Abstract: Rolling or gliding sports equipment, such as an in-line roller skate, including such equipment or skate adapted to receive an independent boot. The equipment/skate according to the invention includes a frame, a base connected to the upper portion of the frame, and has an upper surface provided to support the walking sole of the boot, a rear quarter receiving the heel portion of the boot, an upper portion equipped with a comfort element surrounding the user's lower leg, a device for tightening the forefoot pressing the front portion of the boot against the upper surface of the base, a device for tightening the lower leg which tightens the upper portion against the user's lower leg, a device for maintaining the instep exerting a force on the instep portion of the boot and a reinforcement ensuring a continuous support from a lateral side to a medial side, and from the instep zone to the upper portion of the boot.

Abstract: 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.

The elongated member further includes, or has attached thereto between the wheel housings, a lower arc demarcated by an inwardly extending surface with respect to a line defined by the contact points of the two wheels 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.
