AllToze Knee Support 【Injury Prevention & Recovery】This knee support uses two adjustable support belts for fixation, enhancing the endurance of bones and muscles, and is useful for everyday knee support, protecting knees during sports, and preventing pain and injuries. The power taping belt compression design allows for easy walking without worrying about uneven surfaces, making it a great sports supporter. After an injury, it can be used as a medical support to reduce stress on the knee for joint pain, meniscus and ligament damage, and growing pains. • 【Anti-Slip & Allergy Prevention】Ordinary knee supports on the market may have anti-slip rubber that can cause allergies, but ATKOYO's knee support uses an ergonomic belt that wraps around the knee in opposite directions to prevent slippage, providing a more secure and stable feel, and eliminating the fear of numbness even during intense sports. • 【Excellent Breathability & Stretchability】Material: 68% nylon, 32% spandex. It uses breathable, sweat-absorbent, three-dimensional knitted fabric that allows for easy movement even during long periods of wear. It also has excellent elasticity, so there is no restriction. It is thin and does not easily get stuffy, reducing uncomfortable digging and minimizing itching and irritation to the skin, allowing for comfortable wear for extended periods even in hot weather. (Sweat-resistant and hand-washable.) ★★★"Important Notice"★★★ M (35-40cm), L (40-45cm), XL (45-50cm), XXL (50-55cm) Please contact us for size confirmation and stock availability before purchasing.
