Comfort material: The calf sleeves are made of high-quality plastic foam, which is elastic and breathable to enhance comfort and reduce sweating. The outer shell of the shin guards is constructed from durable plastic with a foam lining to help absorb external impact, providing effective protection for the tibia and reducing the risk of sports injuries. Anti-slip design: The mini leg pads feature an ergonomic shape for a secure and comfortable fit. Designed to stay in place when worn with socks, they minimize movement during activity, preventing slippage and skin friction for improved comfort and performance. Super lightweight and compact: Measuring 8 x 5 cm (3.14 x 1.96 inches), these mini shin pads are smaller than standard guards, offering a discreet and secure fit that stays in place during play. Perfect match: Compatible with football socks and standard athletic socks, these shin guards provide reliable lower leg protection without discomfort or restriction, making them suitable for both beginners and experienced players. Protective effect: Ideal for various physical activities including soccer, running, tennis, racquetball, gym workouts, walking, and weightlifting. Helps support the calf muscles and may assist during recovery from muscle soreness, tendonitis, arthritis, or post-injury conditions.
