A roller skate with an adjustable longitudinal dimension for adjusting the dimension of the shoe cap of the roller skate includes an anchor section under a two-piece shoe cap that has a first coupling section. An adjusting bolt is provided on the truck with a second coupling section and a sliding trough. The adjusting bolt may be moved horizontally through an elastic element. When the elastic element is depressed, the sliding trough is slid to the first coupling section of the anchor section to enable the shoe cap to be moved forwards and rearwards. When the elastic element is released, the two coupling sections are latched together to anchor the shoe cap. Thus the longitudinal dimension of the roller skate may be adjusted as desired.
