Title:
SHOE SOLE STRUCTURE
Document Type and Number:
Japanese Patent JP3403952
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a shoe sole structure by which the rigidity of the arch of a foot is improved while the cushion performance and stability are secured in the shoe sole structure used for the sports shoes to inhibit the arch of the foot from sinking in or being twisted and realize comfortable running as the whole of the shoe sole.
SOLUTION: The shoe sole structure comprises an out sole 6, the heel part of which is rich in wear resistance and non-slip performance and two, upper and lower mid-soles 4, 5 which are flexible and rich in elasticity, wherein a waveform plate 1 made of raw material harder than the mid-sole part is clamped between both mid-soles to make the cushion performace and stability of the heel part compatible with each other. Further, the inner instep side and outer instep side of the arch part of the sole are elongated as shank parts 2, 3 from the front end part of the plate integrally with the plate 1 to reduce the weight of the sole, load (body weight) can be smoothly transferred to the front foot part from the heel landing time, and the occurrence of trouble of the foot part can be decreased.
