[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A shoe with adjustable size comprises a sole 1 and an upper 2, wherein the sole 1 and the upper 2 are fixedly connected, a thread is provided at the heel of the upper 2, and an adjusting screw 3 is threadedly connected thereto, one end of the adjusting screw 3 is located outside the upper 2 and is fixedly connected to a knob 4, and one end of the adjusting screw 3 is located inside the upper 2 and is rotatably connected to a plastic heel 5.

[0026] The plastic heel 5 includes a hard plastic 501, a cavity 502 is provided inside the hard plastic 501, a soft covering layer 6 is fixedly connected to the surface of the hard plastic 501, the soft covering layer 6 includes a latex layer 601, the latex layer 601 is fixed to the surface of the hard plastic 501, an adhesive layer 602 is provided on the outer surface of the latex layer 601, and an antibacterial fabric layer 603 is bonded and fixed to the outer surface of the latex layer 601 through the adhesive layer 602.

[0027] like Figure 1 The heel of the upper 2 is a hard part, which is connected to the adjusting screw 3 through the thread it carries. The outer surface of the knob 4 has anti-slip patterns, which is convenient for manually rotating the knob 4 to drive the adjusting screw 3 to rotate. The other end of the adjusting screw 3 is rotatably connected to the plastic heel 5, so that when the adjusting screw 3 rotates, the plastic heel 5 can be driven to move inside the upper 2.

[0028] One end of the adjusting screw rod 3 is rotatably connected to the surface of the hard plastic 501 , and the surface of the hard plastic 501 is provided with a convex arc surface and a concave arc surface for fitting the heel.
