Detailed ways

The structure and effect of the present invention will be described in detail by citing the following embodiments in conjunction with the accompanying drawings.

As shown in FIGS. 1-3 , a shoe 10 with a double-density midsole provided by the first preferred embodiment of the present invention includes a midsole 20 , a bottom platform 30 , and a vamp 40 .

The midsole 20 includes a first layer 21 for the sole of the user to contact, and a second layer 22 connected under the first layer 21 . The second layer 22 is flat; the first layer 21 has a bottom 212 and a plurality of ribs 214 integrally extending upward from the bottom 212, and each rib 214 extends laterally to the left and right sides of the midsole 20. side, and each convex rib 214 is equidistantly distributed, and the distance L between the top of each convex rib 214 and the bottom 212 of the first layer 21 is 2-4 mm. The first layer 21 and the second layer 22 of the midsole 20 can be made of ethylene vinyl acetate copolymer (Ethylene Vinyl Acetate Copolymer; EVA for short), polyurethane (Polyurethane; PU for short) or polyvinyl chloride (Polyvinylchloride). ; PVC) and other polymers are made of foaming materials as raw materials, but the material density of the first layer 21 is larger than the material density of the second layer 22, and the hardness of the first layer 21 is greater than the hardness of the second layer 22, The midsole is measured with a hardness meter conforming to JIS S6050 of Japanese Industrial Standards or SRIS 0101 of Japan Rubber Association. The hardness values of the first layer 21 and the second layer 22 are 37 and 22 respectively. 28. Of course, the manufacturer can also freely adjust the hardness of the midsole 20. The actual test found that the hardness value of the first layer 21 is preferably between 35-40, and the hardness value of the second layer is preferably between 25-30. Preferably, the hardness difference between the first layer 21 and the second layer 22 is preferably between 5-10.

The bottom platform 30 includes a spacer layer 31 connected under the second layer 22 of the midsole 20 , and a shoe bottom layer 32 connected under the spacer layer 31 . The spacer layer 31 is flat and has three accommodating holes 312; the sole layer 32 is composed of five thinner sheets 322 and four thicker blocks 324, and each block 324 is connected to Between two adjacent sheet bodies 322, the bottom of the base 30 is sequentially formed with a front hollow area 33, a front support area 34, a rear support area 35, and a rear hollow area 36, wherein the front The support area 34 has two front bumps 342 in contact with the ground, and a front groove 344 formed between the two front bumps 342, and the rear support area 35 has two rear bumps 352 in contact with the ground, and a front groove 344 formed between the two front bumps 342. The rear groove 354 between the two rear protrusions 352 .

The vamp 40 is disposed above the midsole 20 and has three fixing portions 42 respectively limited in the receiving holes 312 of the spacer layer 31 . A space is formed between the vamp 40 and the midsole 20 for the user's foot to wear, so that the user's foot will not be separated from the shoe 10 when walking.

When the shoe 10 is in use, the special design of the base 30 not only prevents the soles of the user from getting wet due to wading, but also effectively releases the pressure on the soles of the feet, allowing the user to walk smoothly. More importantly, as shown in FIG. 4 , when the user's sole is in contact with the midsole 20 , the soft second layer 22 of the midsole 20 will elastically compress and deform while buffering the pressure of the user's sole. In addition, the convex ribs 214 of the first layer 21 of the midsole 20 will produce elastic bending deformation along the force direction of the user's sole, so that the effect of releasing the pressure of the sole of the sole of the midsole 20 is better, thereby improving the comfort of the shoe 10 .

The above-mentioned midsole 20 can also be applied to other types of shoes other than slippers, such as the leather shoes shown in FIG. 5 , and the upper 40 and the base 30 can vary with different types of shoes. In addition, the protruding ribs 214 of the midsole 20 can also extend longitudinally forward and backward, or extend in any other direction, and are not limited to laterally left and right.

Finally, it must be stated again that the constituent components disclosed in the foregoing embodiments of the present invention are only for illustration and cannot be used to limit the scope of patent protection of the present invention. The substitution or change of other equivalent components shall be covered in In the patent protection scope of the present invention.
