The A Quad foot type is an over-supinated or cavus foot type with the following features:
Also known as a Torque Foot due to rearfoot varus and forefoot valgus.- Largely inverted heel alignment from Uncompensated Rearfoot Varus
- High arch (Cavus)
- Poor shock attenuation caused by heavy loading and never seeming to pronate.
- Excessive pronation throughout gait cycle.
- Narrow base of support or cross over gait, like walking on a tight rope.
- Calluses may form to the 1st metatarsal and 5th metatarsal.
- Approximate presentation in US population is 15%.
The Quad A foot type is often diagnosed as "Pes Cavus" (High Arch) in adults and is rarely seen in young (<7 years-old) children without a neurologic etiology.
CHILD PRESETATION: This is usually not painful in children, but can commonly lead to unstable or recurrent ankle sprains.
