Patent literature 1. InPatent literature 1, a running shoe is disclosed in which a ring shaped portion is provided in a heel portion of a shoe to be engaged with a fixing belt, and the engaged fixing belt is wrapped around an ankle region of a user above a malleolus. With the art, the foot does not slip out from the shoe even in a case the heel portion is stepped on by a following runner in a packed group of runners. Thus, with the art, a case in which a runner is stepped on by the following runner at the heel portion and caused to be felled and injured is prevented to be occurred. - Patent Literature 1: Japanese Patent Application Publication No.
2003-009907 - Incidentally, in persons doing exercises such as running as daily activities, some eager to carry exercise shoes to business trip destinations or travel destinations and to do exercises there. However, the conventional exercise shoes of this kind are bulky and thus cause a problem to occupy a large space inside of a suitcase and so forth.
- This invention is intended to provide a footwear for exercise both providing a superior portability to that of a sports shoe and providing a comparative comfort in exercise with that of a sports shoe.
- In order to solve the above problem, this invention provides a footwear for exercise comprising: a covering member formed by sewing with elastic fabric in a conforming sock shape to a lower part of a malleolus of a user's foot; an insole member made of impact absorption material formed in a conforming sheet-like shape to the foot sole shape of the user, the insole member being placed between the covering member and the foot sole of the user in the covering member; a first rubber member attached on the outer surface of the covering member as to cover an entire bottom side portion of the covering member where the insole member is placed; a second rubber member attached on the outer surface of the covering member as to extend from a front end of the covering member to a nearby portion of a step-in opening of the covering member; and a third rubber member attached on the outer surface of the covering member as to extend from a rear end of the covering member to a nearby portion of a step-in opening of the covering member.
- In the footwear of this invention, a covering member formed by sewing with elastic fabric and rubber members attached on a part of the outer surface of the covering member are provided. The covering member is rolled as its front end being inserted into the step-in opening and then is packed in a substantially same size of a fist. In addition, the first rubber member is attached on the outer surface of the covering member as to cover an entire bottom side portion of the covering member where the insole member is placed. With the feature, a user can wear the footwear on the foot and can run in the forward direction with kicking the ground surface firmly. In addition, on the outer surface of the covering member, a second rubber member is attached as to extend from a front end of the covering member to a nearby portion of a step-in opening of the covering member, and a third rubber member is attached as to extend from a rear end of the covering member to a nearby portion of a step-in opening of the covering member. With the feature, in a running with the footwear worn on, the covering member is reduced to be twisted in the right and left and the foot is reduced to be popped out from the covering member. Accordingly, with this invention, a user can carry the footwear for exercise to a difficult destination to carry sports shoes such as business trip destinations, travel destinations and so forth, for example, and can do exercises there comfortably as if he wears a sports shoe on.

As a result, according to this embodiment, a user can carry thefootwears - Second, on the outer surfaces of the covering
member rubber members 18L-k and 18R-k are formed as to bended inwardly to conform to the rounds of the insteps of user's feet. In addition, the rear end portions of therubber members elastic bands rubber members elastic bands members rubber members 18L-k and 18R-k and by the inwardly bended rear end portions of therubber members rubber members members member 10L and the right foot is reduced to be popped out from the coveringmember 10R. - Third, because the
footwears members rubber members - Fourth, in this embodiment, in the
bottom portions 40L and 40R of the internal surfaces of the coveringmembers insole members 11L and 11R are placed, the indented portions are formed. Thus, with this embodiment, theinsole members 11L and 11R can be gripped with stronger forces. - Fifth, in this embodiment, the
insole members 11L and 11R are made of EVA. EVA is known as a material having a more flexible and thus gives softer feel than other resin materials used in the same purpose. Thus, this embodiment can provide a higher comfort in a running than a case in which the other resin material is used for theinsole members 11L and 11R. - Sixth, in this embodiment, the bottom surfaces 52L and 52R of the
insole members 11L and 11R are formed in flat surfaces, and thetop surfaces 51L and 52R of theinsole members 11L and 11R are formed in the patterned indented surfaces at a beneath portion of a heel bone, at a beneath portion of a metatarsal bones and at beneath portion of a toe bones of the user's feet. Thus, theinsole member 11L in the coveringmember 10L and the insole member 11R in the coveringmember 10R can be exchangeable each other with each of them turned the top surface and the bottom surface over. Some users of thefootwears insole members 11L and 11R for the left foot and the right foot, some users may prefer the conformed dimpled shapes in exercise to the foot soles at the beneath portions of the left foot and the right foot of theinsole member 11L and 11R. In addition, some users may prefer the flat surfaces in a exercising case with jumps such as running for the left foot and the right foot, and may prefer the conformed dimpled shapes in other exercising case without jumps such as gymnastic exercises to the foot soles at the beneath portions of the left foot and the right foot. With this embodiment, users can select the fitting feels of theinsole members - Seventh, in this embodiment, the
grooves 31L and 31R are formed from the front end to the rear end of therubber members 15L and 15R. Thus, this embodiment can improve the straight-running stability when users wear thefootwears - Eighth, in this embodiment, at the step-in
openings 13L and 13R of the coveringmembers elastic bands members - The above description is an embodiment of this invention, and the embodiment may be modified as follows.
- (1) In the above embodiment, the project portions S formed on the
bottom section 40L is formed in perfect circle shapes. Instead of the structure, the project portions S may be replaced to project portions shaped in stripes. - (2) In the above embodiment, the
rubber members 18L-k are provided by three. Instead of the structure, therubber members 18L-k may be provided by one or two, or provided by five or more. - (3) In the above embodiment, in the bottom surface of the
rubber member 15L, both of thelongitudinal groove 31L and thetransverse grooves 32L-i (i = 1 to 6) and 33L-i (i = 1 to 6) are provided. Instead of the structure, only thelongitudinal groove 31L may be provided in the bottom surface of therubber member 15L. - 1 ... footwear, 10 ... covering member, 11 ... insole member, 13 ... step-in opening, 14 ... elastic band, 15, 16, 17, 18 ... rubber member, 31 ... longitudinal groove, 32, 33 ... transverse groove, 40 ... bottom portion, 51 ... top surface, 52 ... bottom surface, 53, 54, 55 ... dimple portions
