Abstract: A hard-shell boot comprises a boot liner and an outer shell having an accommodation space for accommodating and positioning the boot liner. Two sides of a top portion of the outer shell respectively have a first flank portion vertically penetrated by a first-through-hole and a second flank portion vertically penetrated by a second-through-hole. A connecting member comprises an inner-blocking-piece located in an inner side of the top portion of the outer shell and an outer-blocking-piece. One end and the other end of the inner-blocking-piece respectively have a first-engaging-portion connected to one end of the outer-blocking-piece by passing upward through the first-through-hole and a second-engaging-portion connected to the other end of the outer-blocking-piece by passing upward through the second-through-hole. Thus, the width and size of the hard-shell boot can be adjusted simultaneously to facilitate the use of users with different foot widths and sizes.

Abstract: A hard-shell boot comprises a boot-liner and an outer-shell having an accommodation-space for accommodating and positioning the boot-liner, the boot-liner has a sole which comprises a first-elastic-sheet and a rear-bottom-sheet on the same level, the rear-bottom-sheet is jointed to a rear side of the first-elastic-sheet; an outer periphery of the sole is extended upward to form an upright-portion which comprises a second-elastic-sheet and a rear-upright-sheet, two ends of a rear side of the second-elastic-sheet are jointed to two ends of a front side of the rear-upright-sheet respectively, an outer periphery of a top portion of the upright-portion is extended upward to form a sleeve-portion, a front end of the sleeve-portion has a third-elastic-sheet; thus, it is capable of being adjusted according to the width and size of the user's foot simultaneously, so as to facilitate the use of users with different foot lengths and sizes.
