Model A8

The most intimately contoured arch. Flexible shell provides dynamic support during gait.


  • Dynamic arch support
  • Progressive arch rebound and control
  • Mass theory arch support
  • Premium, Medical Grade, Polypropylene Shell


The Dynamic Arch Support (DAS) device is optimized by using a casting technique that captures the patient’s highest possible arch profile. Casting with impression foam allows the foot to be captured in its most supinated position, yielding an orthosis with the most intimate arch control. The device is then calibrated to have a more flexible shell based on the patient’s weight, allowing for a more comfortable and natural stride compared to traditional rigid orthotics.

Developed on the principles of modern mass-theory, this device features a flexible polypropylene shell that rebounds following the midstance phase of gait. It is also finished wider than standard orthotics, providing support across the entire plantar surface of the foot.

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