A frame for a skate, and a skate having a frame, the frame including a lower longitudinally elongated member for supporting the wheels of the skate, a housing at opposite ends of the elongated member, each housing demarcated by a pair of lateral walls between which is assembled a respective wheel mounted on an axle. The elongated member further includes, or has attached thereto between the wheel housings, a lower arc demarcated by a surface facing a line defined by the contact points of the two wheels while supported on a planar surface. The arc extends over a length equal to or greater than a third of the distance between the two wheel axles at each of the ends of the elongated member of the frame.
