Classic Sport

Model A3

A simple yet very effective functional orthosis. Durable and supportive device that can fit in almost any shoe.


  • Classic biomechanical design
  • ¾ length to metatarsal heads
  • Durable design
  • Classic rearfoot control
  • Premium, Medical Grade, Polypropylene Shell


The Classic Sport device has all the durability and support of A1 All Sport, but the top cover terminates just proximal to the metatarsal heads. This makes it an ideal option for athletic-style shoes without removable insoles. An extrinsic or intrinsic rearfoot post can be customized depending on the patient’s shoe type and use.

This device effectively controls overpronation and supinatory movements. The medial border of the shell bisects the tibial sesamoid and the lateral aspect of the shell bisects the fifth metatarsal head. It also includes a standard 10mm heel cup, vinyl top cover, and extrinsic rearfoot post that can be posted per the practitioner’s discretion.

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