Description

TECHNICAL FIELD The present invention relates to a sock that improves the weight balance on the sole of the foot during exercise.

BACKGROUND ART Conventionally, socks have been known that improve the weight balance applied to the soles of the feet during exercise. As this type of sock, a strip-shaped first low-stretch region 100 having a lower stretchability than other regions is provided on the dorsum of the foot. The center line C of the course direction width of 100d extends to the base of the toes while gradually shifting toward the fifth toe, and the lower end 100b extends from the base of the third toe to the base of the fifth toe. (see FIG. 9). In addition, the side portion 101c on the side of the fifth toe in the vicinity of the lower end is configured to extend to the sole so as to involve the fifth metatarsal bone (for example, Prior Document 1). By configuring in this way, by hooking the side portion near the fifth toe side near the lower end of the first low-elasticity region 100 to the fifth metatarsal bone, a force to pull up the entire fifth toe side of the foot can be obtained. Therefore, it was possible to improve the preventive effect of inversion sprain. Here, FIG. 9 is a diagram showing the dorsum side of the conventional sock.

Japanese Patent No. 5255897

However, in conventional socks, the tip side (fifth toe side) of the foot is lifted by pulling up the entire fifth toe side of the foot. 3 points of weight shift, landing from the ground, then moving to the vicinity of the 5th toe, and then moving to the 1st toe. The weight shifts in order from the vicinity to the vicinity of the first toe, and the weight cannot be placed evenly on the three points of the ball of the foot, the ball of the little finger, and the heel. In this way, since the weight cannot be evenly placed on the three points of the ball of the foot, the ball of the little finger, and the heel, the movement efficiency of running cannot be improved, and there is a problem that the user cannot run faster. Since "only the tip of the 5th toe" of the foot is pulled up, the foot cannot supinate sufficiently from the ankle, and there is a possibility of ankle injury such as inversion sprain.

The present invention has been made in view of the above problems, and improves the weight balance on the sole during exercise by placing the weight on the ball of the foot, the ball of the little foot and the heel almost evenly. An object of both is to provide socks that enable faster running by improving motion efficiency of running.

In order to solve the above problems and achieve the above objects, a first aspect of the present invention is a sock that improves the weight balance applied to the sole of the foot during exercising, the sock having a stretch rate greater than that of the periphery. The width is from the 4th metatarsal bone of the sole to the 4th metatarsal bone of the foot through the 5th metatarsal bone, and the longitudinal direction is the length to the front of the cuboid bone. The formed lateral low stretchable part, and the lateral tensile stretchable part, which is generated so that the stretchability is lower than that of the peripheral part, and extends from the third metatarsal bone side of the dorsum of the lateral low stretchable part to at least the medial part of the ankle. and the lateral tensile stretchable portion pulls up the fourth and fifth metatarsals of the lateral side of the foot through the lateral low stretchable portion, thereby making the sole substantially flat and touching the ground. It can be landed on

According to the present invention, the lateral width is the width from the 4th metatarsal bone of the sole to the 4th metatarsal bone of the dorsum through the 5th metatarsal bone by the lateral extension and contraction part, and the longitudinal direction is the width in front of the cuboid bone. The lateral low stretchable part formed by the length is pulled up from the 3rd metatarsal bone side of the dorsum to the medial direction of the ankle, so that the 4th metatarsal bone and the 5th metatarsal bone in contact with the cuboid bone are pulled up. , the foot can be landed on the ground in a substantially flat state. In other words, the whole sole of the foot can be made to land on the ground. As a result, the weight can be placed almost evenly on the ball of the foot, the ball of the little toe and the heel, and the weight balance on the sole during exercise can be improved to enable faster running.

According to a second aspect of the present invention, there is provided a sock that improves the weight balance applied to the sole during exercise, is produced so that the stretch rate is lower than that of the peripheral portion, and the width of the sock is the width of the sole. The width of the range from between the 3rd and 4th metatarsals through the 5th metatarsals to between the 3rd and 4th metatarsals on the dorsum of the foot, to the front of the cuboid bone in the longitudinal direction The lateral low-elasticity part formed with the length and the outer low-elasticity part, which is generated to have a lower elasticity than the peripheral part, extends from the 3rd metatarsal bone side of the dorsum of the lateral low-elasticity part to at least the medial part of the ankle and a lateral extension/contraction part, wherein the lateral extension/contraction part pulls up the 4th and 5th metatarsals of the lateral part of the foot through the lateral low-contraction part, thereby making the sole substantially flat. It can be landed on the ground in a state.

According to the present invention, the lateral extension/contraction part extends from between the third and fourth metatarsals of the sole to the third and fourth metatarsals of the dorsum via the fifth metatarsal. The width of the range between the cuboid bone and the cuboid bone and the cuboid bone by pulling up the lateral low stretchable part formed with the length to the front of the cuboid bone in the longitudinal direction from the 3rd metatarsal bone side of the dorsum to the medial direction of the ankle The 4th and 5th metatarsal bones that are in contact with each other are lifted up, and the foot can be landed on the ground in a substantially flat state. In other words, the whole sole of the foot can be made to land on the ground. As a result, the weight can be placed almost evenly on the ball of the foot, the ball of the little toe and the heel, and the weight balance on the sole during exercise can be improved to enable faster running.

According to a third aspect of the present invention, there is provided a sock according to the first aspect or the second aspect, comprising a thumb pouch for storing the thumb and a middle finger pouch for storing the index finger and the middle finger. and an outer finger bag for accommodating the ring finger and the little finger.

According to the present invention, since the outer finger pouch is provided to accommodate the ring finger and the little finger, the fourth and fifth metatarsal bones in contact with the cuboid bone are further pulled up by the outer tensile stretchable part. This makes it easier to land on the ground with the bottom of the foot in a substantially flat state. As a result, the weight can be placed almost evenly on the ball of the foot, the ball of the little toe and the heel, and the weight balance on the sole during exercise can be improved to enable faster running.

According to a fourth aspect of the present invention, there is provided the sock according to the first or second aspect, wherein the outer stretchable part extends from the third metatarsal bone side of the dorsum of the outer low stretchable part to the inner side of the ankle.

Also, the sock 1 of this embodiment includes a thumb bag 1a for storing the thumb, a middle finger bag 1b for storing the two fingers of the index finger and the middle finger, and an outer finger bag 1c for storing the two fingers of the ring finger and the little finger. are provided (see FIG. 1). Since the outer finger pouch 1c is provided to accommodate the ring finger and the little finger, the fourth metatarsal bone 9 and the fourth metatarsal bone 9, which are in contact with the cuboid bone 11 by the outer extension/contraction part 8, are provided as described later. The 5-metatarsal bone 10 can be pulled up more easily, and the sole can be put in a substantially flat state to make it easier to land on the ground. Specifically, it will be described later. In this embodiment, crew socks 1, which are longer than short socks and longer than high socks, are used for explanation, but the present invention is not limited to this, and socks provided with a body portion 4 and a foot portion 6 may be used. If so, other types of socks such as short socks and high socks may be used, and "pantyhose", "stockings", and "tights" are also applicable. Here, "pantyhose" is clothing that covers the lower half of the body, mainly for women, and is clothing that integrates panties, which are underwear, and stockings, which are long socks, and covers from the toes to the waist in one pair. In addition, "stockings" are leg garments that cover the legs and feet and are in close contact with the skin. It is a stretchy leg garment that wraps around. The description and drawings when applied to pantyhose, stockings, tights, etc. can be easily understood, so the description and drawings are omitted. In this embodiment, the sock 1 includes a thumb bag 1a for storing the thumb, a middle finger bag 1b for storing the two fingers of the index finger and the middle finger, and an outer finger bag for storing the two fingers of the ring finger and the little finger. 1c is provided, but not limited to this, a sock with a finger bag for storing five fingers separately, a thumb bag for storing the thumb and a four-toe bag for storing the other four fingers are provided. Tabi socks or the like may also be used.

Also, the sock 1 is a sock that improves the weight balance applied to the sole during exercise, and is provided with an outer low stretchable portion 7 and an outer stretchable stretchable portion 8 (see FIGS. 1 and 2). .

Next, the relationship between the sock and the foot bones of the first embodiment of the present invention will be specifically described with reference to the drawings. Here, FIG. 3 is a top view showing the relationship between the sock and the foot bone in the first embodiment of the present invention, FIG. 4 is a bottom view showing the relationship between the sock and the foot bone, and FIG. FIG. 6 is a lateral view showing the relationship between the sock and the foot bone, and FIG. 6 is a medial side view showing the relationship between the sock and the foot bone.

The lateral low-elasticity portion 7 is formed to have a lower elasticity than the peripheral portion, and has a width from the 4th metatarsal bone 9 of the sole to the 4th metatarsal bone 9 of the dorsum through the 5th metatarsal bone 10. , and the vertical direction is formed with a length up to the front of the cubic bone 11 (see FIGS. 3 and 4). Specifically, when the sock 1 is worn, the sole (sole) portion of the fourth metatarsal bone 9 of the foot of the sock 1 wearer is wrapped around the outer fifth metatarsal bone 10 from the sole of the foot. It extends from the side of the foot to the dorsum of the fourth metatarsal 9 (instep). In addition, the longitudinal direction of the outer low stretchable portion 7 extends from the tip (front end) of the fourth metatarsal bone 9 to the fifth metatarsal bone 10 to the rear end of the fourth metatarsal bone 9 to the fifth metatarsal bone 10 . It is formed with a width up to the part (rear end). In this way, the outer low stretchable portion 7 is formed so that the fourth metatarsal bone 9 to the fifth metatarsal bone 10 are wrapped around. In this embodiment, the width of the outer low stretchable portion 7 is a width that covers substantially the entire area from the 4th metatarsal bone 9 of the sole to the 4th metatarsal bone 9 of the dorsum via the 5th metatarsal bone 10. , The longitudinal direction is formed to the front of the cuboid bone 11, but not limited to this, the lateral low stretchable part 7 has a width from the fourth metatarsal bone 9 to the fifth metatarsal bone 10 of the sole. It may be formed with a width covering the 4th metatarsal bone 9 of the dorsal foot, and the width may extend from between the 3rd metatarsal bone 12 of the sole and the bone 4th metatarsal bone 9 to the 5th metatarsal bone 10. It may be formed with a width that covers substantially the entire area between the third metatarsal bone 12 of the dorsum of the foot and the fourth metatarsal bone 9, and the width is between the third metatarsal bone 12 and the fourth metatarsal bone of the sole. It may be formed with a width ranging from between the 4th metatarsal bone 9 to between the 3rd metatarsal bone 12 of the dorsal foot and the 4th metatarsal bone 9 via the 5th metatarsal bone 10, and the width is the 4th metatarsal bone. It may be formed with a width ranging from the metatarsal bone 9 through the fifth metatarsal bone 10 to the third metatarsal bone 12 of the dorsal foot and the fourth metatarsal bone 9, and further, the width is the width of the sole. The lateral width is the third middle part of the sole, such as the width from between the third metatarsal bone 12 and the fourth metatarsal bone 9 to the fourth metatarsal bone 9 of the dorsum via the fifth metatarsal bone 10. If the width is within the range from between the foot bone 12 and the fourth metatarsal bone 9 to the third metatarsal bone 12 and the fourth metatarsal bone 9 of the dorsum via the fifth metatarsal bone 10 Both may be width. In addition, in the longitudinal direction of the outer low-stretchable portion 7, from the approximate tip (front end) of the fourth metatarsal bone 9 and the fifth metatarsal bone 10 to the fourth metatarsal bone 9 and the fifth metatarsal bone 10 The width to the substantially rear end (rear end), the substantially front end (front end) of the fourth metatarsal bone 9 and the fifth metatarsal bone 10, the fourth metatarsal bone 9 and the fifth metatarsal bone 10, or from the rear end of the ring finger and little finger to the substantially rear end of the fourth metatarsal bone 9 and the fifth metatarsal bone 10 Any form may be used as long as it is formed with a length up to the front of the cuboid bone 11 in the vertical direction, such as the width up to the (rear end). Even if the outer low stretchable portion 7 is formed in this manner, the fourth metatarsal bone 9 and the fifth metatarsal bone 10 in contact with the cuboid bone 11 can be efficiently pulled up, although the effect is different.

When the sock 1 is knitted, the outer low stretchable portion 7 is knitted by "tuck knitting" in which a plurality of course yarns in the horizontal direction are gathered together to form stitches, and the back yarn is used as a highly stretchable material. The stretchability is reduced by using FTY for the inside and knitting rubber threads. In addition, the peripheral portion (peripheral side portion) of the outer low-elasticity portion 7 is knitted by "flat knitting". Here, "tuck knitting" is a knitting method in which a certain stitch is not made when knitting a fabric, and a stitch is made together when knitting the next course. A knitting method in which a hook or a needle stem is held together with the previous stitch, for example, when forming a stitch by the next supply of yarn, a knitting yarn is pulled out by passing through a plurality of stitches at the same time to create a new stitch. The knitting is performed so that when the stitches are formed by feeding the yarns, the knitting yarn is pulled out through four stitches at the same time to form a new stitch. In this way, in the outer low stretchable portion 7, a highly stretchable material is used and the number of stitches is reduced by "tuck knitting", so that the space of the stitches is reduced and the stitches that can be stretched are reduced. Since the number is reduced, resistance to elongation is exerted, and stretchability is smaller than that of the peripheral portion of the outer low stretchable portion 7 . Since the peripheral portion (peripheral side portion) of the outer low-stretch portion 7 is knitted by “flat knitting”, the portion of the outer low-stretch portion 7 knitted by “tuck knitting” is The expansion ratio is smaller than the peripheral portion (peripheral side portion). In addition, the phrase “produced so that the expansion ratio is lower than the peripheral portion (peripheral side portion) of the outer low-stretchable portion 7” means that the peripheral portion (peripheral side portion) of the outer low-stretchable portion 7 Even if there is a portion with a lower stretch ratio than the low stretchable portion 7, or even if there is a portion inside the outer low stretchable portion 7 with a stretch ratio higher than that of the other outer low stretchable portions 7, the outer low stretchable portion 7 is placed on the outside. A case where the stretchability as a whole is lower than the peripheral portion (peripheral side portion) of the low-stretchable portion 7 is also included. Further, in the present embodiment, the peripheral portion (peripheral side portion) of the outer low-stretchable portion 7 is only in contact with the later-described outer tensile stretchable portion 8 . In this way, since the peripheral portion (peripheral side portion) of the outer low stretchable portion 7 is only in contact with the outer tensile stretchable portion 8, it is affected by other portions that are knitted with low stretchability. The outer low stretchable portion 7 is tightened with a large tightening force. In the present embodiment, the peripheral portion (peripheral side portion) of the outer low-stretchable portion 7 is only in contact with the outer tensile-stretchable portion 8, but this is not the only option. If there is no problem with the tightening function by the outer low-stretchable portion 7, the outer low-stretchable portion 7 may be in contact with the low-stretchable knitting portion other than the outer tensile stretchable portion 8. Further, in the present embodiment, the stretchability is reduced by knitting the outer low stretchable portion 7 by "tuck knitting" and knitting FTY and rubber thread, but this is not restrictive, and FTY and rubber thread are not knitted. good too. Further, in the present embodiment, the outer low stretchable portion 7 is knitted by "tuck knitting", but it is not limited to this, and may be knitted by "cut boss knitting". In this way, by knitting the outer low stretchable portion 7 by "cut boss knitting", the stretchability is reduced, and the "fourth metatarsal bone 9" and "fifth metatarsal bone 10" of the foot have a large tightening. It can be tightened with applied force. Here, "cut boss knitting" means knitting by knitting another yarn in a partial area of the knitted fabric made of the ground yarn when knitting by overlapping another yarn on the ground yarn. In the present embodiment, when the nylon yarn is superimposed on the base yarn and knitted, the nylon yarn is knitted into a partial area of the knitted fabric made of the base yarn. Thus, by using the "cut boss knitting", it is possible to reduce the expansion ratio of the portion knitted by the "cut boss knitting" and improve the tightening force.

The outer stretchable part 8 is formed so that the stretchability is lower than that of the peripheral part, and extends from the third metatarsal bone 12 side of the dorsum of the outer low stretchable part 7 to at least the inner ankle part (substantially the inner ankle part 3 (Fig. 6). See))). In this embodiment, the lateral tensile stretchable portion 8 extends from the lateral low stretchable portion 7 on the side of the third metatarsal bone 12 of the dorsum of the foot to the upper portion of the lateral ankle 3a via the medial portion of the ankle and the posterior portion of the ankle. In this way, the lateral tensile stretchable portion 8 extends from the third metatarsal bone side 11 of the dorsum to the upper portion of the lateral ankle 3a via the medial portion of the ankle and the posterior portion of the ankle. It is possible to sufficiently maintain the force to pull the ankle inward. That is, the fourth metatarsal bone 9 and the fifth metatarsal bone 10 can be firmly and stably pulled up continuously, and the fourth metatarsal bone 9 and the fifth metatarsal bone 10 are in contact with the cuboid bone 11 even during exercise. The bone 10 can be sufficiently stably and continuously pulled up. In the present embodiment, the outer tensile stretchable portion 8 extends from the third metatarsal bone 12 side of the dorsum of the foot of the outer low stretchable portion 7 to the upper portion of the lateral ankle portion 3a via the medial portion of the ankle and the rear portion of the ankle. Socks are used, but not limited to this, from the third metatarsal bone 12 side of the dorsum of the lateral low stretchable part 7 to the inner side of the ankle and the rear part of the ankle (including the approximate Achilles tendon) to the upper part of the substantially lateral ankle part 3a. Also, from the third metatarsal bone 12 side of the dorsal foot of the lateral low stretchable part 7 to the inner side of the ankle and substantially the upper part of the lateral ankle 3a (preferably, the rear part of the ankle and the lateral ankle A sock extending to any position between the substantially upper portion of the portion 3a (the inner portion of the ankle and the rear portion of the ankle may be less effective in some cases) may be used.

The lateral length of the outer low stretchable portion 7 of the outer stretchable stretchable portion 8 in the lateral direction on the side of the third metatarsal bone 12 is formed to be larger toward the ankle. That is, the length of the line extending in the lateral direction from the side of the third metatarsal bone 12 of the outer low stretchable portion 7 of the outer tensile stretchable portion 8 is the front side of the outer stretchable stretchable portion 8 in the direction from the toe to the ankle. It is widely formed obliquely and substantially linearly from the That is, the lateral length shape of the outer low stretchable portion 7 of the outer stretchable stretchable portion 8 in the lateral direction on the side of the third metatarsal bone 12 is formed in a substantially triangular shape. In this way, since the lateral portion of the outer low stretchable portion 7 of the outer stretchable stretchable portion 8 on the side of the third metatarsal bone 12 is formed wider from the toe toward the ankle, the sock becomes wider from the toe toward the ankle. The stretch ratio of 1 becomes low, and the outer low-stretchable portion 7 can be pulled up with a strong pulling force toward the inner side of the ankle. As a result, the fourth metatarsal bone 9 and the fifth metatarsal bone 5 in contact with the cuboid bone 11 can be pulled up with a greater force. In addition, the phrase “formed so that the expansion ratio is lower than the peripheral portion (peripheral side portion) of the outer tensile expansion/contraction portion 8” means that the peripheral portion (peripheral side portion) of the outer tensile expansion/contraction portion 8 is partly formed with an outer Even if there is a part with a lower stretch rate than the tensile stretchable part 8, or even if there is a part inside the outer stretchable stretchable part 8 with a higher stretch rate than the other outer stretchable stretchable parts 8, the outer stretchable stretchable part 8 is A case where the stretchability as a whole is lower than the peripheral portion (peripheral side portion) of the tensile stretchable portion 8 is also included. Further, the peripheral portion (peripheral side portion) of the outer tensile stretchable portion 8 is only in contact with the outer low stretchable portion 7 . In this way, since the peripheral portion (peripheral side portion) of the outer tensile stretchable portion 8 is only in contact with the outer low stretchable portion 7, it is affected by other portions knitting with low stretchability. Instead, the outer low stretchable portion 7 can be pulled up inwardly of the ankle with a large pulling force. In the present embodiment, the peripheral portion (peripheral side portion) of the outer tensile stretchable portion 8 is only in contact with the outer low stretchable portion 7, but the stretchability of the outer tensile stretchable portion 8 is not limited to this. If there is no problem with the tensile function of the outer stretchable portion 8, the outer stretchable stretchable portion 8 may be in contact with a knitting portion having low stretchability other than the outer low stretchable portion 7.

The sock 1 (the length of the crew sock) of the present embodiment is formed with a width of 4 cm to 5 cm in the height direction from the rear part of the ankle of the outer tensile elastic part 8 to the upper part of the outer ankle part 3a (Fig. 5). , see FIG. 6). Here, crew socks generally refer to socks whose length is about mid-length of the calf 13, that is, about 18 cm to 20 cm with the lower point of the heel 14 as the base point. However, when the length is 15 cm or more from the lower point of the heel part 14, the height direction from the rear part of the ankle of the outer tensile elastic part 8 of the sock 1 to the upper part of the outer ankle part 3a may be 4 cm to 5 cm in width. In this way, even when the length of the sock is 15 cm or longer from the lower point of the heel portion 14, the width of the outer tensile stretchable portion 8 can be secured from 4 cm to 5 cm. By setting the width in the height direction from the rear portion of the ankle to the upper portion of the lateral ankle portion 3a to 4 cm to 5 cm, the pulling force of the lateral low stretchable portion 7 toward the medial side of the ankle can be sufficiently maintained. As a result, the fourth metatarsal bone 9 and the fifth metatarsal bone 10 can be firmly and stably pulled up continuously, and the fourth metatarsal bone 9 and the fifth metatarsal bone 10 are in contact with the cuboid bone 11 even during exercise. The foot bone 10 can be sufficiently stably and continuously pulled up. In addition, the low crew socks, which are shorter than the crew socks, have a width of less than 4 cm in the height direction from the rear part of the ankle of the outer tensile elastic part 8 to the upper part of the outer ankle part 3a (for example, 1 cm to 4 cm (preferably 1 cm to 3 cm (more preferably 1 cm to 2 cm).Here, the low crew socks are one-sided socks with a length of about 13 cm to 15 cm from the lower point of the heel part 14 as a base point. is.

As with the outer low-stretchable portion 7, the outer stretchable stretchable portion 8 is also knitted by "tuck knitting" in which a plurality of course yarns in the horizontal direction are gathered together to form stitches when the sock 1 is knitted. At the same time, FTY is used for the back thread as a material with high elasticity, and the elasticity is reduced by knitting rubber thread. Here, since the knitting method and the course yarn of the outer tensile stretchable portion 8 are the same as those of the outer low stretchable portion 7 including the description of the outer low stretchable portion 7, a detailed description thereof will be omitted.

As described above, by using the sock 1 of the present embodiment, the lateral width extends from the fourth metatarsal bone 9 of the sole to the fourth metatarsal bone 9 of the dorsum through the fifth metatarsal bone 10. , the outer low stretchable portion 7 formed with a length up to the front of the cuboid bone 11 in the longitudinal direction is pulled up in the inner direction of the ankle 10 by the outer stretchable stretchable portion 8, so that the fourth metatarsal bone 9 in contact with the cuboid bone 11 and the The fifth metatarsal bone 10 can be pulled up. That is, the lateral part of the sock 1 can be pulled up by pulling up the fourth metatarsal bone 9 and the fifth metatarsal bone 10 with the connecting portion to the cuboid bone 11 as one fulcrum. In this way, by pulling up the outer portion of the sock 1 greatly, the sole can be landed on the ground in a substantially flat state, so that the inner side and the outer side of the sole can be landed on the ground substantially at the same time. . In addition, since the lateral tensile stretchable portion 8 extends from the third metatarsal bone 12 side of the dorsal foot to the upper part of the lateral ankle 3a via the medial portion of the ankle and the posterior portion of the ankle, the lateral low stretchable portion 7 extends to the medial side of the ankle. It is possible to maintain the pulling force in the direction. As a result, the fourth metatarsal bone 9 and the fifth metatarsal bone 10 can be firmly and stably pulled up continuously, and the fourth metatarsal bone 9 and the fifth metatarsal bone 10 are in contact with the cuboid bone even during exercise. The bone 10 can be sufficiently stably and continuously pulled up. As a result, the weight can be placed almost evenly on the three points of the ball of the foot 15, the ball of the little finger 16 and the heel 14, and by efficiently improving the weight balance applied to the sole during exercise, the user can run faster. (See Figure 4). In addition, by providing the outer finger pouch 1c for storing the two toes of the finger and the little finger, the outer tensile stretchable portion 8 further pulls up the fourth metatarsal bone 9 and the fifth metatarsal bone 10 that are in contact with the cuboid bone 11. easier.

On the other hand, if the outer low stretchable portion 7 is formed to cover substantially the entire third metatarsal bone 12, it will be pulled up to the third metatarsal bone 12 that is connected to the intermediate cuneiform bone. Pulling up the third metatarsal bone 12 connected to the intermediate cuneiform bone weakens the lifting force of the fourth metatarsal bone 9 and the fifth metatarsal bone 10 in contact with the cuboid bone 11, so that the outside of the foot can be greatly lifted. Gone. As a result, the weight cannot be placed evenly on the ball of the foot 15, the ball of the little toe 16, and the heel 14, and the weight balance applied to the sole of the foot during exercise becomes slightly unbalanced, reducing running speed. You won't be able to improve much. Further, when the outer low stretchable portion 7 is extended to the cuboid bone 11, the cuboid bone 11 connected to the fourth metatarsal bone 9 and the fifth metatarsal bone 10 is pulled up. By pulling up the cuboid bone 11 that connects the foot bone 9 and the fifth metatarsal bone 10, it becomes impossible to pull up the fourth metatarsal bone 9 and the fifth metatarsal bone 10 with the connecting part to the cuboid bone 11 as a fulcrum. , the lifting force of the fourth metatarsal bone 9 and the fifth metatarsal bone 10 in contact with the cuboid bone 11 is weakened, making it impossible to greatly lift the outside of the foot. As a result, the weight cannot be placed evenly on the ball of the foot 15, the ball of the little toe 16, and the heel 14, and the weight balance applied to the sole during exercise becomes slightly unbalanced. , you won't be able to improve your running speed much.

(Second embodiment)
Next, a sock according to a second embodiment of the present invention will be described with reference to FIGS. 7 and 8. FIG. Here, FIG. 7 is an inner side view showing the relationship between the sock and the foot bone in the second embodiment of the present invention, and FIG. 8 is a bottom view showing the relationship between the sock and the foot bone.

The difference between the second embodiment and the first embodiment is that in the first embodiment, the outer tensile stretchable portion 8 extends from the third metatarsal bone 12 side of the dorsum of the outer low stretchable portion 7 to the medial portion of the ankle and the posterior portion of the ankle. In the second embodiment, the outer tensile stretchable portion 28 extends from the inner side of the ankle to the outer stretchable stretchable portion 8 of the first embodiment. The difference is that the shape extends to the arch of the foot (see FIG. 7). In addition, in the second embodiment, the same reference numerals are used for the same configuration as in the first embodiment, and the same operational effects are achieved, and the description thereof is omitted.

The outer tensile stretchable portion 28 is formed so that the stretchability is lower than that of the peripheral portion, and extends from the third metatarsal bone 12 side of the dorsum of the outer low stretchable portion 7 to the lateral ankle portion 3a via the medial portion of the ankle and the posterior portion of the ankle. It extends up to the upper part and extends from the medial side of the ankle to the arch of the foot (see FIGS. 7 and 8). That is, the lateral tensile stretchable portion 28 extends from the third metatarsal bone 12 side of the dorsal foot of the lateral low stretchable portion 7 to the medial side of the ankle, and is divided into two from there. The other one extends from the medial side of the ankle to the arch of the foot. Here, for the outer tensile stretchable portion 28 of the second embodiment, the above-described portions (including the description) of the outer stretchable stretchable portion 8 of the first embodiment are applied in the same manner, so description thereof will be omitted.

Thus, by using the sock 21 in this embodiment, the width extends from the fourth metatarsal bone 9 of the sole to the fourth metatarsal bone 9 of the dorsum through the fifth metatarsal bone 10, and the vertical Since the lateral low stretchable portion 7 formed with a length up to the front of the cuboid bone 11 is pulled up in the medial direction of the ankle 10 by the lateral tensile stretchable portion 28, the fourth metatarsal bone 9 and the fourth metatarsal bone 9 contacting the cuboid bone 11 5 Metatarsals 10 can be lifted. That is, the lateral portion of the sock 21 can be pulled up by pulling up the fourth metatarsal bone 9 and the fifth metatarsal bone 10 with the connecting portion to the cuboid bone 11 as one fulcrum. In this way, by pulling up the outer portion of the sock 21 greatly, it is possible to land the sole on the ground in a substantially flat state, so that the inner and outer sides of the sole can be landed on the ground substantially at the same time. . In addition, the lateral extension/contraction part 28 extends from the third metatarsal bone 12 side of the dorsum to the lateral ankle part 3a via the medial part of the ankle and the posterior part of the ankle, and extends from the medial part of the ankle to the arch of the foot. As a result, the outer low elastic part 7 can be pulled up from the third metatarsal bone 12 side of the dorsum of the foot of the outer tensile elastic part 28 through the inner ankle part of the outer elastic elastic part 28 with a stable pulling force. As a result, the fourth metatarsal bone 9 and the fifth metatarsal bone 10 can be firmly and stably pulled up continuously, and the fourth metatarsal bone 9 and the fifth metatarsal bone 10 are in contact with the cuboid bone 11 even during exercise. The foot bone 10 can be sufficiently stably and continuously pulled up. As a result, the weight can be placed almost evenly on the three points of the ball of the foot 15, the ball of the little finger 16 and the heel 14, and by efficiently improving the weight balance applied to the sole during exercise, the user can run faster. (See FIG. 8).

It should be considered that the above-disclosed embodiments are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the scope of the claims rather than the above description, and is intended to include all modifications within the scope and meaning of equivalents of the scope of the claims.
