How Orthotics Work
Foot and lower limb injuries often occur when the foot’s capacity to pronate and supinate is compromised. The foot safeguards the body from impacts during activities like walking and running by pronating (rolling inward) and supinating (rolling outward). Medical-grade orthotics minimize the impact of each stride by supporting the foot in resisting pronation and facilitating supination.
Design Elements that Counteract Pronation
When the foot strikes the ground, it rolls inward and the arch flattens. Lower leg muscles support the foot by maintaining the arch, preventing excessive inward rolling that can cause pain and injury. Both Interpod and Custom Orthotics alleviate strain on muscles, tendons, and ligaments with a built-in design feature known as the Rearfoot Wedge, which resists the force of pronation.
Design Elements that Encourage Supination
As the heel lifts off the ground, the toes flex, tightening the plantar fascia (via the windlass system) and stabilizing the foot for the legs to propel the body forward. Interpod and custom-made orthotics incorporate design features to promote supination, such as the rearfoot wedge, cuboid notch, plantar fascial groove, and a first cut out.
