Comfort material: The calf sleeves are made of high-quality 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 absorb external impact. This provides effective protection for the calf muscles, helps prevent sports injuries, and offers reliable coverage for the tibia. Anti-slip design: The mini leg pads feature an ergonomic shape for a secure fit. They stay firmly in place when worn with socks, minimizing movement during activity. This ensures a snug, comfortable feel while reducing slippage and skin friction, allowing for improved performance without irritation. Super lightweight and compact: These mini shin pads measure 8 x 5 cm (3.14 x 1.96 inches), making them smaller than standard guards. Their size ensures they remain securely positioned during play, eliminating concerns about shifting or falling off. Perfect match: These shin guards are designed to fit comfortably inside football socks and standard athletic socks. They do not cause discomfort or restrict movement, making them suitable for both beginners and experienced players. Protective effect: Ideal for various physical activities such as soccer, running, tennis, racquetball, gym workouts, walking, and weight training. Helps support the lower leg and may assist in managing muscle soreness, tendonitis, minor injuries, and post-exercise recovery.
