Example one

Referring to fig. 1-4, the structure and method of use of the growing telescopic shoe will be described in detail. The growth telescopic shoe 100 of the present embodiment is composed of a resilient upper 101 and a telescopic sole 102, wherein the resilient upper 101 is made of high-elastic EVA, elastic mesh material, etc., and when the sole 102 is telescopic, the upper 101 can flexibly extend following the telescopic amount of the sole 102.

The telescopic sole is the main technical area of the utility model. The sole 102 includes a sole portion 103, an expansion member 105, and a heel portion 104, the sole portion 103 and the heel portion 104 being connected by the expansion member 105. The telescopic member 105 comprises a first telescopic part 106, a second telescopic part 107 and a fixed bolt 110, and when the telescopic amount of the telescopic member 105 is adjusted, the first telescopic part 106 slides in the second telescopic part 107; the first telescopic part 106 is provided with a plurality of fixing teeth 114 which are in limit fit with the fixing bolts 110, and the second telescopic part 107 is provided with through holes 120 through which the fixing bolts 110 pass.

Further, in order to better fix the expansion piece 105 to the sole 102, a first groove portion 108 and a second groove portion 109 are provided in the sole portion 103 and the heel portion 104, respectively. Preferably, the first flexible portion 106 is fixed to the first recess portion 108 by, but not limited to, gluing, and the second flexible portion 107 is fixed to the second recess portion 109 by, but not limited to, gluing. In order to improve the user's feeling when wearing, the first and second stretchable parts 106 and 107 are covered with a fabric buffer layer after being adhered in the recessed parts, so that the stretchable member 105 is not exposed to the outside, and the user's sole does not feel uncomfortable by directly touching the stretchable member 105.

The present embodiment does not limit the recess portion to which the first telescopic portion 106 and the second telescopic portion 107 are fixed, and theoretically, the first telescopic portion 106 and the second telescopic portion 107 can be fixed in any of the two recess portions to achieve the technical effect of freely extending and retracting, but the position of the fixing bolt 110 needs to be matched with the position change of the first telescopic portion 106. Since the heel portion has a large thickness and the fixing pin 110 is preferably provided, it is more practical to fix the first expansion portion 106 and the second expansion portion 107 to the first groove portion 108 and the second groove portion 109.

Further, although the fixing bolt 110 (latch) itself can function as a detent to stop the length of the telescopic member 105 at a proper position, the user cannot intuitively feel the adjusted length of the telescopic member 105, i.e., the user does not know whether the telescopic amount of the telescopic member 105 is proper or not. In order to solve the above technical problem, in the present embodiment, it is more preferable that a gear adjustment catch 115 is provided on the first telescopic part 106, and a chuck 116 engaged with the gear adjustment catch 115 is provided on the second telescopic part 107.
