Silicone shin-guard bands are a thin hold around the pad when you do not want a full sleeve. They grip the sock and the guard so a moulded Shinplex shell stays put without wrapping the whole calf. Sizes follow roughly the same age bands as the ankle guards. They are not protection on their own.
Use them if straps feel bulky and tape feels wasteful. Pair with a custom-fit pad — silicone will not rescue a loose slip-in. Free UK shipping over £45.
