         2 . The roller skate of  claim 1 , wherein the slot extends at least partially in a longitudinal direction of at least one of the rail and the sole. 
     
     
         3 . The roller skate of  claim 1 , wherein the fastening device is arranged in a heel region of at least one of the rail and the sole. 
     
     
         4 . The roller skate of  claim 1 , wherein the fastening device is arranged in a foot ball region of at least one of the rail and the sole. 
     
     
         5 . The roller skate of  claim 1 , further comprising a cover unit arranged on a top side of the sole, the cover unit including an underside facing the sole and a receptacle located on the underside, wherein the fastening device includes two bearing parts disposed at opposite ends of the connecting bolt, and wherein one of the bearing parts is received within the receptacle. 
     
     
         6 . The roller skate of  claim 5 , wherein the fastening device includes a washer at least partially surrounding the second fastening opening, and wherein the washer is received within the receptacle. 
     
     
         7 . The roller skate of  claim 1 , wherein the sole includes a depression located on a top side of the sole, wherein the second fastening opening extends through the depression, wherein the fastening device includes two bearing parts disposed at opposite ends of the connecting bolt, and wherein one of the bearing parts is received within the depression. 
     
     
         8 . The roller skate of  claim 7 , further comprising a cover positioned over the depression to cover the depression. 
     
     
         9 . The roller skate of  claim 7 , wherein the fastening device includes a washer disposed within the depression such that the washer at least partially surrounds the second fastening opening. 
     
     
         10 . The roller skate of  claim 1 , wherein the fastening device is configured as a screw connection 
     
     
         11 . The roller skate of  claim 1 , wherein the fastening device is configured as a quick-action clamping device. 
     
     
         12 . The roller skate of  claim 1 , wherein the fastening device is a first fastening device, wherein the roller skate further comprises a second fastening device, and wherein one of the first and second fastening devices is arranged in a heel region of at least one of the shoe and the rail, and the other of the first and second fastening devices is arranged in a foot ball region of at least one of the shoe and the rail. 
     
     
         13 . The roller skate of  claim 12 , wherein the first and second fastening devices are spaced from one another in a longitudinal direction of at least one of the shoe and the rail. 
     
     
         14 . The roller skate of  claim 1 , wherein the rail has a length between about 150 millimeters and about 320 millimeters. 
     
     
         15 . The roller skate of  claim 1 , further comprising
 first and second axle receptacles;   first and second axles arranged on the respective first and second axle receptacles; and   a pair of rollers supported on each of the first and second axles.   
     
     
         16 . The roller skate of  claim 15 , wherein the respective pairs of rollers are spaced from one another by a distance between about 70 millimeters and about 220 millimeters. 
     
     
         17 . The roller skate of  claim 15 , wherein each of the rollers has a diameter between about 40 millimeters and about 80 millimeters. 
     
     
         18 . The roller skate of  claim 15 , wherein the rail includes first and second fastening means on which the respective first and second axle receptacles are arranged, and wherein the first and second fastening means each form an included angle between about 10 degrees and about 45 degrees with a support surface of the rail. 
     
     
         19 . The roller skate of  claim 1 , wherein the rail is formed from at least one of aluminum, magnesium, titanium, steel, plastic, fiber-reinforced plastic, carbon, fiberglass, and a material mixture of carbon and fiberglass. 
     
     
         20 . The roller skate of  claim 1 , wherein the sole is formed from at least one of leather, synthetic leather, rubber, plastic, a fiber-reinforced plastic, carbon, fiberglass, and a material mixture of carbon and fiberglass.
