Not every foot rolls inward. Some roll out. If your child has a high arch and a supinated foot type — known clinically as pes cavus — their weight tends to load along the outer edge of the foot, leaving the arch under-supported and the ankle prone to rolling outward. Standard insoles often make this worse: too much rigid medial support can actually push a high-arched foot further into supination.
The Finn Device is built specifically for this foot type. It’s shaped to make full contact with the high arch — filling the space a flatter insole leaves empty — so the foot is supported through its natural contour rather than propped up at a single point. Just as importantly, it’s designed to stabilize without over-correcting, giving the foot secure, balanced support that helps keep the ankle centered instead of tipping outward.
The result is a foot that feels supported, cushioned, and steady — with better shock absorption for the rigid, high-arched foot and more confidence on the outer edge where supinated feet are most vulnerable.
Key features:
It’s made for people with high arches and a supinated foot type — known clinically as pes cavus. If your foot tends to roll outward and load along its outer edge rather than rolling inward, this device is designed for you.
Supination is when the foot rolls outward and weight is carried on the outer edge instead of being distributed evenly. It usually goes hand-in-hand with a high, rigid arch. Because the arch sits higher off the ground, it’s often under-supported by standard insoles, which can leave the foot less stable and more prone to the ankle rolling outward.
Most off-the-shelf insoles are built for flat or inward-rolling (pronated) feet, and their rigid arch support can actually push a high arch further into supination. The Finn Device does the opposite — it fills the high arch with full contact for support, while stabilizing the foot so the ankle stays centered rather than tipping outward.
It’s designed to improve stability and reduce the lateral (outer-edge) instability that supinated feet are prone to. Many people find it helps them feel more balanced and secure, though results vary from person to person. If you’re experiencing frequent ankle rolling or sprains, we recommend an evaluation so we can confirm the right support for you.
All ages
The Finn Device fits best in shoes with a removable insole and a secure, closed heel — everyday sneakers and athletic shoes are ideal.
