The new Synergy ST4 shin guards feature a wider knee cap providing great lateral support while allowing the knee to sit deeper into the pad. The ergonomic shin and adjustable liner comfortably cradle the lower leg providing better protection and comfort. This shin guard is fully ventilated to allow air flow through the plastic shell, and then through the inside liner. A tape line just below the knee provides a more efficient fit. A stretchable 2 strap design keeps the pads securely in place.
