Customizing an OTC Insert: The list is endless and limited by our Imaginations!!

Sole is one of the common OTC arch supports I recommend in my office

In this case, the front was just too hard for the patient so I removed it for softer material

The cut or transition was just behind the metatarsal heads (ball of the foot)

Here the Arch only part with be glued onto a full leather top cover. 

Using the original front, the leather can be trimmed to be an exact replica of the original

Now a soft material like 1/8 inch poron is applied as the new front

Customizing OTC inserts: Quick Way to Begin to Change Mechanics

Podiatrists are always designing custom inserts to change a patients mechanics in some way to help their problems. Sometimes that correction is direct (like off loading a sore area seen with the horse shoe shape blue pad), and sometimes that correction is indirect (like the white metatarsal pad to help center the foot). Here I have added 3 adjustments to this Dr Scholl's inserts. The patient initially had the gray appearing heel wedge to help with pronation forces. When the patient returned, both his knee and low back had felt better with pronation control, but he was having new problems with the front 2nd metatarsal. The blue padding was then to help that. Once the inserts wear out, because I take photos of all of these inserts, I am able to re-make them if the patient sends into the office a new pair. Ah, biomechanics!!
