However, it will be appreciated that the embodiments and the drawings are given for the purpose of mere illustration and explanation and that the scope of the present invention is to be defined by the appended claims. In the drawings annexed, the same reference numerals denote the same or corresponding parts throughout several views. FIRST EMBODIMENT Hereinafter, a first embodiment of the invention will be described with reference to the drawings. In this first embodiment, the principle embodiment is shown and the basic structure and principle of this invention will be described. FIG. 1(a) and FIG. 1(b) are schematic sectional views of a shoe sole S in the middle foot part, i.e., arch region of the foot. The arrow F is the direction toward the front of the shoe and the arrow B is the direction toward the rear or back of the shoe. As shown in FIG. 1(a), the shoe sole S comprises an outer sole 1, a midsole 2 and a reinforcing member 3 for reinforcing the midsole 2. The outer sole 1 is divided at just under the arch of the foot into a fore foot part 1 f and a rear foot part 1 b. Each part 1 f, 1 b of the outer sole 1 has a ground contact surface 15 which has ground contact at the time of landing, and a top surface 16 opposite to the ground contact surface 15. As shown in FIG. 1(a), the midsole has a top surface 26 and a bottom surface 25. A part of the bottom surface 25 of the midsole 2 is attached to the top surface 16 of the outer sole 1 so as to cover the outer sole 1 from above. At a bottom portion 22 of this midsole 2, a first arch 2 c is formed just under the arch of the foot. The first arch 2 c is formed by hollowing out the bottom surface 25 of the midsole 2 in an arch shape to thus form a concave bottom surface 29 in the first arch 2 c. The top surface of the first arch 2 c has a third curve surface 120 which is curved convex upwards so as to be approximately along the arch of the foot. The third curved surface 120 is gently curved in the central region in the widthwise direction and is largely curved in the medial region. The reinforcing member 3 has a second arch 3 c, a fore end part 3 f in front of the second arch 3 c and a rear end part 3 b in the rear of the second arch 3 c. As shown in FIG. 1(a), the second arch 3 c is formed to bulge upwards. A top surface 36 of the second arch 3 c is a curved face which is convex upwards, the bottom surface 35 of the second arch 3 c being a curved face which is concave downwards. That is, the bottom surface 35 of the second arch 3 c has a fourth curved surface 130 which is recessed upwards. The reinforcing member 3 is arranged so that the second arch 3 c is covered with the first arch 2 c from above. The reinforcing member 3 is supported with its fore and rear end parts 3 f, 3 b sandwiched in between the outer sole 1 and the midsole 2. That is, as shown in FIG. 1(a), the fore end part 3 f is sandwiched in between the top surface 16 of the fore foot part 1 f of the outer sole 1 and the bottom surface 25 of the midsole 2 and the rear end part 3 b is sandwiched in between the top surface 16 of the rear foot part 1 b of the outer sole 1 and the bottom surface 25 of the midsole 2 so that the reinforcing member is supported. This reinforcing member 3 maintains the strength of the shoe sole S at the position corresponding the first arch 3 c and prevents distortion of the shoe sole S. Accordingly, the Young's modulus of the reinforcing member is set to be larger than that of the first arch 2 c of the midsole 2. As shown in FIG. 1(a), the top surface 36 of the second arch 3 c and the bottom surface 29 of the first arch 2 c of the midsole 2 are arranged so as to be opposite to each other. Thus, the top surface 36 of the second arch 3 c and the bottom surface 29 of the first arch 2 c are vertically spaced from each other so that they are not in contact with each other. These surfaces 36, 29 are not in contact with each other and define a domain R, which is hollow. As shown in FIG. 1(b), when the foot lands on the ground, impact load W1 is applied to the ground contact surface 15 of the outer sole 1 of the shoe sole S. At this time, an impact load W1 is transmitted to the sole of the foot via the outer sole 1 and the midsole 2. Simultaneously, a load W2 from the sole of the foot (from above) is applied to the midsole 2. Due to the load W2 from above, the midsole 2 is compressed and sinks down. At this time, since the first arch 2 c is placed so as to be spaced from the second arch 3 c of the reinforcing member 3, the bottom surface 29 of the first arch 2 c and the top surface 36 of the second arch 3 c deform independently from each other. That is, the sinkage (deflection) of the bottom surface 29 of the first arch 2 c is not impeded by the reinforcing member 3. Because of this sinkage (deflection) of the midsole 2, the fitting property of the midsole 2 with respect to the sole of the foot is improved and the �upthrust� at the time of landing of the foot is decreased or suppressed. In this case, it is preferred that, when the impact load of landing is applied, downward displacement of the non-contact area of the bottom surface 29 of the first arch 2 c is set larger than downward displacement of the non-contact area of the top surface 36. Such setting allows thrust-up feeling from below to be reduced more. On the other hand, the reinforcing member 3 is difficult to deform due to its curved shape and the Young's modulus of the reinforcing member 3 is set larger than that of the midsole 2. Accordingly, the rigidity and strength of the shoe sole S is maintained and distortion of the midsole 2 is prevented. FIG. 1(c) and FIG. 1(d) show the modified examples. In the example shown in FIG. 1(c), protrusions 121, 131 are formed on a part of the first arch 2 c and on a part of the second arch 3 c, respectively, and the protrusions 121, 131 of the first and second arches 2 c, 3 c are in contact with each other. In this case, the protrusions 121 of the first arch 2 c have relatively large compression deformation whereas the non-contact areas of both arches 2 c, 3 c deform independently from each other. Accordingly, in this example, the midsole 2 has the aforedescribed function of sinking down, i.e., deflects and compresses downward. As shown in FIG. 1(d), a hole 23 is provided in the bottom surface 29 of the first arch 2 c and a protrusion 33 engagable with the hole 23 is provided on the top surface 36 of the second arch 3 c. The fore and rear end parts 3 f, 3 b need not be sandwiched between the outer sole 1 and the midsole 2. As shown in FIG. 1(c) and FIG. 1(d), both end parts 3 f, 3 b may merely be attached or bonded to the outer sole 1. SECOND EMBODIMENT Next, a second embodiment will be described with reference to FIG. 2, FIG. 3, FIG. 4 and FIG. 5. In the following description of embodiments, the parts which are identical or corresponding to those of the first embodiment are designated by the same reference numerals as the first embodiment and the detailed description and illustration thereof will be omitted. FIG. 2(a) is a side view showing the shoe sole S with an outer sole 1 f, 1 b attached. FIG. 2(b) is a bottom view showing the shoe sole S without the outer sole attached. As shown in FIG. 2(a), the shoe sole S comprises an upper midsole body 28, a lower midsole body 27 and a reinforcing member 3. In this embodiment, the upper and lower midsole bodies 28, 27 constitute the midsole 2. The lower midsole body 27 is divided at the position corresponding to the arch of the foot into a front part 27 f and a rear part 27 b. The fore foot part 1 f of the outer sole 1 is attached to the bottom surface 25 f of the front part 27 f and the rear foot part 1 b of the outer sole 1 is attached to the bottom surface 25 b of the rear part 27 b. As shown in FIG. 4, in the upper midsole body 28, the first arch 2 c is provided at the position corresponding to the arch of the foot. In the reinforcing member 3, the second arch 3 c is provided. The reinforcing member has a fore end part 3 f in front of the second arch 3 c, a rear end part 3 b in the rear of the second arch 3 c, a lateral side part 30 on the lateral side of the second arch 3 c and a medial side part 31 on the medial side of the second arch 3 c. Referring to FIG. 3, the lower midsole body 27, the upper midsole body 28 and the reinforcing member 3 are combined with each other. In this combination, the fore and rear end part 3 f, 3 b of the reinforcing member 3 are sandwiched in between the upper and lower midsole bodies 28, 27, and the medial and lateral side parts 31, 30 are joined to the upper midsole body 28. In the front part 27 f and the rear part 27 b of the lower midsole body 27, joining faces 51 a, 51 b are provided where the fore and rear end part 3 f, 3 b of the reinforcing member 3 are joined. Referring to FIG. 4, in the upper midsole body 28 joining faces 52 a, 52 b are provided where the fore and rear end part 3 f, 3 b of the reinforcing member 3 are joined and joining faces 53 a, 53 b are provided where the medial and lateral side parts 31, 30 are joined. As shown in FIG. 11, in the assembled shoe sole S, the first arch 2 c and the second arch 3 c are covered with the middle foot part of the foot. That is, the center line 82 of the first arch 2 c of the midsole 2 and the second arch 3 c of the reinforcing member 3 in the longitudinal direction is in proximity of the center line 81 of the arch of the foot in the longitudinal direction. For example the center line 82 may be located so as to pass through the navicular bone 75 and the cuneiform bone 77. Optionally, the center line 82 of the first arch 2 c and the second arch 3 c may be located so as to pass through the cuboid bone 76. Thus, there are a range of positions for the center line 82 with respect to the arch of the foot. Further, as shown in sectional view FIG. 5(a), the bottom surface 29 of the first arch 2 c and the top surface 36 of the second arch 3 c are arranged so that they are opposite to each other and that they are vertically spaced from each other. Accordingly, when the foot lands on the ground, the upper midsole body 28 sinks down toward the second arch 3 c, similarly to the first embodiment. As shown in FIG. 4, on the bottom surface 29 of the first arch 2 c, first curved surfaces 62, 62 which are concave in the circular arc shape are provided at the medial and lateral portions of the first arch 2 c. As shown in FIG. 5(a), on the bottom surface 29 of the first arch 2 c, such curved surfaces 62, 62 are also provided at the front and rear end portions of the first arch 2 c. The central area of the bottom surface 29 of the first arch 2 c is very gently curved or is substantially flat or planar. As shown in FIG. 3, on the top surface 36 of the second arch 3 c, second curved surfaces 63, 63 which are convex upwards in a circular arc shape are provided at the medial and lateral portions. As shown in FIG. 5(a), on the top surface 36 of the second arch 3 c, such second curved surfaces 63, 63 are also provided at the front and rear end portions of the second arch 3 c. The remaining area of the top surface 36 of the second arch 3 c (for example, the central area) is very gently curved or is substantially flat or planar. The first and second curved surfaces 62, 63 are formed approximately in the circular arc shape with a center line along the transverse direction as a center. The first and second curved surfaces 62, 63 are arranged so as to be opposite each other. That is, the two surfaces 62, 63 face opposed to each other. Further, as shown in a sectional view of FIG. 5(b), the fore and rear end parts 3 f, 3 b of the reinforcing member 3 and lateral side part 30 and medial side part 31 of the reinforcing member 3 are joined to the upper midsole body 28. That is, entire of the peripheral edge of the reinforcing member is joined to the upper midsole body 28. Such a joint improves the functions of preventing the bend of the shoe and preventing the distortion of the shoe. That is, the bend and distortion of the shoe is prevented or minimized. Such functions of preventing the bend of the shoe and preventing the distortion of the shoe will be explained. The function of preventing the bend of the shoe, in view of the sectional shape, correlates with moment of inertia of area Iy (second moment of inertia, geometrical moment of inertia) with respect to a neutral axis. In this embodiment, since entire of the peripheral edge of the reinforcing member 3 is joined to the upper midsole body 28, the reinforcing member 3 integrally bends together with the upper midsole body 28. Thus, the moment of inertia of area Iy increases by spacing the reinforcing member 3 away from the bottom surface of the upper midsole body 28. Accordingly, the function of preventing the bend of the shoe is improved. On the other hand, the function of preventing the distortion of the shoe, in view of the sectional shape, correlates with polar moment of inertia of area Ip with respect to a centroid. In this embodiment, since entire of the peripheral edge of the reinforcing member 3 is joined to the upper midsole body 28, the reinforcing member 3 is integrally distorted together with the upper midsole body 28. Thus, the polar moment of inertia of area Ip increases by spacing the reinforcing member 3 away from the bottom surface of the upper midsole body 28. Accordingly, the function of preventing the distortion of the shoe is improved. Further, referring to FIGS. 3 and 4, by joining the entire peripheral edge 37 of the reinforcing member 3 to the upper midsole body 28, a sealed or closed space (domain) R is formed between the upper midsole body 28 and the reinforcing member 3 (see FIG. 5(a)). That is, the bottom surface 29 of the first arch 2 c of the upper midsole body 28 and the top surface 36 of the second arch 3 c of the reinforcing member 3 define the sealed or closed domain R. In such joint structure that encompasses the entire peripheral edge 37 of the reinforcing member 3, the air confined in the domain R supports the first arch 2 c softly, thereby to prevent the first arch 2 c of the upper midsole body 28 from sinking down too much. Each of the upper and lower midsole bodies 28, 27 is preferably made of a foamed ethylene-vinyl acetate copolymer (EVA). However, the upper and lower midsole bodies 28, 27 may be made of a foam of another type resin. It is preferred that both upper and lower midsole bodies 28, 27 be made of the same material in order to improve the adhesiveness between the upper and lower midsole bodies 28, 27 so that they can support the reinforcing member 3 in a stable manner. The reinforcing member 3 may be made of a non-foam of polyurethane, or may be made of foam or non-foam of other resin. Examples of resin materials that can be used to make the reinforcing member 3, are nylon, fiber reinforced plastic (FRP), carbon fiber reinforced plastic (CFRP), polyamide, polyester, polypropylene, polyvinyl chloride (PVC), acrylonitrile-butadiene-stylene (ABS), styrene. It is preferred that a non-foam resin, which has certain strength and is easy to mould, is used as the material for the reinforcing member 3. In addition, when the reinforced member 3 is formed of transparent resin, the quality of the design of the shoe is improved. A preferred transparent resin that may be used is a non-foam polyurethane or EVA, which can readily adhere to foamed EVA, the main material of the midsole. The midsole 2 in this embodiment is divided to the upper and lower midsole bodies 28, 27, but the midsole 2 need not necessarily be so divided. The midsole 2 may be formed integrally, i.e. an integral one-piece unit. The shoe sole may be assembled with a shock absorbing material, such as gel, enclosed within the midsole 2. Referring to FIG. 4, the first curved surface 62 of the first arch 2 c is provided at both the medial portion and the lateral portion of the first arch 2 c, but the first curved surface 62 may be provided at either the medial portion or the lateral portion of the first arch 2 c or may be provided continuously from the medial portion to the lateral portion of the first arch 2 c. The second curved surface 63 of the second arch 3 c can be provided in a similar way to the first arch 2 c. THIRD EMBODIMENT FIG. 6(a) is a longitudinal sectional view of a shoe sole according to a third embodiment. As shown in FIG. 6(a), a first reinforcing member 39 and a second reinforcing member 40 are provided. The second reinforcing member 40 is a different member from the first reinforcing member 39. The second reinforcing member 40 is located below the first reinforcing member 39. The first reinforcing member 39 corresponds to the reinforcing member 3 according to the above-mentioned first and second embodiments and has the second arch 3 c. The second arch 3 c is arranged to be opposite to the first arch 2 c of the midsole 2 and to be vertically spaced from the first arch 2 c. On the other hand, the second reinforcing member 40 is for reinforcing the first reinforcing member 39. Such second reinforcing member 40 further prevents the distortion of the shoe sole at the arch of the foot. In the example of FIG. 6(a), a fore end part 40 f and a rear end part 40 b of the second reinforcing member 40 are sandwiched in between the midsole 2 and the outer sole 1. Optionally, as shown in FIG. 6(b), the fore and rear end parts 40 f, 40 b may be sandwiched in between the lower midsole body 27 and the upper midsole body 28, or, as shown in FIG. 6(c), may be sandwiched between the lower midsole body 27 and the outer sole 1. The second reinforcing member 40 is curved, similarly to the first reinforcing member 39, below the second arch 3 c of the first reinforcing member 39, or may be substantially flat as shown in FIG. 6(c). The Young's modulus of the second reinforcing member 40 may be set different from that of the first reinforcing member 39. It is preferable that Young's modulus of the second reinforcing member 40 is set approximately equal to that of the first reinforcing member 39 or that the Young's modulus of the first reinforcing member 39 is set smaller than that of the second reinforcing member 40. FOURTH EMBODIMENT FIG. 7(a), FIG. 7(b) and FIG. 7(c) is sectional views of a shoe sole according to a fourth embodiment. As shown in the transverse sectional view of FIG. 7(a), the first reinforcing member 39 is attached to a bottom surface 28 b of the upper midsole body 28 and belt-like grooves 61 which extend approximately along the lengthwise direction of the shoe are formed on the bottom surface 28 b of the upper midsole body 28. At the positions where the grooves 61 are formed, as shown in the longitudinal sectional view of FIG. 7(b), the bottom surface 29 of the first arch 2 c and the top surface of the second arch 3 c are vertically spaced from each other so that hollow portions R are formed. Accordingly, at the positions where the grooves 61 are formed (for example, the position indicated by the line VIIb-VIIb of FIG. 7(a)), the upper midsole body 28 can sink down similarly to the above-mentioned embodiments. On the contrary, at the positions where the grooves is not formed (for example, the position indicated by the line VIIc-VIIc of FIG. 7(a)), as shown in the longitudinal sectional view of FIG. 7(c), the top surface 36 of the second arch 3 c is in contact with the bottom surface 29 of the first arch 2 c. FIFTH EMBODIMENT FIG. 12(a) and FIG. 12(b) are sectional views of a shoe sole according to a fifth embodiment. As shown in a longitudinal sectional view of FIG. 12(a), a film-like member 91 is laminated and fixed onto the bottom surface 29 of the first arch 2 c of the midsole 2. Thus, the bottom surface 29 of the first arch is reinforced, and so the bottom surface 29 of the first arch 2 c is prevented from sinking down too much. Accordingly it becomes possible to form the first arch 2 c of the midsole thinner. The film-like member is formed to be thinner than the second arch 3 c of the reinforcing member 3. In this embodiment, in order to obtain a desirable function of suppressing �upthrust� with the bottom surface 29 of the first arch 2 c sinking down, the rigidity ratio of the film-like member 91 and the reinforcing member 3 is preferably set within a certain range. That is, a ratio of a product of multiplication between the average thickness T91 and the Young's modulus E91 of the film-like member 91 to a product of multiplication between the average thickness T3c and the Young's modulus E3c of the second arch 3 c is set approximately � or less (i.e. T91�E91/(T3c�E3c)≦about �). It is speculated that the ratio is preferably set approximately ⅙ or less and that the ratio is more preferably set approximately 1/10 or less. Further, it is preferred that the ratio is set at least approximately 1/1000 or more, and it is more preferred that the ratio is set approximately 1/100 or more. Such setting allows the film-like member 91 to have a certain rigidity, thereby to prevent the bottom surface of the first arch 2 c from sinking down too much The thickness of the film-like member is set, for example, within a range of approximately 0.01 mm to 0.2 mm. The thickness of the second arch 3 c is preferably set approximately 1.0 mm or more, and more preferably set within a range of approximately 1.5 mm to 3.0 mm. In this embodiment, as shown in a transverse sectional view of FIG. 12(b), the first arch 2 c and the reinforcing member 3 are divided into two in the transverse direction of the foot, respectively. A lateral side reinforcing member 300 and a medial side reinforcing member 301 have two side parts 302, 302, respectively. Each of the two side parts 302, 302 is joined to the midsole 2, and two closed domains R, R are formed, one in a medial direction and the other in a lateral direction of the foot. FIG. 8(a), FIG. 8(b), FIG. 8(c) and FIG. 8(d) are bottom views of the shoe soles at the first arch of the midsole and show different configurations of the reinforcing member 3. In the above mentioned second embodiment, the reinforcing member 3 covers all of the first arch 2 c. However, the reinforcing member 3 need not always be in such shape. The reinforcing member 3 may be in any shape in which a part of the reinforcing member 3 can be joined to the midsole or the outer sole. Accordingly, the planar shape of the reinforcing member 3 may be formed into, for example, an approximately �I�-shaped planar shape as shown in FIG. 8(a), an approximately �X�-shaped planar shape as shown in FIG. 8(b) or an approximately �N�-shaped planar shape as shown in FIG. 8(c). Further, as shown in FIG. 8(d), the reinforcing member 3 may be formed so as to have an opening 70 vertically passing through the second arch 3 c in the center of the reinforcing member 3. Although the invention has been described hereinbefore in connection with its preferred embodiments with reference to the accompanying drawings, those skilled in the art could easily imagine various modifications and corrections within the scope of apparent range in view of the description thus far made. For example, the reinforcing member which is provided with the shoe sole may be divided into a medial piece and a lateral piece, or the reinforcing member may be provided with only either the medial side of the foot or the lateral side of the foot. A foam or a filler which has a smaller Young's modulus than the midsole and which is capable of varying its volume may be fitted in the domain between the first arch and the second arch. Therefore, such modifications and corrections should be interpreted to fall within the scope of the invention, as defined by the following claims.
