NBNQC’s Crucial Role in Footwear Quality Assurance in China

NBNQC plays a vital role in the  industry, specializing in the examination of various types of shoes, including sports shoes, leather shoes, vulcanized shoes, and more. In this article, we will primarily focus on the quality requirements for running shoes to prevent sports-related injuries. Furthermore, we will provide insights into our approach to conducting quality inspections for running shoes.

Section 1: Quality Requirements for Running Shoes

Running shoes are specifically designed to provide comfort, support, and protection during physical activities such as jogging, running, and other forms of exercise. To ensure the quality of running shoes and prevent sports injuries, the following aspects should be considered:

1. Cushioning and Shock Absorption: Running shoes must feature adequate cushioning to absorb the impact generated during each footstrike. High-quality midsole materials, such as ethylene-vinyl acetate (EVA) or polyurethane foam, should be used to provide excellent shock absorption.

2. Stability and Support: The shoe’s design should offer stability to prevent excessive foot and ankle rolling, reducing the risk of sprains or other injuries. Features like arch support and a well-structured heel counter are essential in maintaining proper foot alignment during running.

3. Breathability and Moisture Management: Running shoes should have sufficient breathability to allow airflow and moisture-wicking properties to keep the feet dry. Mesh and breathable upper materials help regulate temperature and prevent excessive sweating, reducing the likelihood of blisters and discomfort.

4. Traction and Outsole Durability: A durable outsole with good traction is crucial for providing grip and preventing slips or falls during running on various surfaces. High-quality rubber compounds, with well-designed tread patterns, enhance both traction and durability.

5. Flexibility and Toe Box Room: Running shoes should offer flexibility to accommodate the natural foot movement while providing enough room in the toe box for comfortable toe splay. A restrictive toe box can lead to discomfort, blisters, and other foot problems.

Section 2: Quality Inspection Process for Running Shoes

To ensure that running shoes meet the necessary quality requirements, NBNQC employs a comprehensive inspection process. Here is an overview of the key steps involved:

1. Visual Inspection: Our inspectors thoroughly examine the overall appearance of the running shoes, checking for any defects in stitching, gluing, or material irregularities. They also verify if the shoe design aligns with the provided specifications.

2. Material and Component Evaluation: We assess the quality and suitability of the materials used in the upper, midsole, outsole, laces, and other components. This includes testing the strength, flexibility, and resistance to wear and tear.

3. Comfort and Fit Testing: Our inspectors assess the comfort and fit of the running shoes by wearing them and conducting various movements, such as walking, running, and lateral movements. This helps identify any discomfort, improper fit, or performance issues.

4. Performance and Safety Testing: We conduct tests to evaluate the shoe’s performance and safety features. This includes measuring cushioning and shock absorption, examining traction and slip resistance, and verifying stability and support features.

5. Durability Testing: To assess the durability of running shoes, we conduct simulated wear tests, subjecting the shoes to rigorous conditions like flexing, abrasion, and impact. This ensures that the shoes can withstand the demands of regular running activities.

Conclusion:

Running shoes play a critical role in preventing sports-related injuries, and ensuring their quality is paramount. NBNQC, as a prominent player in the Chinese footwear inspection sector, undertakes thorough quality assessments to guarantee that running shoes meet the necessary requirements. By adhering to stringent inspection processes, we contribute to the production of high-quality running shoes that prioritize comfort, support, durability, and overall safety for athletes and fitness enthusiasts alike.
