Neutral subtalar insoles, also known as neutral equinovalgism insoles, are custom orthopedic devices designed to correct the orientation of the subtalar joint (located between the talus and the calcaneus) and promote proper alignment of the foot.
The subtalar joint is important for foot stability and movement during walking. In certain conditions, such as pronated flat feet or cavovarus feet (with a very high arch), the joint may be tilted or deviated from its neutral position, causing stability and functionality issues with the foot.
Neutral subtalar insoles are custom-made for the individual and have a specific design to correct the angle of the subtalar joint. This helps restore neutral alignment of the foot, improving load distribution, stability, and functionality.
The use of neutral subtalar insoles may be prescribed for various conditions, including:
Pronated flat feet: Pronated flat feet are characterized by a lack of proper arch curvature and excessive internal rotation of the foot. Neutral subtalar insoles can help stabilize the subtalar joint and improve foot alignment.
Cavovarus feet: Cavovarus feet are characterized by excessive arch curvature and foot inversion. Neutral subtalar insoles can help correct the orientation of the subtalar joint and promote more neutral alignment.
Subtalar joint dysfunctions: In cases of instability or deviation of the subtalar joint, regardless of foot arch type, neutral subtalar insoles can be used to provide support and correct alignment.
