Abstract: A cross-training flutter-kick boot system includes the use of a weighted elongate base having the general geometry of the bottom of the human foot. The base including an elevated central platform located opposite to an arch of the foot. The base also includes two pairs of hollow cylindrical elements, one element of each pair secured at a toe end of the weighted base and the other pair secured at a heel end of the base. A position control assembly (PCA) is securable upon the weighted base and includes respective front and rear hollow cylindrical elements which are securable within respective front and rear pairs of hollow elements by a platform connecting the front and rear I elements. The PCA, when secured to the weighted base, permits a bar having a channel to receive a second bar.
