Abstract: A spring board construction in one embodiment with a board member, first and second bindings, and first and second spring units coupled to the board member. The spring units can have resiliently deflectable upper and lower arcuate spring members joined in an opposing relationship. The spring units can be disposed generally parallel to one another and perpendicular to a longitudinal dimension of the board member. The first and second ends of the upper and lower arcuate spring members can be fixed together by being mutually enveloped in first and second encasements. The spring members can be crafted from a composite of plastic and fiberglass. Traction members can be fixed to mid-portions of the lower spring members.
