The connecting member 3 comprises an inner blocking piece 31 and an outer blocking piece 32. The inner blocking piece 31 may be a flexible elongated sheet located in an inner side of the top portion of the front half of the outer shell 2. One end of the inner blocking piece 31 has a sleeve ring and a first position-constrained portion 312. The sleeve ring can be used as a first engaging portion 311. The first engaging portion 311 is connected to one end of the outer blocking piece 32 by passing upward through the first through hole 221. And the first position-constrained portion 312 is abutted upward against an inner side of the first flank portion 22. The other end of the inner blocking piece 31 has the other sleeve ring and a second position-constrained portion 314. Said the other sleeve ring can be used as a second engaging portion 313. The second engaging portion 313 is connected to the other end of the outer blocking piece 32 by passing upward through the second through hole 231. And the second position-constrained portion 314 is abutted upward against an inner side of the second flank portion 23. Thus, the two ends of the inner blocking piece 31 are unidirectionally positioned on the inner side of the top portion of the front half of the outer shell 2 respectively.
The outer blocking piece 32 comprises a first bending portion 33 and a second bending portion 34. The first bending portion 33 comprises a first buckle ring 331 and a first blocking rod 332. The first engaging portion 311 is sleeved on one end of the first buckle ring 331, so that the one end of the first buckle ring 331 is connected to the first engaging portion 311. The other end of the first buckle ring 331 is pivoted to one end of the first blocking rod 332. The second bending portion 34 comprises a second buckle ring 341 and a second blocking rod 342. The second engaging portion 313 is sleeved on one end of the second buckle ring 341, so that the one end of the second buckle ring 341 is connected to the second engaging portion 313. The other end of the second buckle ring 341 is pivoted to one end of the second blocking rod 342. The other end of the second blocking rod 342 is pivoted to the other end of the first blocking rod 332. Thus, through bending the inner blocking piece 31 and bending the outer blocking piece 32, the gap 24 between the first flank portion 22 and the second flank portion 23 is capable of being expanded or shrank, or the first flank portion 22 and the second flank portion 23 are capable of being expanded upward or shrank downward, so as to accommodate users with different foot widths and sizes, and effectively prevent the user's foot from dislocation during exercise.
