Theta is the angle of the wedge.

Theta-Orthotics Science:  All devices that control foot function, use wedges to change the way you walk and stand. Proper placement of the wedges during gait compensate for an angular deviation of the tibia. Ultimately the higher the wedge the more change that is created during gait. Theta defines how the wedge is to be measured and ultimately how much change is created in the way you walk and stand.

Theta is the functional angle of the rear foot and forefoot wedges.

morton neuroma plantar fasciitistheta custom orthotics“Functional” orthotics are basically angular wedges, strategically placed so as to change the “specific angle” of support, during weight bearing gait. Patent literature over the last 200 years describes orthotics with two basic types of wedges. Some orthotic designs use both types of wedges, MLA and MET, most use just one. Theta is a Greek Letter used in math to represent the value of an Angle. I use it to define the way the functional wedge is measured in any insole, arch support, or orthotic device.

Theta can be measured in any Orthotic Device.

orthotics use two wedges

The angle of the wedge defines the physical design, in any foot control device, responsible for change in foot and leg function, or the way you walk and stand. Although the optimal angle of correction has been found to be between 27 and 37 degrees for most patients, treatment must begin at tolerable but helpful level, then progressively increased as the body adjusts to the new way of walking and standing.

More Theta equals more change and less Pain.
