2 Handling
2.1 Size Selection of the product
The size selection of the orthosis is based on the shoe size. Left and Right. Small, Medium, and Large.
2.2 Adapting and Applying the product
1. Shoe selection: to obtain best effect of the In Step AFO, the user needs to wear a stable, laced shoe
with a firm heel counter. The heel height should be 1,0 cm (+/-5 mm) / 0,4 inches (+/-0,2 inches).
2. Pick out correct size from the size chart.
3. Adapt the In Step AFO into correct size: If the user has a removable inner sole in his/her shoe, use
that for marking the correct size on the footplate. (pic. 1), or draw a line around the user’s foot
directly on the foot plate.
4. Grind the foot plate by use of a grinding machine into correct size (according to the line on
the foot plate), and avoid grinding into the carbon. When adjusting the foot plate width; grind on the lateral
side but not more than necessary, to avoid the medial part/the insert to slide in the shoe and to avoid
pressure on the medial malleoli (pic. 2). When adjusting the length of the foot plate, focus on grinding the
back of the foot plate, then the insert will automatically be positioned behind (posterior) the medial
malleoli which prevents pressure on the ankle and malleoli (pic. 3).
5. The shell can be adjusted by grinding, if necessary. Never modify the upright or around footplate
attachment.
6. In the event of sharp edges at the orthosis, smooth them out by grinding the edges in water
with wet/dry sand paper.
7. If the user has a foot deformity, correct it with a corrective insole or a custom molded device.
(If the foot cannot be corrected by an insole, the orthosis and a stable shoe, a IN STEP AFO should
not be used).
8. Apply the textile part on the calf part of the orthosis (pic. 4).
9. Cut the soft Velcro part at a proper length. To assure a good attachment, the soft Velcro should not be
more than 2 cm longer than the hard Velcro, when the calf band is attached around the user’s calf.
