Chose the type of posting you prefer if you want something other than the standard. Standard posting are always in the products description. Chose either “Post to Cast” or indicate the number of degrees correction for both the forefoot and rear foot. If you check “Post to Cast”, we will post the forefoot to the degree measured at heel vertical and then the rear foot is posted at vertical. The exception to this rule is when the rear foot measures more than 9 degrees varus or 6 valgus. We will not post the forefoot more than these limits unless you tell us to do so. In this case, the rear foot will be posted to the forefoot.“No Posting” does not mean vertical. It means there will be no intrinsic nor extrinsic posting, but simply a rounded shell at the rear foot.

Globus Foot Orthotics Extrinsic: This traditional method of forefoot posting is accomplished by placing acrylic or crepe directly under the front of orthotic, wedging the forefoot into its neutral or desired position. This type of posting may not allow the metatarsal heads to reach the supporting surface inducting jamming at the metatarsophalangeal joints. This type of posting also adds considerable bulk to the front of the orthotic, sometimes causing fitting problems.
Globus Foot OrthoticsExtrinsic long metatarsal: An extrinsic forefoot post is added under the metatarsal heads tapering off distally becoming incorporated into a forefoot extension. This posting is most useful when controlling forefoot varus or valgus in sports where heel contact is short or there are large amount of side-to-side motion in the activity.
Globus Foot OrthoticsIntrinsic: Globus orthotics Lab is unique in that our forefoot varus posting starts at the navicular tuberosity and gradually drops down to the supporting surface. In forefoot valgus, the post begins behind the fifth metatarsal at the cuboid gradually extending to the supporting surface. This effectively posts the midtarsal joints allowing the metatarsal to plantarflex to the supporting surface decreasing jamming of the metatarsophalangeal joints and preventing the forefoot post from affecting the plane of the rear foot.
Globus Foot OrthoticsRoot type intrinsic: A more abrupt form of forefoot posting where the post begins at the mid metatarsal level and abruptly drops down to the supporting surface. As originally described by Dr. Merton Root, this technique omitted the first ray by cutting out the medial side of the orthotic. Because this makes the forefoot appear narrow it is seldom made in this manner. It is a similar method to extrinsic forefoot posting, but eliminates the bulk of added material under the leading edge of the device.
Globus Foot OrthoticsExtrinsic: A traditional method of posting with acrylic or crepe applied directly to the heel seat of device. When posting the rear foot extrinsically it is important to keep in mind that all rear foot extrinsic posts begin from heel vertical. This can lead to increased amount of rocking and instability in the orthotic and breaking of the device. Normally a three to four degree pronation skive is added to the bottom of an acrylic extrinsic rear foot post to aid normal midstance pronation.
Globus Foot OrthoticsModified intrinsic: The shell of the orthotic is ground at the heel contact point either to the plane of the forefoot or in desired degree of rear foot varus. The amount of posting is depended on the thickness of shell and is limited. This posting is available on TL-2100 and TL-Silver, but only when posted to vertical.

Of course, these items will vary somewhat depending upon the individual casts, but to give some idea of how much plaster fill will be added to the positive cast and how the orthotics will be ground, we have the following approximations.
Arch Height:
(adult foot)

Our Standard >
No Arch fill:

A minimal amount of plaster is added to the transition between posting platform and arch.
Approximately 1/8” fill
Approximately 1/4” fill
Approximately 1/2” fill
Note: If patient has a naturally low arch which is reflected in the cast there is no need to order “low arch” because we would still add 1/2” fill.
Our Standard >
Shell encompasses all metatarsal heads 1 - 5.
Shell bisects 1st metatarsal head.
Shell bisects 1st metatarsal head and 5th metatarsal head.
Note: Choose “narrow” for dress shoes and “wide” when maximum control is desired.
The following list provides suggested heel cup heights for various categories of patient. The heights given represent the internal heel cup heights:
Males wearing up to 1 inch heels - 15 mm
Children to teens minimum 12 mm
Females wearing: 1 inch heels or lower 12 mm.
1-1 ½ inch heels 8-10 mm.
above 1 ½ inch heels 0-5 mm.
Note: The application of a rear foot post is not recommended on orthoses that are used in footwear that exceeded a 1 ½ inch heel heights.
