Slippers capable of quickly replacing linings

The slipper comprises a slipper body, an upper lining and a sole liner, the upper lining and the sole liner are correspondingly attached to the inner side of an upper of the slipper body and the surface of a sole, and tongue pieces arranged on the two sides of the upper lining are inserted into through grooves formed in the upper to be positioned; wherein backward clamping hooks are arranged on the edges of the two sides of the half sole of the sole liner, and the front edge of the arch-shaped upper of the slipper body can be hooked by the clamping hooks to form positioning. Front-and-back sliding is prevented, layering of the two can be effectively avoided, assembling is very easy and convenient, and inconvenience caused by reverse folding or barb insertion is reduced. The convex tongue and the tongue piece are inserted into the through groove of the upper in an overlapped manner to form tight fit, so that reliable fitting and positioning of the half sole area are achieved; and the heel part can be inserted
