An insole which generates an air flow during use, which assists in cooling or warming the foot of a user is disclosed. In a first embodiment, air flow facilitated by said insole provides for convective heat transfer away from the plantar surface of the foot. The insole is intended for insertion into a shoe which is ventilated, preferably an athletic shoe with a ventilated upper. The bottom layer defines a plurality of ridges and channel lining portions which together define a plurality of air channels. The bottom layer defines a heel recess in which a heel pad is situated. In a second embodiment, an insole which collects, retains, and heats a user's foot is disclosed. Said insole further comprises a middle layer of thermal reflective material secured to and coextensive with a top layer and a bottom layer secured to said middle layer.

The name of the invention: One-way membrane with a barrier protection, which ensures the function of permeability even in the case of contradirectional mechanical pressure, and the method of its manufacture. The invention relates to a single-layer or multilayer membrane (1) with through apertures (2), whose face layer (1) is connected with thin flexible plastic or rubber segments (3) overlapping the apertures (2) and allowing the air or fluid to flow only in the direction from the underside layer (12) of the membrane (1) to the face layer (11) of the membrane (1), as check valves/flaps in the number of up to 30 pieces per 1 cm.sup.2. It further relates to the method of manufacturing the membrane (1).

A shoe component includes a base structure which is substantially shaped so as to reproduce at least partially the sole of a foot of a user, the base structure having an upper surface which is designed to be directed toward the foot and a lower surface which is opposite the upper surface, the component comprising one or more through holes and one or more blind holes provided in the base structure. The one or more through holes are in communication with one or more of the one or more blind holes through one or more channels provided in the base structure.

The three invention's utility designs can be used for all types of footwear, including slippers and sandals for indoors, outdoors, SPA, hotel slippers and etc. The first core invention are removable and washable insoles/socks that are pulled over/attached to the base/hard insole of slippers with options when upper parts are also detachable. The second invention is the closed-toes slippers with ventilation holes both on the cloth insole and upper part with option to have it combined with the first invention. The third invention's distinction is the giant size of slippers that are worn over the outdoor footwear that can also have options with the removable sock or ventilation holes from inventions mentioned earlier. There are different details variations described in specifications for all three interrelated inventions. These slippers provide more hygiene, can be worn longer, which is more economical for households and reduces waste produced by slippers.

Disclosed is a waterproof shoe with an improved ventilation mechanism, designed to circulate air from the outside environment through the shoe in order to provide convective cooling to a wearer's foot. In a desired embodiment, the shoe may incorporate a pump-ventilation mechanism which, coupled with airflow channels incorporated in the upper, acts to establish continuous substantially one-way airflow through the shoe in a heel-to-toe direction while a user walks.

Provided are footbeds having multiple points of contact and varying compression rates for use in articles of footwear. In one embodiment, a footbed may include apertures (for example, ovals) arranged in a varying grid density. In another embodiment, a footbed may include a lattice having edges that define polygons arranged in a constant grid density. In another embodiment, a footbed may include a lattice having edges that define polygons arranged in a constant grid density and having protruding structures within each polygon.
