Quadrastep A Orthosis

The A QUAD Foot-Type is commonly thought of as an over-supinated or severe Pes Cavus foot. This condition, also known as a Torque Foot, occurs when an Uncompensated Rearfoot Varus is coupled with a Large Rigid Forefoot Valgus.

We fondly refer to this foot-type as our "chandelier shakers"! Why? Because this foot-type loads heavily on the ground and never seems to pronate, leading to poor shock attenuation.

The development of heel and lower back pain is common. The torque foot nature of this foot-type allows the valgus forefoot to offset the uncompensated inverted heel alignment that would normally lead to a toe out gait pattern (see C Quad foot-type). Overall, the foot progression angle for this person is such that the feet point relatively straight ahead during gait (no toe out) with a narrow base of support, much like a tight rope walker.
