Find Your Perfect Fit (Special Attention to XS): XS (calf circumference 5.5"–8.0", age ≤5) is specially designed for toddlers—please measure your child’s calf carefully and select XS only if the measurement matches. S (8.0"–9.8", age ≤9) fits young children. M (9.8"–11.8"), L (11.8"–14.2"), XL (14.2"–16.9"), and XXL (16.9"–20.9") ensure a great fit for youth, women, and men. Always measure calf circumference 2" (5 cm) below the kneecap and check our size chart for the best fit. High-Quality Comfort and Durability: Experience unparalleled comfort and lasting durability with our shin guards, crafted from a premium blend of spandex and nylon. Designed for optimal breathability and elasticity, they adapt seamlessly to your movements. Ultra-lightweight and flexible, these guards are not bulky like traditional protective gear. They ensure exceptional comfort and freedom, making them the perfect choice for athletes who demand high performance without compromising on comfort. Enhanced Protection with Advanced Design: Our shin guards feature a state-of-the-art honeycomb design for superior impact absorption and force dispersion, ensuring your shins are protected during intense play. The honeycomb padding molds perfectly to your shins, offering maximum flexibility and protection. Built-in anti-slip silicone strips keep the guards in place during dynamic activities, while flatlock seams offer a smooth, chafe-free fit that remains secure throughout your activities. Versatile Use for All Sports: Ideal for any sport involving rigorous leg activity—soccer, baseball, basketball, rugby, tennis, boxing, kickboxing, MTB, and more—these shin guards are also great for running, hiking, cycling, and weightlifting. They provide essential shinbone protection and professional-grade compression to support and warm calf muscles, reduce fatigue, and stabilize muscles, making them perfect for both high-stakes competitions and endurance challenges. Care Instructions: Extend the life and maintain the quality of your shin guards with these care tips. Hand wash with mild detergent, soak for ten minutes, and rinse thoroughly. Hang to dry without wringing. Avoid machine washing, direct sunlight, bleaching, and ironing, as these can damage the guards and reduce their effectiveness. Proper care preserves their shape and elasticity, ensuring continued optimal support and protection. HiRui shin guards offer incredible support while providing full shin, lateral, and medial protection. The hex pad design is flexible enough for your movements and provides outstanding protection, building up your confidence. Compression increases blood flow, keeps your muscles warm, and reduces fatigue and cramping. The guards conform to your calf and provide maximum protection. They are ideal for soccer players, designed to minimize the risk of injury especially during strenuous activities.
