Medial Arch
A built-up fill along the medial longitudinal arch that increases contact and support for a snugger, more controlling fit.
How it works
The medial arch fill raises the shell to meet the patient's medial longitudinal arch, turning empty space into contact. Total contact spreads force over more surface, cuts peak pressure elsewhere, and gives the midfoot a platform that moves with it rather than a void it falls into.
There's also a proprioceptive dividend: an arch the foot can feel changes how the patient loads it. Support height is a comfort variable as much as a mechanical one, which is why it's prescribed, not fixed.
When to prescribe it
- Flexible pes planus needing full-contact support
- Arch fatigue in long-standing occupations
- Plantar fasciitis where midfoot contact reduces band strain
- Athletes wanting a more connected, responsive fit
- Any Rx where the standard contour leaves the arch unsupported
How we build it
You set the fill height against the scanned arch and watch it render live on the model. The result is a smooth, continuous medial profile matched to that foot, not an arch “size”.
