A process of making a family cell of homogenous inner bladders with varying elasticity includes a forming a plurality of inner bladders from a first material with a first elasticity. The inner bladders have interior surfaces during inner chambers and exterior surfaces exposed to an outside environment. The inner chambers are configured to store a fluid. A family cell is formed by fluidly connecting the inner bladders. One or more hybrid bladders are selected from the inner bladders and a second material having a second elasticity is applied to the hybrid bladders. The second elasticity is less than the first elasticity, such that the second material reduces the elastic qualities of the hybrid bladder.

The utility model relates to the light industry and is intended for use as a prophylactic and hygienic means for human feet. A shoe insole with amber consists of a base and filler, wherein the base is made of an adhesive composition, in which the filler is located, and the filler is amber stones. The insole allows maintaining the prophylactic and hygienic effect during a long-term use thereof.

A robotic shoe which provides real-time feedback regarding forces acting on the foot of the user, in order to modify these forces in a corrective or diagnostic manner The shoe comprises an insole equipped with embedded pressure sensors enabling it to continuously monitor the ground reaction forces (GRF) and the foot center of pressure (COP) while the user is standing, walking, and running. The insole COP and GRF readings are input to a programmable system that shifts the COP trajectory dynamically in a patient-specific manner via the robotic platform of the shoe. The robotic platform contains motors that control elements whose movement manipulates the forces acting on the foot and lower limb, resulting in modification of the GRF. Closed loop feedback enables a dynamic fit of an optimal COP. The COP and GRF information can be stored for analysis and diagnosis of gait and instability events accruing during locomotion.

The invention relates to an insole (100) for shoes, in particular as a disposable product, having a top layer (200) that comprises a two-ply basic material and faces the foot, and a base layer (202) that is connected to said top layer (200) and faces the shoe, and having a foot surface (104) that faces the foot and an opposite Sole surface (102) that laces the shoe, wherein the top layer (200) and the base layer (202) consist of a staple-fibre nonwoven and bicomponent fibres and absorbent cellulose-based fibres and/or hydrophilic synthetic fibres are contained in the top layer and in the base layer, and wherein the insole has a combination comprising at least two different active-substance groups, the active-substance groups being selected from the group of antimicrobial active substance, odour absorbent and odour-masking substance, and both the base layer (202) and the top layer (200) being assigned at least one active-substance group.

A method of forming a sole structure for an article of footwear. The method includes depositing a first outsole material including a first uncured polymeric material upon a mold surface of a mold cavity. The method also includes disposing a midsole element adjacent to the first outsole material within the mold cavity and subjecting the first outsole material and the midsole element to a molding process to form the sole structure having an outsole and a midsole.

Systems and methods for supporting an object to be printed in an additive manufacturing process are disclosed. Support structures (202, 302, 402, 502, 602) are prefabricated and positioned in the build area of a 3D printing device prior to printing the 3D object. When the object has been printed, the support is removed and can be reused to print another object by repositioning the support structure in the building area of the additive manufacturing device.

A shoe insole (28) comprises a base layer (34) and an optional top layer (36). The base layer (34) comprises functional zones (40) configured according to a user's physiological data, needs, and intended use. The insoles (28) may either partially or wholly be made using additive manufacturing techniques.

An insole for a shoe, in particular for a sports shoe, having a first sole section with a standing surface for a user's foot. The first sole section extends vertically over a specified first height when the insole is used as intended. At least two second sole sections are arranged below the first sole section. A second sole section is arranged in a front section of the insole and a second sole section is arranged in a rear section of the insole viewed from the sole longitudinal direction. The two second sole sections extend over a specified second height in the vertical direction when the insole is used as intended and at least one elastic element connects the two second sole sections, each of the two ends of the elastic element engaging with a respective second sole section within the extent of the second height.

Improved soles and insoles for shoes, in particular sports shoes, are described. In an aspect, a sole for a shoe, in particular a sports shoe, with at least a first and a second surface region is provided. The first surface region comprises expanded thermoplastic polyurethane (TPU). The second surface region is free from expanded TPU.

A sole structure for articles of footwear and a method of manufacturing them comprising at least one polymeric foamed component expanded through supercritical fluid (SCF) expansion of a shaped pre-expanded polymeric material. The polymeric foamed component may include apertures situated and fashioned in the formation of the pre-expanded polymeric material to promote uniform expansion and optimal curing conditions during the SCF expansion process. At least one polymeric foamed component having one set of physical properties that may be bound to or assembled in conjunction with one or more sole components having the same or another set of physical properties.
