A torsion-resistant three-density high rigidity midsole includes a midsole body having a front region, a back region, and a middle region integrally connected between the front and back regions. The front region has a front region density and a front region length. The back region has a back region length, and a back region density smaller than the front region density. The middle region has a middle region length, and a middle region density greater than the front region density. A sum of the front and middle region lengths is greater than the back region length. A cushion body is integrally formed on a top surface of the midsole body, and covers the front, middle and back regions. An elastic piece is sandwiched between the top surface of the midsole body and a bottom surface of the cushion body at a position corresponding to the middle region.

A method for making a moisture-permeable waterproof shoe includes: (A) sleeving an inner sleeve unit on a last; (B) coating a bonding agent on an inner surface of an upper unit; (C) sleeving the upper unit on an assembly of the inner sleeve unit and the last; (D) placing an assembly of the upper unit, the inner sleeve unit and the last in a heating device; (E) placing the assembly in a vacuum bag; (F) placing the vacuum bag in a freezing device; (G) removing the assembly from the vacuum bag; (H) pulling out the last from the inner sleeve unit; and (I) fixing a sole to a bottom portion of a three-dimensional upper structure.

Method for making moisture-permeable waterproof shoe having integrally formed upper

A moisture-permeable waterproof shoe includes an outer shoe body unit including an outer shoe upper, a midsole and an outsole. The outer shoe upper and the midsole cooperatively define an insertion space. A sock-shaped inner shoe body unit is disposed in the insertion space and includes a moisture-permeable waterproof shoe-shaped inner sleeve, an outer sock body having a sock body portion sleeved on the shoe-shaped inner sleeve, and an inner adhesive layer adhered between an outer surface of the shoe-shaped inner sleeve and an inner surface of the sock body portion. A connecting layer is fixed between the outer shoe upper and the sock body portion and between the midsole and the sock body portion.

A multi-style moisture-permeable waterproof shoe includes an outer shoe body unit defining an insertion space, and a plurality of sock-like inner shoe body units inserted removably and selectively into the insertion space. Each sock-like inner shoe body unit includes a moisture-permeable waterproof shoe-like inner sleeve and an outer sock body. The shoe-like inner sleeve defines a foot space and is made from at least one cut piece. The outer sock body has a sock body portion sleeved on the shoe-like inner sleeve. An inner adhesive layer is adhered between an outer surface of the shoe-like inner sleeve and an inner surface of the sock body portion.

A zipper-free moisture-permeable waterproof high-top shoe includes a high-top inner sock body having a first foot portion and a first leg portion cooperating with each other to define a foot space. A moisture-permeable waterproof high-top shoe-like sleeve is sleeved on the high-top inner sock body and has a second foot portion. A moisture-permeable waterproof low-top shoe-like sleeve is sleeved on the second foot portion and has a sleeve body. A high-top outer sock body is sleeved on an assembly of the inner sock body, the high-top shoe-like sleeve and the low-top shoe-like sleeve, and has a third foot portion. A sole is fixed to a bottom portion of the third foot portion.

Zipper-free moisture-permeable waterproof high-top shoe

A method of making a moisture-permeable waterproof shoe includes: cutting a substrate to form a cut piece having a main body and two wing portions; ultrasonically welding rear mating edges of the main body, wing lateral edges of the wing portions, front and rear curved edges of each wing portion respectively to a front convex portion and a lateral connecting edge of the main body to form a shoe-like inner sleeve: sleeving the inner sleeve on a shoe last; coating an adhesive on an inner surface of an upper; sleeving the upper on the shoe last and heating the assembly to form a moisture-permeable waterproof foot cover; and fixing a bottom portion of the moisture-permeable waterproof foot cover to a sole.
