EvoShield's Batter's Leg Guard offers the highest level of protection for the shin, ankle, and foot. Lightweight, ultra thin, and breathable, this custom-molding leg guard will not slow you down. The custom-molding Shields form uniquely to each individual athlete's body, providing comfortable protection from foul balls and wild pitches. Simply remove the Shields from the foil bag to air activate the custom-molding process, leaving on the shin, ankle, and foot for 20-30 minutes until hardened. The batter's leg guard can be custom formed to either leg.
