Comfort material: The calf sleeves are made of high-quality plastic foam, which is both elastic and breathable to improve comfort and reduce sweating. The outer shell of the shin guards is made of strong plastic material with a layer of foam inside to reduce external impact forces, effectively protecting calf muscles, reducing sports injuries, and providing comprehensive protection for your tibia. Anti-slip design: The mini leg pads offer an ideal fit and contour for optimal comfort. The socks hold them securely in place, preventing movement or shifting during exercise, ensuring a tight, comfortable fit that minimizes sliding and friction between the shin pads and skin, enhancing performance without discomfort. Super-lightweight and compact: The mini shin pads measure 8 x 5 cm (3.14 x 1.96 in), smaller than standard shin guards. This design ensures they stay securely in place during play, eliminating concerns about slipping or falling off. Perfect match: These shin guards are compatible with football socks and standard athletic socks, providing comfort without restricting movement, making them suitable for beginners and experienced players alike. Protective effect: Ideal for various activities such as soccer, running, tennis, racquetball, gym workouts, walking, and weightlifting. Helps protect against calf muscle strain, arthritis, tendinitis, sore muscles, and supports recovery after injury.
