Support structure for reinforcing non- tread face section of especially trainer shoe has front supported section and rear supported section either side of integrated curved section to prevent flattening

摘要

The support structure has an integrated curved section (3a) fixed on a rear face of the non tread section of a mid sole, an integrated front supported section mounted in front of the curved section, and an integrated rear supported section behind the curved section. The front and rear support sections (30, 31) are clamped between an outsole (1) and a mid sole (2) of the shoe sole (S) when subjected to load (W) from above. The front supported section is held by a tapering first inclined surface (10) inclined so that it rises forwards (F). The front supported section is prevented from moving in a direction where the curved section would open when the sole contacts the ground.
