Subo-Flex LP

Model L4

Built for all day comfort in low volume shoes.  Provides semi-accommodative support.


  • Mild Control of Midtarsal Joints
  • Accommodative Support
  • Premium, Medical Grade, Subortholene Shell


The Subo-Flex LP provides the same accommodative support as the standard Subo-Flex but in a low profile version. It is ideal for active patients seeking comfort for low-intensity activities while wearing low volume shoes.


This device has a unique subortholene shell that is available in 2mm, 3mm, 4mm, or 5mm thickness and provides accommodative, flexible support.  The shell will shape over time to fit the contours of the patient’s foot upon pronation and supination. An EVA arch fill acts as a rearfoot stabilizing post while simultaneously reinforcing the arch, increasing shock absorption and control for a variety of pathologies.

The Subo-Flex LP is constructed with a positive model of the patient’s foot and can be modified at the practitioner’s discretion.
