Body Geometry Insoles are ergonomically designed and scientifically tested to increase power, endurance, and comfort by optimizing hip, knee, and foot alignment. These insoles have been scientifically proven to increase power and reduce injury by aligning hip, knee, and foot. The insoles feature customized longitudinal arch and metatarsal support available in three contour options: Red+, Blue++, or Green+++. A proprietary lightweight foam construction avoids taking a compression set for long-lasting performance. For maximum performance benefits, Body Geometry insoles can be combined with Body Geometry shoes and wedges.
