CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims benefit under 35 U.S.C. .sctn. 119 from Korean Patent Application No. 2004-65399, filed on Aug. 19, 2004, the entire content of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to an apparatus for tightening a top of a foot in a leisure sports boot fixing a heel to a sole, and more particularly to, an apparatus for tightening a top of a foot which can tighten a tightening band for fixing an upper portion of an ankle in a boot to make the foot and the boot adhered to each other in order to prevent edge control failure by foot movement in the boot in a snowboard controlling a speed and a direction by movement of gravity center and up/down right/left motions of feet. [0004] 2. Description of the Related Art [0005] Snowboarding has gained great popularity every year and has been widely distributed as leisure sports. As popularity of snowboarding gests grown as sports, there are increasing demands on precise equipments for high level operations. [0006] FIG. 1 is a perspective view illustrating a boot bound on a snowboard. A binder 30 is used to connect or disconnect the boot 20 to/from the snowboard 10. When the user moves on a skiing ground, the user disconnects the boots 20 from the snowboard 10 and carries them. When the user wants to snowboard, he/she mounts the boots 20 on the snowboard 10 by using the binders 30. [0007] Referring to FIG. 1, the binder 30 consisting of a pair of bands fixed on the board 10 for tightening the boots 20 includes a frame 32 fixed on the board 10, a heel fixing means 34 connected to the frame 32 for covering a heel of the boot 20, and a plurality of bands 36 and 38 coupled to the frame 32 and the heel fixing means 34 to be extended, connected or disconnected. [0008] That is, the boot 20 is put on the frame 32 with its heel adhered to the heel fixing means 34, and the plurality of bands 36 and 38 are expanded or contracted through a detachable hole 40, thereby connecting the boot 20 to the board 10. [0009] To enjoy snowboarding, the user wears liners 50 for ankle protection before wearing the boots 20. After wearing the liners 50, the user tightens bands (not shown) of the liners 50 to make the liners 50 and the feet adhered to each other. [0010] In a state where the user wears the liners 50 for protecting the upper portions of the ankles to efficiently enjoy snowboarding, the user prevents movement of the feet and the liners 50 by tightening the bands (not shown), wears the boots 20 over the liners 50, tightens tightening bands 60 to make the feet, the liners 50 and the boots 20 adhered to each other, and fixes the boots 20 on the board 10 by using the binders 30. As a result, the feet, the liners 50, the binders 30, the boots 20 and the board 10 are adhered to each other, so that the user can enjoy snowboarding. [0011] However, when snowboarding on snow, the user takes various postures on the snowboard 10 to change a direction or increase a speed. Especially, in order to increase the speed with the least resistance, the user descends in a state where the snowboard is inclined at a predetermined angle to the front or rear portion. Here, loads are concentrated on the ankles or tiptoes. [0012] When the user inclines one side edge of the snowboard 10 by inclining himself/herself to the rear portion for rear or heel side rotations, supporting means can be installed near calves to reduce muscular loads. Conversely, when the user inclines the other side edge of the snowboard 10 for front or tiptoe side rotations, as shown in FIG. 2b, the heels are separated from the bottoms of the boots 20, the snowboard 10 is not inclined to the front portion as the user expected, and loads are seriously applied to muscles of the calves. [0013] Especially, if the heels are not adhered to the bottoms of the boots 20, it is very disadvantageous in freestyle postures requiring strong force of the ankles and feet such as rapid rotations or high difficulty performance. That is, the user cannot show various and difficult techniques. [0014] In addition, when the user mostly uses muscles of the ankles or calves, he/she may be injured. It would cause a big problem in dangerous situations. [0015] The aforementioned problems are also generated in golf, mountain climbing, or inline skating. [0016] In the case of golf, the player fixes both feet on the ground and moves only the waist and shoulders in swing. Therefore, if the feet move or are separated from the ground, the user cannot take a stable posture. Generally, when a beginner concentrates on the tiptoes in swing, the heels of the feet are separated from golf boots, so that he/she cannot take a stable posture. [0017] In the case of mountain climbing boots, even if the user tightens tightening bands, heels are separated from the boots on a slope, and thus loads are applied to tops and ankles of the feet. SUMMARY OF THE INVENTION [0018] The present invention is achieved to solve the above problems. An object of the present invention is to provide an apparatus for tightening a top of a foot in a leisure sports boot fixing a heel to a sole which allows the user to take various postures, reduces loads on muscles of an ankle and a calf by making the foot and the boot adhered to each other even when the user is inclined to the front, and precisely transfers wanted techniques of the user to tiptoes. [0019] In order to achieve the above-described object of the invention, an apparatus for tightening a top of a foot in a leisure sports boot having a sole forming the bottom of the boot; a boot upper rim forming the top end of the boot and having a U-shaped front surface; a boot upper being extended between the sole and the boot upper rim, and consisting of an outside upper forming an outer appearance and an inside upper adhered to a foot; a top of foot protection upper installed inside the U-shaped boot upper rim; and a tightening band tied between the boot upper rims in a zigzag shape outside the top of foot protection upper, the apparatus includes: a top of foot tightening means installed inside the top of foot protection upper, for compressing the top of the foot to the sole; a wire passing through the top of foot tightening means, and pulling the top of foot tightening means to the top of the foot so that the heel can be fixedly adhered to the sole; and a wire fixing device connected to both ends of the wire, for selectively pulling or releasing the wire. [0020] A pair of sole holes are formed on the sole of the boot to pass through the right and left sides, bottom end holes and rear holes are formed in pairs on the bottom end and the rear portion of the inside upper of the boot, four holes are formed at one side top end of the inside upper of the boot, the wire fixing device is installed on the wire passing through the four holes, and the wire passing through the bottom end holes and the rear holes draws the top of foot tightening means inside the boot. [0021] The wire fixing device includes a round inside plate, and a round outside plate performing a relative rotation to the inside plate. A plurality of rotary gears are installed inside the inside plate, when the outside plate is rotated in the clockwise direction, the wire is drawn into the inside plate and tightened, and, when the outside plate is outwardly pulled from the inside plate, rotation of the rotary gears is stopped and the wire is loosened.
