Ottobock WalkOn Flex

The Ottobock WalkOn Flex is ideal for drop foot with no more than mild to moderate spasticity, e.g after stroke, traumatic brain injury in multiple sclerosis, neural muscular atrophy, peroneal palsy etc. The Ottobock WalkOn Flex provides the user with a dynamic and physiological gait, natural heel strike and an increase in step length and walking speed.

Who Can Benefit From The Ottobock WalkOn Flex?

The Ottobock WalkOn Flex Is designed for mild to moderate foot drop caused by:

  • Stroke
  • Multiple sclerosis
  • Neural muscular atrophy
  • Peroneal palsy

The Ottobock WalkOn Flex is especially appropriate when the ability to lift the foot decreases during activities (muscle exhaustion). The Ottobock WalkOn has been especially designed for the needs of active people. The support is made of carbon fiber, which makes it exceptionally light but very stable and durable. The Flex version of the Ottobock WalkOn range also reduces pressure on the ball of the foot.

The Ottobock WalkOn Flex prevents foot slap, gives good foot lift (clearance) and offers smooth roll-over in the heel and forefoot zone. Energy is stored and used in the swing phase. A stable shoe together with the medial strut prevent supination and the the user is provided with a slight outward rotation of the foot during swing phase.

Features and Benefits of the Ottobock WalkOn Flex:

The heel and the anterior part of the foot are flexible for a more dynamic and natural gait pattern – on both even and uneven surfaces. In contrast, the middle foot area and calf band are designed to be stable in order to efficiently support lifting the foot.

At the end of the swing-through phase, your foot is dynamically guided back so that you can once again step comfortably with your heel at the start of the standing phase. The energy stored during the heel impact is released when you push forward with your toes. Therefore you have to expend less energy for walking and can cover longer distances without problems. 

This orthosis is light and slim, so that it fits inconspicuously under clothes, unlike some foot drop supports. The removable calf pad increases the level of comfort.

You should wear the orthosis in a sturdy shoe. We recommend that you place the orthosis into the shoe first and then insert your foot. The orthosis then acts like a shoehorn. You should ensure that the hook-and-loop tape used to attach it to the lower leg is sufficiently tight. This allows you to prevent unnecessary movement and possible friction.


The Ottobock WalkOn Flex can easily be cut down to fit in a particular set of shoes, so you can get the exact fit you need. The Flex is available in a range of different sizes to suit your needs.

Our Guide to Finding the Perfect Size and Fit

Using Your Shoe Size

For most of our insoles, the easiest way to find the best size for you is to go off of your current shoe size. The majority of our insoles are available in a range of sizes and you can simply select the size that best fits your existing shoes.

Please be aware that, as with shoes, there can be slight variations in the size of insoles. For example a size 8 of one brand might not be exactly the same size and width as the size 8 of another. To help account for these discrepancies, a number of our insoles include dimensions to help you ensure you're getting the right size.

Measuring Your Current Insoles

While using your shoe size to find your best size is a good guide, it is not always foolproof. If you want to guarantee that your insole fit your shoes as closely as possible, we recommend measuring your existing insole and using this as a guide to your size.

To do this, please follow the steps outlined below:

  1. Remove the existing insole from the shoes you wish to use your new insoles with (please note that not all insoles are removable)
  2. Measure the insoles at their longest and widest points (see the below diagram for an idea of where this will be
  3. Match the measurements to the dimensions of the insoles listed, and choose the size that best fits your results

How to measure your insoles

Where Can I Find the Dimensions?

The dimensions for insoles can be found on the "Product Details" tab (please see below) and are usually found in the sizing section of the listing, in a table. Please be aware that not all products currently have the dimensions listed.

Product Details Example
The dimensions of insoles can usually be found on the "Product Details" tab

What If There Are No Dimensions Listed?

If you do not see the dimensions listed on the Product Details tab, please fill in the form below and we will work to get the relevant information as quickly as possible. We will email you once we have the information that you have requested.


Trimming Your Insoles to Fit

To get the ultimate level of fit from your insoles, you can trim them to make a small adjustment. To trim your insoles, simply follow the steps below:

  1. Remove your existing insoles from your shoes
  2. Line up your existing and new insoles at the heel
  3. Trace the outline of the insoles against the new pair at the toe end (see the image below for an example)
  4. Carefully cut along the traced line
  5. Your insoles should now fit your shoes better

Trace the outline of your existing insoles
Carefully trace the outline of your insole

Please note that not all insoles are suitable for trimming. Most insoles are unsuitable for return once they have been trimmed to fit; we recommend bearing this in mind prior to trimming.

If you would like a more detailed guide to trimming your insoles, please read our full guide on How to Trim Your Insoles.
