Abstract: In a process for making a waterproof shoe, an upper and a waterproof lining unit with open top and bottom ends are prepared. The lining unit is placed within the upper, and the top ends of the upper and the lining unit are interconnected. A cover member is then attached to the bottom end of the upper to close the bottom end of the upper. After an outsole is attached to the bottom end of the upper, the lining unit is pulled out from the upper through the top end of the upper so that the bottom end of the lining unit moves away from the upper. The outsole is then sewn to the bottom end of the upper, thus forming a reinforcing sewing line that interconnects the outsole and the upper. Thereafter, the lining unit is re-inserted into the upper.

Abstract: A waterproof shoe includes a waterproof breathable lining sleeve which is mounted inside an upper and which is made of an air-permeable waterproof material, and a cup member attached to a bottom end of the lining sleeve. The cup member is made of an air-impermeable waterproof material and includes a cup bottom which has a toe region and a heel region, and a cup wall which projects laterally and upwardly from said cup bottom and extends around the toe and heel regions. Preferably, the cup member is a molded body formed by a molding process, and the bottom end of the upper is lasted over the cup bottom.

Abstract: A shoe includes a hollow insole component which has a horizontal part with an inner peripheral end confining an opening and an upward flange extending upward from a top face of the horizontal part, an upper having a bottom open end attached to the horizontal part; and a lining mounted within the upper and having a bottom open end attached to the upward flange, wherein the hollow insole component is made by forming an elongated strip into a loop, and the insole component has a connection joint extending transversely of the hollow insole component.

Abstract: A shoe includes an upper which has a substantially U-shaped first notched edge, a first cutout confined by the first notched edge, and a connection seam spaced apart from and extending around the first notched edge, an inner lining which is disposed inside the upper and has a second notched edge corresponding in position to the first notched edge; and a tongue which is waterproof and which has a marginal end. The marginal end of the tongue is attached to the upper along the connection seam and is attached to the inner lining along the second notched edge.

Abstract: A shoe includes an upper with a first notched edge, an inner lining disposed inside the upper and having a second notched edge in alignment with the first notched edge, and a sock-like waterproof lining made of a waterproof breathable membrane and disposed between the upper and the inner lining. The waterproof lining has a third notched edge in alignment with the first notched edge. An elastic part spans the first, second and third notched edges, and has an outer layer and an inner layer both of which are elastic. The inner layer has a peripheral edge attached to the second notched edge to form an inner seam. The outer layer has a peripheral edge attached to the first notched edge to form an outer seam. The third notched edge is attached to one of the first and second notched edges along one of the inner and outer seams.

Abstract: An insole includes an insole pad which has a toe section, a heel section and a shank section and which is constituted of top and bottom sheets heat sealed together. The top and bottom sheets confine therebetween a first air chamber in the toe section, a second air chamber in the heel section and an air passage in the shank section. The air passage is relatively narrower than the first and second air chambers. A compressible resilient member is disposed in the second air chamber so that, when the heel section is compressed and released, the second air chamber can act as an air pump to draw air into the first air chamber and force the air out of the first air chamber through vent holes formed in the toe section.
