Abstract: An ice-skate having a high shoe upper part, in particular in the area of sport, requires an increased spatial requirement for the ankle in the event of a pronounced forwards inclined movement. Therefore, it is recommended to form the closure edges in the upper shaft region so as to protrude in a convex manner in the direction of the foot middle plane, in order to increase the size of the surface and to place forward the closure parts in order to change the pulling effect thereof. Furthermore, lining or padding can be provided in the region of the extensions.

Abstract: Single-track roller skate comprising at least three wheels which are disposed one behind the other and the rolling faces of which comprise in the cross-section substantially identical curvatures, wherein at least one front and/or rear wheel comprises at least in portions a comparatively different degree of elasticity than at least one central wheel. The rolling faces of the wheels comprise preferably a flat or slightly curved central portion and on both sides of this central portion in each case a more greatly curved running shoulder portion, wherein each running shoulder portion of the front and/or rear wheel comprises a comparatively higher degree of elasticity than that of the central wheel. In a convenient manner the tire body, forming the rolling face, of a front and/or rear wheel can be manufactured from a material having a lower Shore hardness than the wheel body of a central wheel.
