Problems solved by technology

However, since the center of gravity of such sandals is set at the center in the front-rear direction, the center of gravity is the same as that of ordinary shoes and sandals when the wearer is wearing the sandals, making it difficult to obtain sufficient exercise effects.

Embodiment Construction

[0038] The following is based on Figure 1 to Figure 10 Embodiments embodying the present invention will be described in detail.

[0039] exist Figure 5 as well as Figure 6 One of the left and right pair of sandals 10 (sandal for the right foot) is shown in . Each sandal 10 is equipped with the main body 11, and the main body 11 has the skeleton part 19 made of hard resin. The skeleton part 19 is covered with the outer cover part 20 made of soft resin. The outsole portion 20 makes the sandals 10 feel good on the soles of the feet. Hard synthetic resins such as polyurethane resins, polyvinyl chloride resins, and polyester resins can be used as the hard resin. In addition, as the soft resin, in addition to ethylene-vinyl acetate copolymer resin (EVA), thermoplastic elastomers such as polyethylene-based elastomers and polystyrene-based elastomers can be used.

[0040] Such as figure 1 as well as figure 2 As shown, the main body 11 of the sandal 10 has: a main body fro...

Abstract

A sandal (10) comprises a main body (11). The main body (11) is configured from a main body forepart (12) which bears a forepart of a foot, including toes, and a main body aft part (13), which bears an aft part of a foot, including the heel. A weight balance of the sandal (10) is set such that the main body forepart (12) is lower than the main body aft part (13). A first curve face (12a), which is curved such that a middle part in the fore-aft direction protrudes further downward in the fore-aft direction than both ends, is formed upon the bottom face of the main body forepart (12), and a second curve face, which is curved such that a middle part in the left-right direction protrudes further downward in the left-right direction than both ends, is formed upon said bottom face. A depression part (15) which opens aft and toward both lateral parts is formed in the bottom part of the main body aft part (13). A thong (16) which is held between the toes is disposed upon the upper face of the main body forepart (12).

Description

technical field [0001] The present invention relates to sandals capable of realizing beautiful legs through exercise effects. Background technique [0002] In recent years, for example, as shown in Patent Document 1 and Patent Document 2, shoes such as sandals that pursue an exercise effect have been proposed. [0003] In the configurations described in Patent Document 1 and Patent Document 2, the bottom surface of the shoe is curved in an arcuate shape so that the middle portion in the front-rear direction protrudes downward from both ends in the front-rear direction. [0004] Patent Document 1: Japanese PCT Publication No. 2009-528879 [0005] Patent Document 2: Japanese Utility Model Registration No. 3168694 [0006] In the conventional sandals described in Patent Document 1 and Patent Document 2, the bottom surface thereof is curved as described above. However, since the center of gravity of such sandals is set at the center in the front-rear direction, the center of ...
