Product Description Material: PU Size: S: 38-40; M: 41-43; L: 44-46 Color: Green, Black Quantity: 1 pair Package Content: 1 x Flat Foot Orthopedic Insole 1. RIGID ARCH SUPPORT & ERGONOMIC DESIGN: These running athletic insoles help align your body by supporting the subtalar joint and preventing overpronation or oversupination. The U-shaped design and deep heel cup cradle the foot with built-in heel support, keeping the foot bones aligned and balanced for improved stability. Provides moderate control and support during walking and standing, offering comfort and cushioning for everyday use. 2. FOOT PAIN RELIEF: These orthotic inserts for men and women provide a high level of arch support. The deep heel cup helps reduce overstretching associated with plantar fasciitis and relieves heel pain and heel spurs. Distributes pressure evenly across the front and back of the heel. Helps alleviate discomfort caused by flat feet (pronation), fallen arches, bunions, arthritis, Achilles tendonitis, and ball-of-foot pain. 3. DURABLE COMFORT MATERIAL: High-quality materials offer excellent shock absorption and pain relief. A rigid TPU support on the back of the insole stabilizes the arch and wraps around the heel for added support during physical activity. The insole's fabric surface helps keep feet cool, while a silica gel cushion under the heel provides durable comfort. The top fabric helps reduce odor and keeps feet feeling fresh. 4. TRIM TO FIT & SUITABLE FOR DAILY USE: These arch support insoles for plantar fasciitis are adaptable and designed to fit a range of shoe sizes. You can trim the insoles for a customized fit. Designed to provide moderate control and support in athletic shoes, work shoes, and boots. Offers comfort and cushioning for various types of casual and everyday footwear. Compatible with most shoes, including running shoes, work boots, high-volume dress shoes, and hiking shoes. 5. NOTE: The insole is made with firm PU material. If your shoe has a stiff midsole, slight friction or noise may occur, which is normal. You may experience some foot pressure during the first 3–7 days of use. It is recommended to start wearing them for 2–3 hours per day and gradually increase the duration.
