A moisture-permeable waterproof shoe includes an upper unit and a shoe-shaped inner sleeve. The upper unit includes a top cut piece and a bottom cut piece. The top cut piece has a rear concave edge with two spaced-apart first ends, a peripheral edge with two spaced-apart second ends, and two rear mating edges each interconnecting one of the first ends and a respective second end. The peripheral edge of the top cut piece is sewn to a periphery of the bottom cut piece. The top and bottom cut pieces cooperate to define an interior space. The inner sleeve is disposed in the interior space. A connecting layer is fixed between an inner surface of the upper unit and an outer surface of the inner sleeve. A sole is fixed to a bottom portion of the upper unit.

A moisture-permeable waterproof shoe includes an upper unit, an inner sleeve unit, and an outsole unit. The upper unit defines an inner space having a top open end and a bottom closed end. The inner sleeve unit is fixedly disposed in the inner space, and includes a moisture-permeable waterproof shoe-like inner sleeve and a thermoplastic polyurethane (TPU) sheet. The moisture-permeable waterproof shoe-like inner sleeve has an inner sleeve bottom surface and defines a wearing space having a top open end and a bottom closed end. The TPU sheet has a top surface fixedly connected to the inner sleeve bottom surface by a high-frequency welding method. The outsole unit is fixedly connected to an underside of the upper unit.

The present invention discloses a safer sole against slippage while worn wet, and one which is pleasant to wear, practical to use, and economical to manufacture. The invention discloses a footwear sole through an innovative means of allowing water to clear from a foot, and under a footwear. It is also the purpose of this invention to provide for an aerating sole via open through and through channels for improving foot hygiene while maintaining the safety of a foot from being poked or pricked if stepping on pointy objects.

The invention relates to a shoe insert comprising a cover layer, a damping layer, and an absorbent core for receiving a liquid fragrance, wherein the damping layer has a depression on its upper side for receiving the absorbent core, wherein the cover layer is arranged above, and covers, the damping layer and the absorbent core, wherein the layers are connected to one another, and wherein a hole-shaped recess is formed in the cover layer in the region of the absorbent core for supplying the absorbent core with liquid fragrances.

A method of forming and shaping a waterproof and moisture permeable shoe upper includes disposing a shoe upper and a waterproof and moisture permeable film on a shoe last, wherein at least one of the shoe upper and the waterproof and moisture permeable film includes microwave treatable material, and heating the shoe last with the shoe upper and the waterproof and moisture permeable film thereon by microwave, so that the shoe upper and the waterproof and moisture permeable film are combined by the microwave treatable material and shaped to form the waterproof and moisture permeable shoe upper after cooling.

A footwear insole includes a base layer configured to overlie a sole of an article of footwear, a moisture permeable layer overlying the base layer, and an airgap structure captured between the base layer and the moisture permeable layer. Perimetric edges of the base layer, the airgap structure and the moisture permeable layer are aligned to form an insole perimetric edge.

A shoe with an upper that is at least partially rendered impermeable, including a sole; an insole; an upper assembly, which at least comprises a breathable lining, a breathable upper, and, interposed between at least part thereof, a layer that is waterproof and is fixed hermetically below the insole, the upper assembly being associated with the insole; and a region providing a waterproof seal of the insole to the sole, the sealing region substantially surrounding the breathable or perforated portion that is free for perspiration.

A waterproof garment, such as a shoe, is formed from a first seamless circular knitted liner, which is coated with resin and cured to form a waterproof layer. The first liner is fitted within a second seamless circular knitted liner. In the case of a shoe, a sole can be attached and a reliably waterproof shoe is thereby provided which can be efficiently manufactured. In another embodiment, the combined liners are used as a waterproof lining for a shoe upper.

An article of footwear includes a sole structure, an upper, and a securing mechanism. The upper comprises a toe region, a midfoot region, a heel region, a lateral side, and a medial side, and is coupled to the sole structure. The securing mechanism is fixedly attached to the upper and comprises a forefoot portion and a heel lock element. The heel lock element has a first and a second end and extends from the lateral side of the upper, passes around the heel region of the upper, and extends to the medial side of the upper. The heel lock element comprises a stiffness that is greater than the stiffness of the upper and is configured such that tensioning the securing band adjusts the heel segment of the main portion relative to a wearer's heel.

The disclosure relates to seamless manufacturing processes for 3-dimensional waterproof and breathable porous polymer membranes by spraying, dip-coating or painting a substrate with a dispersion having polymer, coated or non-coated particles and diluent and removing the particles by dissolution thus creating porosity after the 3D coating/shaping. The disclosure further relates to dispersions to obtain such membranes, to polymer membranes obtained, to shaped articles containing such membranes; to the use of such membranes, shaped articles and intermediates.
