The first coupling section is set at one side of the accommodation space and the second coupling section is set at an opposite side of the accommodation space. As such, when a wearer puts her foot in the shoe body, the elastic connector can be fit over a heel of the wearer so that the shoe body is securely attached to the foot of the wearer without undesired separation, whereby an effect of preventing separation of the shoe body can be achieved when the wearer is walking. ## Claims ### Claim 1 An elastic structure, comprising: an elastic connector; a first coupling section, which is mounted to an end of the elastic connector; and a second coupling section, which is set opposite to the first coupling section and is mounted to another end of the elastic connector. ### Claim 2 (depends on 1) The elastic structure as claimed in claim 1, wherein the elastic connector further comprises a first elastic connection section and a second elastic connection section, the first elastic connection section having an end coupled to an end of the second elastic connection section. ### Claim 3 (depends on 2) The elastic structure as claimed in claim 2, wherein the first elastic connection section comprises a first elastic segment and a first sleeve, the first elastic segment having an end received in and fixed to the first sleeve, the second elastic connection section comprising a second elastic segment and a second sleeve, the second elastic segment having an end received in and fixed to the second sleeve, the first elastic segment having an opposite end connected to an opposite end of the second elastic segment. ### Claim 4 (depends on 3) The elastic structure as claimed in claim 3, wherein the opposite end of the first elastic segment and the opposite end of the second elastic segment are respectively provided with counterpart components of a Velcro strip. ### Claim 5 (depends on 3) The elastic structure as claimed in claim 3, wherein the opposite end of the first elastic segment and the opposite end of the second elastic segment are respectively provided with counterpart components of a fastener. ### Claim 6 (depends on 3) The elastic structure as claimed in claim 3, wherein the opposite end of the first elastic segment and the opposite end of the second elastic segment are respectively provided with counterpart components of a snap-fitting coupling. ### Claim 7 (depends on 3) The elastic structure as claimed in claim 3, wherein the first sleeve and the second sleeve are each provided with an opening. ### Claim 8 A shoe, comprising: a shoe body, which forms an accommodation space; and an elastic structure, which comprises an elastic connector; a first coupling section that is mounted to an end of the elastic connector; and a second coupling section that is set opposite to the first coupling section and is mounted to an opposite end of the elastic connector, the first coupling section being set at one side of the accommodation space, the second coupling section being set at an opposite side of the accommodation space. ### Claim 9 (depends on 8) The shoe as claimed in claim 8, wherein the elastic connector further comprises a first elastic connection section and a second elastic connection section, the first elastic connection section being set at one side of the accommodation space of the shoe body, the second elastic connection section being set at an opposite side of the accommodation space of the shoe body, the first elastic connection section having an end connected to an end of the second elastic connection section. ### Claim 10 (depends on 9) The shoe as claimed in claim 9, wherein the first elastic connection section comprises a first elastic segment and a first sleeve, the first elastic segment having an end received in and fixed to the first sleeve, the second elastic connection section comprising a second elastic segment and a second sleeve, the second elastic segment having an end received in and fixed to the second sleeve, the first sleeve having one side coupled to one side of the accommodation space of the shoe body, the second sleeve having one side coupled to an opposite side of the accommodation space of the shoe body, the first elastic segment having an opposite end connected to an opposite end of the second elastic segment. ### Claim 11 (depends on 9) The shoe as claimed in claim 9, wherein the opposite end of the first elastic segment and the opposite end of the second elastic segment respectively forming counterparts of a Velcro strip. ### Claim 12 (depends on 9) The shoe as claimed in claim 9, wherein the opposite end of the first elastic segment and the opposite end of the second elastic segment respectively forming counterparts of a fastener. ### Claim 13 (depends on 9) The shoe as claimed in claim 9, wherein the opposite end of the first elastic segment and the opposite end of the second elastic segment respectively forming counterparts a snap-fitting coupling. ### Claim 14 (depends on 9) The shoe as claimed in claim 9, wherein the first sleeve and the second sleeve are each provided with an opening.
