A foot height adjustment system is provided. The system can include a clamshell device comprising a first member having an exterior surface and a pivotably connected second member. The pivotable connection between the members can comprise at least one hinge. At least one foot can be disposed within an aperture disposed within the first member. The one foot can project a first distance from the exterior surface of the first member. An actuator, adapted to reversibly increase the projection of the at least one foot from the exterior surface of the first member to a second distance when the second member is pivoted about the at least one hinge, can link the second member and the at least one foot. The second distance can be greater than the first distance.
