- the outsole 4 is formed by integrally molding a material such as rubber, synthetic resin, or elastomer. These materials may be used alone, or may be used by mixing or laminating. Further, by using non-foamed or low-foamed materials for these materials, the strength and wear resistance of the outsole 4 can be improved. Further, although not described in detail here, the bottom surface of the outsole 4 is appropriately provided with grooves so as to improve design and drainage and grip.
- the outsole 4 is configured to guide a foot pressure center which is a pressure center exerted on the sole of the foot along the protruding portion by forming a predetermined portion of the lower surface protruding. That is, the outsole 4 includes a sole body 41 disposed corresponding to the foot portion, and a heel protrusion portion 42 (corresponding to a wide area protrusion portion) formed to protrude downward in the heel portion F1 of the sole body 41.

- the tip of the foot pressure ridge 43 is disposed further outside the base of the fourth toe T, for example, outside the fifth toe (little finger), the body tries to incline the body inward.
- the force works too early, causing the ankles and knee joints to valgus and stressing the joints such as the toes and ankles, represented by the hallux valgus.
- the tip of the foot pressure ridge 43 is placed inside the base of the 4th toe T, for example, on the toes around the 2nd finger, the force to fall the body outward will be greatly affected.
- the center of gravity swings to the left and right, and it becomes unstable and stress opposite to the stress on the joint is applied to the joint. Therefore, it is necessary to position the tip of the foot pressure ridge 43 at the toe portion around the base of the fourth toe T in order to stabilize the movement of the center of gravity and reduce or eliminate stress on the joint portion.
- the partial force corresponding to the heel portion F3 and toe portion F4 of the foot pressure ridge 43 is extended so as to substantially overlap the straight line connecting the center of the heel protrusion 42 and the base of the fourth toe T As a result, the above effect can be obtained remarkably.

- the lance protrusion 44 protrudes from both left and right sides of the base end portion of the foot pressure protrusion 43 and to both ends in the width direction of the lower surface of the sole body 41. It is installed.
- This non-protruding ridge 44 is an initial part of the foot pressure center movement process, particularly when the foot pressure center moves from the heel protrusion 42 to the foot pressure ridge 43.
- This is a ridge provided to return the center of foot pressure to the foot pressure ridge 43 side when it is moved to the left and right, and its protrusion is slightly smaller than the foot pressure ridge 43 as shown in Fig. 5. Is set.
- the balance protrusion 44 is also set so that the protrusion amount gradually decreases from the buttock F1 side toward the arch F2 side, and the decrease rate of the protrusion amount is larger than the decrease rate of the foot pressure protrusion 43. It is set. Therefore, the difference in the protruding amount between the balance protrusion 44 and the foot pressure protrusion 43 is gradually enlarged toward the toe side. Thus, the center of the foot pressure can be more reliably guided to the foot pressure ridge 43 by gradually increasing the difference in the protrusion amount of each ridge 43, 44 toward the toe side.
- the pair of balance protrusions 44 are formed continuously on the left and right protrusions 42 on both the left and right sides, and extend along the left and right side edges of the sole body 41, and their tips are both of the arch part F2. It arrange
- the width of the balance protrusion 44 is constant in the longitudinal direction and is narrower than the foot pressure protrusion 43.

- FIG. 7B shows the floor reaction force in the foot longitudinal direction (front is positive)
- FIG. 7C shows the reaction in the vertical direction (upward is positive). The power distribution is shown.
- the foot pressure center is swung outwardly from one end and is suddenly turned back inward in both cases of bare feet and when wearing any shoes.
- the runout width Sx is the smallest compared to the other cases. That is, with this measurement result force, the foot pressure center is moved more linearly by wearing the shoes 1 of the present embodiment and walking, etc., with the left and right swing of the foot pressure center being smaller. It can be seen that smooth and quick walking movements are possible.
- the swing width Sx can be suppressed to a relatively small value, so that excessive force is applied to the legs and the waist to suppress the swing. As a result, muscle movements during walking and running are performed flexibly and smoothly, which can effectively reduce the burden on the skeleton and muscles of the legs.
- the floor reaction force at the time of landing acts in the opposite direction to the floor reaction force at the time of takeoff and indicates the force acting in the vertical direction. Increase the force In other words, the floor reaction force at the time of landing acts as a brake against the propulsive force. Therefore, the greater the reaction force at the time of landing, the more the propulsive force will be reduced. Based on the braking force of the! /, Will put an excessive burden on the skeleton and muscles of the legs. In this regard, it can be seen that when the shoe 1 of the present embodiment is worn, the maximum floor reaction force Syl is much smaller than in other cases.
- the maximum floor reaction force Sz when the shoe 1 of the present embodiment is worn acts in substantially the same manner as in other cases.
- the most efficient and smooth generation of thrust can be achieved with the same level of force. It is possible to move the center of the foot pressure naturally without using extra force, that is, suppressing the influence on the skeleton and muscles of the legs and hips as much as possible.
- the heel protrusion 42 is provided on the bottom surface of the heel F1 of the sole body 41. First of all, the landing of the heel protrusion 42 is urged. Since the heel protrusion 42 protrudes from a predetermined region including the central portion on the lower surface of the heel F1, the foot pressure center can be first applied to the center of the heel F1. Subsequently, when the foot pressure ridge 43 contacts the foot pressure center, the foot pressure center can be concentratedly applied to the foot pressure ridge 43, and the foot pressure center can be collected on the foot pressure center path.
- the center of the foot pressure is a predetermined foot pressure center path directed toward the base of the fourth toe.
- this shoe 1 can always guide the center of foot pressure associated with walking and running movement around the base of the 4th toe, keeping the focus inside.
- the force acts properly to suppress the left / right swing of the center of gravity as much as possible to efficiently transmit the propulsive force, and naturally rotate the thighs using the hip joints, and unnecessarily muscles Because it can reflexively swing out the lower limbs and sole without tension
- it is possible to easily perform optimal walking and running operations. Therefore, it is possible to reduce the burden on the skeleton and muscles of the legs, and to perform a stable and smooth walking and running operation regardless of the way of walking and running.
