Strong PP shell combined with high resilience EVA cushion has a high impact resistance performance to help against the high impact force in the soccer game. (NOTE: The shin guard DOES NOT cover the whole lower leg.) (Patent Pending) | ?Lengthen 1.4 inch Velcro Strap?: Two adjustable elastic Velcro straps fix the shin guard up and down. Dual adjustable hook and loop buckle add more stability at the same time, preventing the shin guards from falling off effectively. Velcro straps lengthened 1.4 inch to make the adjustable length range wider.
