Definitions

• 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.
• 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.
• FIG. 1 is a cross-sectional view showing the use state of a conventional functional footwear.
• the functional footwear 100 of FIG. 1 has an identical insole 110 to a functional insole disclosed in Korean Utility Model Registration No.341399.
• the insole 110 is formed in a streamline shape as a whole, which comprises a front portion 112 for placing a user's toe thereon, a rear portion 114 for placing a user's heel thereon, and a curved portion for connecting the front and rear portions with each other therethough so as to allow an arch portion of the sole of a foot to abut thereagainst.
• the front and rear portions 112 and 114 have a predetermined thickness (tl, t2), respectively.
• the thickness tl of the front portion 112 is formed thicker than the thickness t2 of the rear portion 114.
• the insole 110 permits a user efficiently consume as much energy as required for making an ascent only by amount of exercise of usual walking level in a daily life when using the insole 110 inserted into a footwear 100.
• the thickness of the insole 110 becomes smaller as it goes from the front portion 112 to the rear portion 114, muscles of an ankle 120 and a front portion 130 of the calf of a user are readily fatigued when walking for a long time, as well as the knee joint of a user is overstrained, thereby having a reverse effect on the walking. Disclosure of Invention Technical Problem
• 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.
• 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.
• the toe-seating portion of the insole has a height of 0.5 to 1 cm.
• the height of the front portion of the upper is set in proportional to that of the toe-seating portion.
• FIG. 1 is a cross-sectional view showing the use state of a conventional functional footwear
• FIG. 2 is an exploded perspective view of a functional footwear according to a preferred embodiment of the present invention.
• FIG. 3 is a cross-sectional view taken along the line A-A of FIG. 2;
• FIG. 4 is a cross-sectional view showing the use state of a functional footwear according to a preferred embodiment of the present invention. [17]
• FIG. 1 is a cross-sectional view showing the use state of a conventional functional footwear
• FIG. 2 is an exploded perspective view of a functional footwear according to a preferred embodiment of the present invention
• FIG. 3 is a cross-sectional view taken along the line A-A of FIG. 2
• FIG. 4 is a cross-sectional view showing the use state of a functional footwear according to a preferred embodiment of the present invention.
• a functional footwear 10 of the present invention mainly comprises an outsole 14 for supporting the sole of a user's foot, an upper 12 for covering a user's foot, and an insole 20 inserted into the inside of the footwear 10.
• the insole 20 is separated and washed when being dirty, and separately mounted from the footwear so as to be replaceably used, whenever needed.
• the insole 20 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.
• the remaining portion of the insole has an identical configuration to that of a typical insole 20.
• the height(h)of the toe-seating portion 22 is preferably formed to have a height of
• a walker When wearing the functional footwear 10 having the toe-seating portion 22 with a height smaller than 0.5cm, 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 lcm, the toe of the walker is overstrained. Therefore, the height of 0.5 to lcm is most suitable for the toe-seating portion 22.
• 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.
• the toe-seating portion 22 is formed at the front portion of the insole 20 in such a manner that the height(h) of the toe- seating portion 22 is higher than the remaining portion of the insole 20 other than the toe-seating portion 22, the height(h) of the front portion of the upper 12 is preferably set in proportional to that of the toe-seating portion 22.
• the toe-seating portion 22 is perpendicularly extended upwardly from the top surface of the front portion of the insole 20, however, it can be perpendicularly extended downwardly from the underside surface of the front portion of the insole 20.
• 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.
• 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.
