Abstract: A shock absorber for a sports floor assembly. The shock absorber has a base portion and a nodule portion. The base portion is formed of an elastomeric material. The nodule portion extends a distance from one side of the base portion and has a first layer formed of an elastomeric material with a durometer Shore hardness substantially equal to the durometer Shore hardness of the base portion. The nodule portion has a second layer formed of an elastomeric material having a durometer Shore hardness less than the durometer Shore hardness of the base portion and the first layer of the nodule portion.
