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 the 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 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), making them smaller than standard shin guards. This compact design ensures they stay securely in place during activity, eliminating concerns about slipping or falling off during play. Perfect match: These shin guards are compatible with football socks and standard athletic socks, providing a comfortable fit without discomfort or impact on performance. Ideal for protecting the lower legs during play, suitable for beginners and experienced athletes alike. Protective effect: Suitable for various physical activities such as football, running, tennis, racquetball, gym workouts, walking, and weightlifting. Helps protect against calf muscle injury, arthritis, tendinitis, sore muscles, and supports recovery after surgery.
