Coaches can teach players proper sliding techniques without worrying about season-ending injuries with these MacGregor® Shock-Absorbing Bases. As runners take off to steal second or third during the game, the bases absorb the brunt of the slide and cushion the force of a sliding player, helping to reduce the danger of running or stealing bases. Players' cleats won't damage the base as they forcefully step onto it to indicate they are safe thanks to the durable molded rubber construction, which resists rusting over time.
