Abstract: The insole has a number of flexible bulges on a first major surface, and a number of protruding ribs on a second major surface. The projections of the bulges fall within the regions bounded by the ribs. The bulges and their underlying bounding ribs therefore form a number of chambers. The insole further contains a number of through holes positioned between the ends of at least two ribs. The insole further contains a larger heel bulge provided on the first major surface in the heel section, and a concave on the second major surface, which is conducted to the other chambers via at least a duct.

Abstract: The sole device contains a bottom sole, a middle sole, and a top sole stacked in this order from bottom to top. A large number of air chambers are formed between the top and middle soles. The air chambers are interconnected with lateral ducts and the ducts are connected to the top and bottom surfaces of the top and middle soles by a number of vertical channels, respectively. The ducts and air chambers are further connected to one-way valves configured around the circumferences of the middle and bottom soles. As a user walks, the air chambers are periodically pressed to expel warm and humid air to the outside of the shoes via the ducts, channels, and the one-way valves. The one-way valves prevent water or rain from permeating into the shoes.

Abstract: A shoe sole includes a bottom, an insole, and a midsole. The insole forms a plurality of air passages extending therethrough, and has a bottom face on which a plurality of first raised sections is formed to delimit a plurality of first air chambers. The midsole is positioned between the insole and the bottom and has a top face opposing the bottom face of the insole and forming a plurality of second raised sections that delimits a plurality of second air chambers, the second raised sections being configured to correspond in position to the first raised sections so that when the midsole is stacked on the insole, the first raised sections are respectively positioned on the second raised sections and the first air chambers respectively correspond to the second air chambers to form combine air chambers that each have an increased volume.

Abstract: A ventilating structure for a shoe is provided, which contains a duct member containing a number of air ducts communicating with a plurality of through holes at the sole's rim, a first pad member having a plurality of through holes on top of the duct member, a semi-spherical bubble member fixedly attached to the top of the first pad member covering at least a through hole of the first pad member directly above an air duct of the duct member, and a second pad member on top of the first pad member having a number of through holes and a bulged section accommodating the bubble member. As a user walks on a shoe of the invention, the bubble member, like a pump, undergoes intermittent compressions and releases by the user's foot, causing warm and humid air to be expelled out or fresh air to be drawn inside of the shoe quickly and periodically.
