1. Materials

　　Tri-Laminate Diabetic Insoles are constructed from a high-quality combination of materials designed to provide patients with superior comfort and support.

　　Top material: Made of soft and breathable microfiber fabric, which can effectively absorb sweat and keep feet dry. Its thickness is about 2mm and its softness reaches level, providing a light touch to the feet.

　　Middle layer material: Made of highly elastic memory foam material with a thickness of 4mm, it can adapt to the shape and pressure distribution of the foot to provide personalized support. Its slow rebound rate is controlled within, ensuring that it can maintain good support effect after long-term use.

　　Bottom material: Made of hard EVA material, with a thickness of about 3mm and excellent pressure resistance and wear resistance. Its compressive strength reaches, which can effectively disperse the impact force during walking and protect the feet from damage.

　　2. Manufacturing process

　　Three-layer diabetic insoles use advanced hot-pressing molding technology to ensure that each layer of materials is tightly combined to form an integrated structure. By precisely controlling temperature and pressure, each layer of material fuses with each other during the heat pressing process to form a strong and durable insole.

　　3. Production process

　　Material preparation: According to the design requirements, prepare the required three layers of materials and perform pre-processing, such as cleaning, drying, etc.

　　Cutting and positioning: According to the size and shape of the insole, use precise cutting equipment to cut each layer of material into the corresponding shape, and use positioning marks to ensure accurate alignment between the layers.

　　Hot press molding: Place the cut layers of materials in a hot press mold, and perform hot press molding by controlling the temperature and pressure. During this process, the layers of materials fuse with each other under the action of heat and pressure to form a tight bond.

　　Cooling and trimming: After the insole has cooled, perform necessary trimming and polishing to ensure a flat surface and smooth edges.

　　Quality inspection: Strict quality inspection of finished products, including measurement of size, thickness, hardness and other parameters, to ensure compliance with design requirements.

　　4. Product characteristics

　　Personalized support: The mid-layer memory foam material can adapt according to the shape and pressure distribution of the foot, providing personalized support and comfort.

　　Excellent cushioning performance: The underlying EVA material has excellent pressure resistance and wear resistance, which can effectively absorb and disperse the impact force during walking, reducing foot fatigue and pain.

　　Breathable and Dry: The top layer of microfiber fabric has good breathability, which can keep feet dry and reduce bacterial growth.

　　Lightweight and durable: The overall design is light and thin, making it easy to carry and wear; at the same time, it is made of high-quality materials and has a long service life.

　　5. Product efficacy

　　Tri-laminated diabetic insoles are specially designed for diabetics and have the following significant benefits:

　　Reduce foot pain: Effectively reduce foot pain and discomfort caused by standing or walking for long periods of time by providing personalized support and cushioning.

　　Improve foot blood circulation: Excellent support and cushioning help reduce foot pressure and friction, thereby improving foot blood circulation.

　　Prevent foot ulcers and infections: Reduce pressure and friction on the feet, reduce the risk of ulcers and infections, and protect the patient’s foot health.

　　To sum up, the three-layer diabetic insole provides a comfortable and effective foot protection solution for diabetic patients with its high-quality materials, advanced manufacturing technology and excellent product characteristics. During use, patients should keep the insoles clean and dry, and replace them regularly to ensure optimal use.
