As shown in Fig. 1 and Fig. 2, the embodiment of the utility model provides a multi-layer composite sole structure that improves wearing comfort, including a rubber sole 20, and the rubber sole 20 includes padding in sequence from far to near to the sole of the foot. Material layer 21, breathable foam layer 22 and breathable insole layer 23, the position corresponding to the sole of the foot on the filler layer 21 is provided with sole filler area 212, is filled with massage filler in the sole filler area 212, on the breathable foam layer 22 Arc-shaped protrusions 221 are provided at the positions corresponding to the soles of the feet, and the air-permeable foam layer 22 is deformed under pressure during the stepping process, and returns to its shape when there is no pressure. The rubber sole 20, the filler layer 21, the air-permeable foam layer 22 and the air-permeable insole layer 23 can be fixed by sewing or bonding.

In the above scheme, the rubber sole 20 is made of rubber material. Filler layer 21 can be filled with for example any one or more massage fillers in linseed, cork chips, latex pads or memory foam, and the effect of filler layer 21 has two: the first, can carry out on sole when wearing. Massage to improve wearing comfort and health care function; second, as the filler layer 21 wears longer, the footbed will form a wrap-fitting support for each person's unique foot shape, and this support can accurately act For the purpose of shock absorption and cushioning, it will give the wearer the feeling of walking on the fine sand of the beach. Among them, flaxseed is an annual herb, the seed of flax. It is a small reddish-brown fruit that can improve the fat content of the skin, making the skin smoother, moisturized, soft and elastic, and at the same time make the skin breathe and perspire normally. Soft wood chips are soft and dry wood chips. The latex pad is a cushion-shaped product made of rubber tree sap through evaporation molding. Because it has numerous pores, it has good air permeability; at the same time, the latex pad has excellent elasticity, is not easy to deform, can prevent mites and bacteria, and can meet different body weights. The needs of the crowd, good support can adapt to the user's various pedaling actions. Memory foam is also called slow rebound, which refers to the ability of the material to deform slowly. After being deformed by an external force, it will slowly return to its original shape. The material has a characteristic of both viscosity and elasticity, absorbs impact kinetic energy, and can be used repeatedly. And it will not be permanently deformed, such as the polyurethane slow-rebound sponge (memory foam) in the prior art.

The air-permeable foam layer 22 is made of foam with good air permeability. Foam is a material foamed by plastic particles. Foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, PORON , CR, EVA, bridging PE, SBR, EPDM, etc. Among them, PORON foam is a high-density polyurethane foam produced by Rogers Company in the United States. It has the advantages of small compression residual deformation, high energy absorption and high cushioning.

Breathable insole layer 23 can adopt the cushion layer material that air permeability is good in the prior art, abrasion resistance is good, softness is excellent, for example can adopt wild deerskin, there are 25 million wild deer in the U.S., because there are no natural enemies, the government is to control In order to maintain the ecological balance, the hunting period is opened every year. Raw materials such as buckskin are mainly used for various precision and luxury goods, and the unit price is expensive, so they are rarely used in footwear products. In order to pursue the ultimate touch, buckskin is used. The wild deerskin imported from the United States is used, and it is treated by water dyeing process, which is healthy and environmentally friendly, without adding chemical coatings, and has good skin-friendly properties. It is soft, strong, with large porosity, sufficient toughness, excellent hand feeling, and has a velvet-like touch. Compared with pigskin, sheepskin, and cowhide, deerskin is the softest genuine leather material. Its price is relatively expensive, and its stock is small. Only a few leather goods with high requirements for softness and comfort are used. In order to obtain a natural, healthy and comfortable inner leather material, the deerskin used is made of pure water dyeing process without chemical coating. The pure water dyeing process does not add finishing or trimming to the leather embryo, and the deerskin itself will be retained. Pores and fibrous tissue characteristics, in order to achieve soft and skin-friendly moisture-wicking and breathable performance. However, deerskin itself is smaller than cowhide and has more growth lines. Wild deerskin may be bitten by insects and flies, scratches, etc. in outdoor activities. Differences, etc., all of which form natural stains, wrinkles, scars, color differences, and texture features on the finished leather. Although the factory will manually select them during use to avoid obvious blemishes, these features still exist. These characteristics are considered and accepted by the industry as the natural beauty of leather, and domestic consumers have also begun to accept and like this natural leather.

In the above scheme, the air-permeable foam layer 22 is provided with an arc-shaped protrusion 221 at the position corresponding to the arch of the foot. The arc-shaped protrusion 221 has a three-dimensional arc-shaped structure, and the arc design at the arch of the foot can increase the adhesion between the foot and the shoes. The fit provides comprehensive support for the sole of the foot, reduces the stress on the forefoot, and enhances comfort. For some women's high-heeled shoes with relatively high soles, this fitting design that fits the soles of the feet has a good support effect on the soles of the feet and improves wearing comfort.

The above scheme adopts the design that the filler layer 21 is located between the rubber sole 20 and the air-permeable foam layer 22. When the filler layer 21 is filled with flaxseed, the flax in the filler layer 21 will The seeds will move to the edge with the pressure on the soles of the feet, that is, the pressed linseeds "flow" to the side of the soles of the feet with the pressure, so that the soles fit the shape of the feet and improve comfort. This technology is different from the existing hard soles. The difference between this solution and the existing sole is that DST solid replacement technology (Displaceable Solid Technology) is adopted. The breathable foam layer 22 of the sole and the latex pad that can be filled in the filler layer 21 have strong plasticity. , will form a footbed shape suitable for the wearer's foot shape, which improves the adaptability of wearing.
