Model A9

Combats and controls supination. Provides support and correction for cavo-varus patients in active settings.


  • Cavus foot balancing design
  • Forefoot and rearfoot correction
  • Premium, Medical Grade, Polypropylene Shell


The Coleman device is designed for the cavo-varus deformity, where the hindfoot is flexible and will return to a neutral position when a Coleman block is placed under the lateral aspect of the foot. This device is designed to combat and carefully correct patient supination resulting from a rigid plantar-flexed 1st ray.

This device incorporates a 3-degree lateral wedge that extends from the heel to the metatarsals. A 3-degree valgus rearfoot post accompanies this wedge to ensure neutral alignment of the foot. A 1st ray cutout and a reverse Morton’s extension have also been incorporated to balance first met head pressure.

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