides moderate support during the rollover movement – just the way you need it.

Moving naturally

You can move naturally with the WalkOn Flex. When you crouch down or climb stairs, for example, you can put a natural load on the forefoot. The WalkOn Flex is perfectly suited for many everyday situations.
