Orthosis Style provides a reference as to how the foot orthosis will be finished in a laboratory environment.

For Machined EVA orthoses the Orthosis Style is achieved manually, not within computer-aided design.

Full Length

A Full Length orthosis will be shaped to the selected Orthosis Size (US Foot Size) and Orthosis Top Width (US).

If Refer to Insole Template is selected from the To Fit Shoe option list then a note will be provided on the prescription to refer to this attached template.

3/4 Length

A 3/4 Length orthosis will be modified to end proximal to the MPJ's. This adjustment is often requested when footwear is narrow, or shallow distal to the MPJ's.

Please be aware of any orthosis modification option that extends distally to the MPJ's may be adversely affected by requesting the 3/4 Length option.

Sulcus Length

A Sulcus Length orthosis will be modified to end distal to the sulcus of the foot. This adjustment is often requested when footwear is narrow, or shallow distal to the sulcus.

Hook/Cobra

A Hook/Cobra orthosis will be modified to end proximal to the MPJ's. In addition, the lateral arch and centre of the heel will be removed. This adjustment is often requested when the orthosis requires fitting in a women's dress shoe (e.g. - high heeled shoe).

Sizing Style

Sizing Style defines the particular sizing classification for Machined EVA orthosis manufacture.

There are several default options, which are listed below.
