Abstract

Disclosed is a design for footwear cooling sole structures. The structures are with multi holes under the foot bed connected to the tunnels underneath; the tunnels are opened to the outside of shoes through side walls & bottom, which to allow soles of feet of wearers directly contacting to the flesh air outside of the shoes. The design is including the structure of tunnels in one material; and the structures of tunnels created by the assembly of different layers of materials. The design of the tunnels and tunnels' opening can force more air move towards the foot bed while the wearer is walking. The design of position of holes & tunnels' opening on bottom can efficiently prevent the debris on the pavement pricking to the wearer's feet directly. Equipped with ventilated upper, this design is available for many kinds of shoes, such as slippers, sandals, office shoes, sneakers, sports shoes & etc.

Footwear Cooling Sole Structure

SUMMARY OF THE INVENTION

FIELD OF THE INVENTION [0006] The aim of the present invention is to

[0001] The present invention relates provide a shoe with a ventilated sole which is in generally to footwear, and in particular to a simple structures, easy for manufacturing, and cooling sole system for a shoe that allows for with good cooling & vapor exchanging improving cooling performance & vapor performance on foot beds.

exchanging on the foot bed. [0007] The structures are with multi ventilated holes directly connected the foot bed

BACKGROUND OF THE INVENTION surface to the tunnels which are underneath. The

[0002] Nowadays in summer time, people are tunnels underneath are opened to the outside of more preferred wearing airy shoes with good shoes from side walls, bottom & front side. cooling performance. Most of the related Through the ventilated system created by these products in the markets are mainly focused on holes, tunnels and tunnel openings, soles of feet the breathability on the upper construction & of the wearers are directly contacting to the flesh materials. There are also some breathable air outside of the shoes.

designs on the bottom; however, many of the [0008] The design is including the structure parts are complex for construction, which is of tunnels in one material of a molded midsole; more difficult for manufacturing, or with and the structures of tunnels created by the less-then-ideal performance. assembly of different layers of materials, such as

[0003] Most of the shoes are with fabric or with molded midsole & outsole, or 2 layers of leather on foot bed surface, the fabric or leather die cut midsole sheets with rubber outsole. can absorb some vapor from human soles. [0009] The design of the tunnels, and the However, the vapor is stayed on the foot bed of design of tunnel opening on side walls, on the the shoes, which create foot odor. bottom & in the front side, can force more air

[0004] Meanwhile, there are lots of products move towards to the foot bed surface inside the in the market now are with plastic molded foot shoes while the wearer is walking, which can beds without fabric or leather layer on surface, achieve a better ventilation performance.

feet of wearers are directly contacting to the [0010] In another hand, the design of the plastic surface on the bottom. It can be positions between the holes connects to the foot comfortable on cushioning. However, without an bed, and the tunnels opening to bottom, can effective ventilation system on the bottom, the efficiently prevent the sharp objects, such as foot odor issue will be more serious. All vapors sharp stones, branches and other debris on the stayed on the surface of foot bed inside the shoes. pavement, pricking to the wearer's feet directly. The shoes are easy heat & wet after wearing for [0011] The design is easy for manufacturing. a while, creates ideal environment for fungi & For the molded midsoles, the holes & tunnels are bacteria. Fungi & bacteria consume dead skin in the same molded parts, which avoided lots of cells from foot & release garbage which create detail matches during assembly. Without a foot odor. separated foot bed, feet of wearers are directly

[0005] People are preferred lighter shoes in contact to the ventilated midsole. Uppers are summer. With holes & tunnels in the same connected to the sole edges directly by bonding material, it can reduce around 15% of weights of and stitching, which don't need to go through the the soles. For injection parts, it can save around traditional shoe making process of stroble or [0012] Equipped with ventilated upper in bottom side of the 2 separate parts for FIG 13 different construction & materials, this design is [0028] FIG 16 is the side view of the sneaker available for many kinds of shoes, such as with the tunnels created by 2 molded parts for slippers, sandals, office shoes, sneakers, sports the sole.
