[universal in-line skates]

Abstract

A pair universal in-line skating shoes is provided. The skates comprise a front base, a rear base, a shoe body, a number of wheel assemblies and two length-adjusting members. The length-adjusting members are replaceable. Two ends of the length-adjusting members are connected to the front base and the rear base respectively. When a user needs a pair of skates with a greater length, there is no need to purchase a new pair because the length of the old pair of skates can be increased through a replacement of the length-adjusting members. Optionally, an additional wheel extension plate having at least one hole for adding other wheel assemblies can be added to the front end of the front base.
