Chinese patent CN03231189.3 discloses "a kind of size-adjustable skates", which includes a toe cap and a shoe body part. The shoe body part includes a sole and a heel part. It is connected to the front end of the sole for longitudinal movement, and a size adjustment device that can adjust and lock the longitudinal relative position of the toe cap and the sole is installed between the toe cap and the sole. The size adjustment device includes a positioning groove, a positioning buckle and a return pressure spring. A row of zigzag-like locking teeth is provided on the outer wall of the positioning groove, and a buckle that can be aligned with the locking teeth is provided at the front end of the positioning buckle. In order to prevent the toe cap from detaching from the shoe body in the longitudinal direction, a positioning bar needs to be set in the positioning groove, and a slot hole and a corresponding bump that can be embedded in the positioning groove need to be opened at the bottom of the toe cap, so as to prevent the toe cap from loosening left and right , it is also necessary to set a limit groove and a limit protrusion on the sole and the toe cap. This design makes the structure of the sole and the toe cap very complicated, and the parts for adjusting the length are located at the front end of the shoe. Easier to damage by impact.

The traditional roller skates with the adjusting device located at the heel rely on the sliding between the shoe shell and the base to achieve the adjustment, which causes the center of gravity of the heel to change with the adjustment, causing the center of gravity of the heel to deviate from the optimal position.
