Ultra Slim

Model L3

Lightweight and supportive carbon fiber orthosis. Designed to fit in narrow men and women’s dress and fashion footwear.


  • Super Thin Design
  • Premium Carbon Shell
  • Lightweight


The Ultra Slim is a classic, low-profile, metatarsal-length device designed for use in low-volume shoes. A carbon shell keeps this orthotic model thin and lightweight while still providing excellent support. A shallow heel cup and vinyl top cover contribute to the thin design, allowing the device to fit in narrow and fashion shoes. The shell can be constructed to be either flexible or rigid upon request.

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