US 6,684,530 B2 · Moisture and temperature regulating insole

Abstract

A moisture and temperature regulating insole for a shoe. The shoe includes a body having a cover and a base layer connected to the cover, and a sole having a base connected to the body and an expansive foam between the body and the base. The insole includes an absorbent layer, an elastic layer, and a closure layer. The insole is connected to the body and to the sole such that the insole absorbs the moist air within the shoe during an advance phase of the foot when the shoe is detached from the ground or floor and delivers the absorbed air with a lower content of moisture and temperature during the support phase of the foot when the shoe is supported on the ground or floor, in part to the environment and in part to the shoe body.

Dependent claims

A moisture and temperature regulating insole for a shoe, the shoe including a body having a cover and a base layer connected to the cover, and a sole having a base connected to the body and an expansive foam between the body and the base, the insole comprising:

an absorbent layer adjacent the base layer;
an elastic layer adjacent the absorbent layer wherein the elastic layer includes an edge contacting the outside environment, the elastic layer being fluidly connected to the outside environment through the edge;
and
a closure layer adjacent the elastic layer and the sole, wherein the insole is connected to the body and to the sole such that the insole absorbs the moist air within the shoe during an advance phase of the foot when the shoe is detached from the ground or floor and delivers the absorbed air with a lower content of moisture and temperature during the support phase of the foot when the shoe is supported on the ground or floor, in part to the environment through the edge and in part to the shoe body.

Summary529 words

#The invention relates to shoes, and more particularly to insoles for shoes.

#In the course of recent years, the shoemaking industry has developed remarkable achievements in both the quality of products that are offered to the market and the cost of these products. Reductions in the prices of these products have resulted in increased availability to almost the entire world population, including even the poorest segments.

#The above mentioned progress has been obtained, in part, by making use of new, modern, and efficient industrial products that are used specifically for the manufacture of soles, uppers or dubs, insoles, and other components. Additionally, specialized designs permit the production of shoes that are designed for specific activities, such as dress, heavy-duty, safety, sport, and other types of footwear.

Detailed description1,442 words

#The drawings illustrate a shoe 10 embodying the invention. The properties of the shoe 10 derive from the coordinated and simultaneous operation of three shoe components (see FIGS. 1-3), namely the body 12, the regulating insole 14, and the sole 16.

#The shoe body 12 includes a cover 18 and a base layer 20 that is preferably an anti-mycotic perforated leather which serves as the foot supporting base and performs the following functions: (i) to fix the shoe 10 to the foot in a comfortable and hygienic manner, (ii) to transmit the user mechanical efforts in part to the regulating insole 14 and in part to the sole 16 during the advance phase of the foot when walking or running, (iii) to receive the regulating insole 14 and the sole 16 mechanical response during the foot support phase on the ground or floor and to transmit it to the user, for utilization in the next advance phase, and (iv) to permit the perspiration pass, principally into the regulating insole 14 and secondarily into the environment through the cover 18.

#The regulating insole 14 is located between the body 12 and the sole 16 and includes an absorbent layer 22, an elastic, resilient layer 24 and a closure layer 26, whose functions are as follows: (i) to receive the mechanical efforts transmitted by the body 12 and use same in its convenient deformation, thus fulfilling its expansion cycle and delivering the energy surplus to the sole 16, (ii) to receive the sole 16 mechanical response in the foot support phase on the ground or floor and use it in its deformation, thus fulfilling the compression cycle thereof and delivering the energy surplus to the shoe body 12, (iii) to receive perspiration from within the shoe 10 and discharge it into the environment, except for part of the perspiration gaseous phase which is delivered to the sole 16.
