An outsole for a shoe includes i) a main tread to be secured to a shoe, the main tread having a sole portion and a heel portion, ii) at least one non-slip element integrated to the main tread and being positioned within one of the sole and heel portions; and iii) a retractable crampon, including at least one spike, that is mounted to the other one of the sole and heel portions of the main tread. The retractable crampon is movable between a deployed position, wherein the at least one spike extends from the main tread, and a retracted position, wherein the at least one spike is prevented from contacting the ground by the main tread.

The present disclosure provides an inflatable shock-absorbing sole structure, which includes a sole and at least one convex arranged on the sole, an airbag room is formed in the convex, and an airbag is arranged in the airbag room, the airbag room and the airbag are stretchable and compressible. The shock-absorbing sole structure further includes a built-in air-charging device, when the airbag needs to be inflated, the air-charging device can inflate it. The present disclosure provides a shock-absorbing sole structure, the airbag room and the airbag form a shock absorption system in the sole structure, which endows the sole structure a better shock absorption effect. Further, by mounting a built-in air-charging device in the sole structure, when the air bag needs to be inflated, the built-in air-charging device can inflate it.

Presented are footwear sole structures with pressure-mapped midsole topographies and inlaid wear-mitigating outsoles, methods for making/using such sole structures, and footwear fabricated with such sole structures. An article of footwear includes an upper for receiving and attaching to a foot of a user, and a sole structure attached to the upper for supporting thereon the user's foot. The sole structure includes a midsole that is formed with a first material having a first hardness, and an outsole that is mounted to the midsole and formed with a second material that is harder than the first material. The midsole has a ground-facing surface with multiple cavities, multiple channels interspersed with the cavities, and ground-contacting land segments that separate the cavities from the channels. The outsole is disposed in the channels and positioned between the cavities such that a ground-contacting outsole surface is substantially flush with the midsole's ground-contacting land segments.

A method for forming a molded article having an insert includes temporarily protecting features of the insert during a molding process using a malleable plugging material. In one step, the method includes disposing a plug including the plugging material within a receptacle of the insert, where each receptacle includes an engagement feature. The insert and the plugging material are placed into a mold, and a liquid molding material is applied to an exterior surface of the insert. The liquid molding material is solidified, forming the molded article including the insert embedded in the solidified molding material. The molded article is removed from the mold, and the plugging material is removed from the receptacle of the insert that is embedded in the molded article to expose the engagement feature.

The invention relates to an insole (100) for shoes with a base material, which comprises a sole surface (102) facing the shoe and an opposite foot surface facing the foot, wherein a coating (112) is provided on the sole surface (102), which provides the sole surface (102) of the insole (100) with an increased frictional force with respect to the uncoated sole surface (102), characterised in that the coating (112) is formed from a plurality of individual patterns (120) formed from coating lines (114), which are discrete from one another and are arranged in such a way that they cannot be formed by one or more continuous coating lines (114) miming continuously from a first side (122a) of the sole surface (102) to an opposite second side (122b) of the sole surface (102).
