Ergonomic foot arch support insoles designed specifically for women's footwear (US sizes 5–9 / EU 35–39). These lightweight, contoured orthotic inserts feature a U-shaped design with targeted perforation zones for breathability and pressure relief on the medial longitudinal arch. Made from flexible yet supportive thermoplastic elastomer (TPE) or EVA foam, they provide subtle elevation and stabilization without adding bulk—ideal for flats, low-heeled shoes, or sneakers where extra cushioning is needed. The smooth matte black finish ensures discreet wear under most shoe linings. Perfect for daily wear, office settings, or light walking; helps reduce fatigue and mild overpronation. Not medical-grade orthotics but suitable for preventive comfort enhancement. Easy to trim for custom fit (instructions typically included). Pack includes one pair (2 pieces).
