Abstract
A roller-skating boot has a wheel support turnably fitted to a front connecting portion of the sole thereof. Two front wheels are provided at two ends of the wheel support such that the user can be supported with increased stability by the side-by-side arranged front wheels and other wheels that are arranged in one line behind the front wheels. The wheel support has a protrusion sticking up to be movably confined in a guide trench of the front connecting portion so as to limit the change of orientation of the wheel support in relation to the sole to a certain range.
