Orthotic Insole Cross-Section Diagram | Foot Support Anatomy #3672370 (License: Personal Use)

This illustration depicts a medical-grade orthotic insole in cross-section, revealing three distinct functional layers: a rigid or semi-rigid base layer for structural support, a mid-layer with targeted arch elevation, and a soft top cover for comfort. The deep heel cup stabilizes rearfoot motion, while the contoured arch area provides biomechanical correction for overpronation or flat feet. The gradient shading emphasizes density variation for pressure redistribution.

Used on podiatry, orthotics, and footwear product pages to educate patients or customers about internal construction and therapeutic benefits; matches user intent for understanding how orthotics work anatomically.
