Orthosis Style

Default Style	Available Styles

Default Style	Available Styles
Full Length	Full Length
	3/4 Length
	Sulcus Length
	Hook/Cobra

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.

Please be aware of any orthosis modification option that extends distally to the sulcus may be adversely affected by requesting the Sulcus Length option.

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).

Please be aware that the entire lateral arch will be removed when selecting Hook/Cobra. If you intend to provide lateral wedging within your orthosis then this will be adversely affected.

Sizing Style

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

There are several default options, which are listed below.

Our LaserCAM Orthotics sizing templates may be purchased to assist with accurate sizing.

Men's (Wide)

This selection denotes a Men's US sizing convention that is specific to LaserCAM Orthotics computer-aided design software.

The dimensions below are subject to minor manufacturing variability.

Orthosis Size (US Foot Size)

Remember to size the orthosis based on both the length and the width of the foot.

Orthosis Size (US Foot Size) defines the size that will be used during computer-aided design and computer-aided manufacture.

Sizing Convention	Minimum Size	Maximum Size

Sizing Convention	Minimum Size	Maximum Size
Men's (Wide)	4	17
Women's Athletic (Medium Width)	4	13
Women's Dress (Narrow Width)	4	13

Est. Orthosis Length is displayed below the Orthosis Size (US Foot Size) input. It is commonly recommended that the Est. Orthosis Length be at least 25mm greater than the length of the foot.

Sizing Conversion (Length)

A sizing conversion chart has been provided below to assist with LaserCAM Orthotics sizing.

The dimensions below are subject to minor manufacturing variability.

Orthosis Thickness

Orthosis Thickness specifies the thickness of a Machined EVA orthosis at it's thinnest regions. These regions are most commonly the forefoot and centre of the heel.

Default Value	Minimum Value	Maximum Value

Default Value	Minimum Value	Maximum Value
1.5mm	1.0mm	10mm

You should consider Orthosis Thickness in conjunction with EVA Density and Patient Weight.

Orthosis Top Width (US)

Orthosis Top Width (US) provides a reference for the width of the Machined EVA orthosis.

The default selection mirrors the selection of Orthosis Sizing (US Foot Size).

Not requesting a specific Orthosis Top Width (US) may result in orthosis that are too narrow, have incorrect heel cup height, heel cup depth, and poor conformation to medial and lateral longitudinal arches.
