What is lateral ankle instability?

Chronic lateral ankle instability develops after repeated ankle sprains stretch or tear the ATFL and CFL ligaments, leaving the ankle feeling loose and prone to rolling outward — especially on uneven ground.

How EdgeGuard™ helps

EdgeGuard™ uses lateral rearfoot wedging to control supination tendency and shift loading medially, reducing the risk of ankle roll-out and providing proprioceptive input for improved ankle stability with each step.

Why does my ankle keep rolling?

After lateral ankle sprains, ligament laxity and proprioceptive loss create a vicious cycle of instability and re-injury. Orthotics address the mechanical component of this.

Do I still need physiotherapy?

Yes. Orthotics correct mechanics but proprioceptive retraining and peroneal strengthening are equally important for full ankle stability recovery.

Can I use EdgeGuard™ for sport?

EdgeGuard™ is designed for sneakers and athletic footwear, making it suitable for sport activities. It provides passive mechanical support during dynamic movement.
