FUNCTIONAL FOOTWEAR
The present invention relates to a functional footwear which comprises an insole having a toe-seating portion, whose height is higher than that of the remaining portion thereof other than the toe-seating portion, for allowing a user's toe to be seated thereon. The toe-seating portion of the insole of the functional footwear is formed higher than the remaining portion of the insole other than the toe-seating portion, so that toes of a walker are placed higher than the other portions of the sole of the feet of the walker, thereby obtaining an effect of the backward walking even when the walker walks forwardly.
The present invention relates to a functional footwear, in more particular, to a functional footwear which comprises an insole having a toe-seating portion, whose height is higher than that of the remaining portion thereof other than the toe-seating portion, for allowing a user's toe to be seated thereon.
BACKGROUND ARTAs an interest in human health has been increased along with a gradual improvement in the social life and economical development, a simple exercise easily performed in a daily life has been settled. In particular, a safe walking has been generalized which is available for everyone regardless of age or sex and is enjoyable without any special equipment or cost.
In such walking, forward walking as well as backward walking is popular. The backward walking has several advantages in that it stimulates muscles which are not normally used in the forward walking, and also has less impact than the forward walking when a user's feet come into contact with the ground. Further, when the user walks backwardly at the same velocity as that in forward walking, the backward walking has a greater calorie consumption than that in the forward walking.
Nevertheless, since a person who walks backwardly has a danger of collision or stumbling against another walker, the backward walking is relatively not widely performed as compared to the forward walking.
Since a footwear is indispensable for such walking exercise and absolutely influences an exercise effect, various kinds of footwear have been currently suggested in order to increase an exercise effect at the time of walking.
Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a functional footwear which comprises an insole having a toe-seating portion formed at the front portion thereof for allowing a user's toe to be seated thereon so as to remove dangers occurring when backward walking, so that an effect of the backward walking can be obtained while forward walking.
Technical SolutionIn order to accomplish the above objects, according to the present invention, there is provided a functional footwear comprising an upper, an outsole, and an insole, the insole being adapted to be replaceably used as needed, wherein the insole comprises a toe-seating portion formed at the front portion thereof for placing a user's toe thereon, the height of the toe-seating portion being higher than that of the remaining portion thereof other than the toe-seating portion, and the inner end of the toe-seating portion being concavely curved so as to allow a user's toes to be comfortably seated thereon.
Preferably, the toe-seating portion of the insole has a height of 0.5 to 1 cm.
Preferably, the height of the front portion of the upper is set in proportional to that of the toe-seating portion.
Further objects and advantages of the invention can be more fully understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
Hereinafter, a preferred embodiment of the invention will be explained in detail with reference to the appended drawings.
As shown in
The insole 20 according to the present invention has a toe-seating portion 22 formed on the front portion thereof for allowing a user's toe to be seated thereon, whose height(h) is higher than that of the remaining portion other than the toe-seating portion thereof. At this time, the remaining portion of the insole has an identical configuration to that of a typical insole 20.
Typically, when backward walking on shoe, the toe of a walker is elevated and movement of muscles is different from the movement of muscles when forward walking.
When backward walking on the functional footwear 10 of the present invention, the toe of a walker is maintained in a state where it is elevated even when forward walking. Thus, an exercise effect of the backward waling can be obtained even when forward walking.
The height(h) of the toe-seating portion 22 is preferably formed to have a height of 0.5 to 1 cm. When wearing the functional footwear 10 having the toe-seating portion 22 with a height smaller than 0.5 cm, a walker hardly has a sufficient exercise effect obtained when the toe of the walker is sufficiently elevated. Further, when wearing the functional footwear 10 having the toe-seating portion 22 with a height higher than 1 cm, the toe of the walker is overstrained. Therefore, the height of 0.5 to 1 cm is most suitable for the toe-seating portion 22.
Besides, the inner end of the toe-seating portion 22 is concavely curved so as to allow the toes of the walker to be comfortably seated thereon, because the toes of the human body is shaped to be concavely curved.
Further, as shown in
In addition, as shown in
In accordance with the functional footwear constructed as described above, since the toes of a walker is relatively highly placed unlikely the other typical footwear, muscles which are not normally used in a daily life are used to promote uniform development of muscles of the human body, thereby strengthening muscles of the femoral region and the waist of the human body.
If a walker wishes an effect of the forward walking while wearing the insole 20 of the invention, the walker can replace the insole 20 of the invention with a typical insole of conventional invention. That is, these diverse effects can be achieved by one functional footwear of the invention.
INDUSTRIAL APPLICABILITYAs described above, according to the present invention, the toe-seating portion of the insole of the functional footwear is formed higher than the remaining portion of the insole other than the toe-seating portion, so that toes of a walker are placed higher than the other portions of the sole of the feet of the walker, thereby obtaining an effect of the backward walking even when the walker walks forwardly.
While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
