bow® – customized
for the perfect fit
Next-level of foot orthotic treatment.
In this assembly instruction, we would like toprovide a few hints that are helpful for further
processing of bow orthotics.
If you comply with the instructions, the entire
functional range of bow will be guaranteed.
You can thus elicit the best possible treatment
results.

Sanding
Tips for processing the blank
The outline of bow can be trimmed by sanding off the polyamide material.
The length of bow should be one to two millimetres shorter than the original inlaythat comes with the footwear.
• The outline can only be adjusted slightly.
• No changes must be made to the connecting piece (“tendon”).
• We recommend using an 80 grit sanding belt.
Recommendations: see dotted lines

We strongly recommend that the underside of the bow orthotics (plantar connection
element between heel and forefoot area – the “tendon”) is not processed at all. It
should neither be sanded, nor should it have supplementary material attached to it.
Any change to this area may result in the orthotic’s breaking, as forces and torques,that this element was designed to withstand, occur during any pattern of motion.

Processing the underside of the bow is not permitted.

bow Assembly Instruction • 5The general thickness of bow may not be impaired. With the strength of its tendon, thebow constitutes a functional unit. Removing material would weaken this significantly
and could lead to breakage.

This means that grinding indentations, e.g. for heel or forefoot pads, or taperingof the forefoot area, are NOT permitted.

To deburr the edges, we recommend that a polishing wheel is used.

Avoid removing material.

Thinning the profile of the bow is not permitted.

Attachments
Tips for processing the blank
The upper side of bow can be altered optionally with various components, known infoot orthotic treatment.
medi recommends that only bow specific components are used for customizations.
These components have been designed in accordance with the form and function ofthe bow. Using bow support, bow pad and bow cover components will not impair
the functionality of this foot orthotic concept. In addition, you do not need to apply
any liquid glue: the bow components are equipped with an adhesive film that meetsthe requirements of the bow’s blank material.
With help of templates, you can determine the position of the bow support parts, as
intended for common foot proportions. Please use a 1:1 image of the plantar foot, e.g.
a 2D foot scan, to mark the positioning on the bow components correctly andindividually for each foot. By doing so, precise positioning of the elements isguaranteed.

transparent templates
that show the basic
outlines of the bow andthe bow support parts inthe relevant size areavailable for you.

The best bonding is elicited when:• The bow is free of grease and dust,• You roughen the surface of the bow support elements slightly before applying them,• You remove the protective film carefully and do not touch the adhesive side,• You hold the support components in the desired position when affixing them,
applying pressure manually for a few seconds.

The overhanging material of the bow supports can be cut to size using scissors; aftercutting, you can sand the parts in order to adapt their thickness and shape. This can beperformed using various grinding tools or a polishing wheel.
The adhesive film takes full effect after approx. 24 hours. Therefore, we recommend thatthe adhesive not be put under too much stress directly following application.
When using bow pads and bow supports, these should be protected with a bow cover.

If the bow support toe element
is used, the full sole pad, bow
pad complete, should not beused, as otherwise the volumeof the shoe’s toe box will bereduced. In this instance, we
recommend using the bow padheel and bow pad forefoot (seeimage section) at maximum.

bow® covers
Two different bow covers are available.
• The hexagon grey cover is very thin and can easily be applied to any topography;
it hugs every contour perfectly. When grinding the bow’s covered outline, work
must be carried out slowly with a clean sanding belt in order to minimize fraying.
• The petrol HydroFresh cover is slightly thicker and can absorb and release
up to eight times its own weight in moisture. It responds well to sanding.
• We recommend using an 80 grit sanding belt for both cover options.

Shelf life
• The bow is only suitable for people who weigh up to 120 kilograms.
• The full functional scope of the bow is maintained for a service life of at least 1,000 kilometres.
Function may weaken after this distance has been achieved.
• After very heavy use within a short period of time, for example if the wearer takes part in a
marathon, we recommend that the bow orthotics be left to rest for 24 hours so that theviscoelastic material can recover.
